Thanks for the explanation. Are there four reliable online sources you would suggest? Or do I need to go to the library? And if so, do you have suggestions there?

::Here's some I found.  Oddly, it's harder than I thought to find the right level of resources - much of what's online is either too simple (geared at kids) or highly technical (and sometimes behind a paywall).

== Your expertise requested about [[Collodictyon]] ==

Hi this article is really in trouble, but with huge interest in terms of pageviews, apparently a single-celled creature which propels itself (apparently) with four flagella. Wondering if you might point us to better sources. It was in the news recently with a (possibly hyped?) story about how it is one of Earth's oldest living organisms, possibly an ancestor to humans and evolutionary clue, and lived only in a lake in Norway (which we originally thought was [[Lake As]] but we think we've got the lake down now via redirect). If you have free time to help we'd be grateful, thanx.--[[User:Tomwsulcer|Tomwsulcer]] ([[User talk:Tomwsulcer|talk]]) 11:58, 30 April 2012 (UTC)

I reported an ip for making a BLP, on WP:ANI , he mentions your name as one of two people that have reverted him
[http://en.wikipedia.org/enwiki/w/index.php?title=Wikipedia:Administrators%27_noticeboard/Incidents&action=edit&section=55 | Check here for it, it's labeled as "Legal Threat or Now" ] .  Perhaps you can shed more light on it.    Looks like it may be Australia's "Snake Man " himself based on his edits

::Yeah, that's almost assuredly him.  He has a reputation for roving the net to both promote his ideas and threaten legal action against those disagreeing with him or criticizing him.  He's edited WP many, many times before, mostly either his own WP page (either to sanitize it or engage in promotion) or a few snake taxa he's "published" on (his taxonomy is legendarily awful, to the point that Nature itself identified him by name as an example of why amateur taxonomists are bad for science).  His most recent "dispute" (which resulted in vandalism of my talk page a few hours ago) concerns the genus names for the white-lipped and reticulated pythons, which he claims to have re-named (the revisions have not been accepted by any workers in the field).  Contrary to his wishes, WP:Amphibians and Reptiles adopted a universal policy of using the (relatively slow and conservative) ITIS database for snake taxonomy, in order to prevent us from having to move pages and redirect links every time a paper is published.  While Hoser's antics have certainly not endeared him to me, my reversion of his most recent edits is purely a policy matter. [[User:HCA|HCA]] ([[User talk:HCA#top|talk]]) 18:00, 24 July 2012 (UTC)

== Edit: Convergent evolution ==

I don't think you understood my edit here:[http://en.wikipedia.org/enwiki/w/index.php?title=Convergent_evolution&diff=prev&oldid=518808347] I didn't ''add'' those terms; instead, what I did was move that paragraph from below in order to form a more logical narrative flow.  If you believe "Neither term is used correctly", then that paragraph should be ''deleted''.  Your reversion here:[http://en.wikipedia.org/enwiki/w/index.php?title=Convergent_evolution&diff=next&oldid=518808347] simply moved it back (and removed link: [[evolutionary relay]]). ~Eric F [[Special:Contributions/74.60.29.141|74.60.29.141]] ([[User talk:74.60.29.141|talk]]) 08:59, 23 October 2012 (UTC)

Ah, my bad, I guess I didn't look thoroughly enough.  Anyhow, I've edited it again to correct the parallel evolution example and remove the "evolutionary relay" bit, since the term seems to be almost never used and apparently means something quite different.

== Reptile taxonomy ==

I'm somewhat puzzled by [http://en.wikipedia.org/enwiki/w/index.php?title=Rhacodactylus_sarasinorum&diff=525568949&oldid=522970453 this] and other reptile reverts where you've used a similar argument (only speaking about the taxonomy; not other things you reverted there). Looking at [[WP:AAR#Taxonomy]], it is clear that a specific source only has been chosen for higher level taxonomy (the infrequently updated and by now highly out-of-date ITIS). At lower levels none has been chosen. That leads to one of the core wikipedia policies, WP:NPOV (e.g., subsections "[[WP:NPOV#Good research|Good research]]" and "[[WP:BALANCE|Balance]]"). We now have [http://www.mapress.com/zootaxa/list/2012/3404.html clear evidence] that ''Rhacodactylus sensu lato'' is problematic, resulting in the validation of ''Correlophus''. Publications presenting comparable evidence for the opposite view (all in ''Rhacodactylus'') are lacking. I note that the lead author of the 2012 paper is Bauer, the top authority on this group, and that the single most complete online database (reptile-database.org) has followed the split too. The recently described ''C. belepensis'' would present an additional problem if sticking with one genus. We'd have to disregard it entirely; adding it as the only species of ''Correlophus'' would be [[WP:OR]] (no one has suggested the genus is monotypic) and adding it as ''R. belepensis'' would also be WP:OR (no authority has placed it in ''Rhacodactylus'').</br>
In summary, I'm struggling to find any good argument for keeping the two genera together. While [[Special:Contributions/Chevyrumble55|user:Chevyrumble55]] certainly should have provided a source when he made the changes, based on your edit summary it appears you were aware of the source, but disregarded it. However, beware that Chevyrumble55 made a spelling mistake: ''Co<u>r</u>e<u>ll</u>ophus'' instead of the correct ''Co<u>rr</u>e<u>l</u>ophus''. If you insist on preserving the outdated taxonomy, please note that Chevyrumble55 removed the two ''Correlophus'' (''chahoua''+''ciliatus'') from the species list in ''[[Rhacodactylus]]'', and modified [[Diplodactylinae]] too. I'll leave possible edits dealing with these taxonomic issues to you and other editors.

== Thanks for caring about the Burmese Python article ==

Thank you for your love of snakes and substantial authorship of the Burmese Python article.  

Could you find it in your heart to allow the article to mention that Burmese pythons are snakes that grow quickly to large size, and have proven capable of attacking and seriously injuring or killing infants, children, and adult humans (including experienced snake handlers) as ably detailed by the Humane Society report, {{cite web|last=Humane Society|title=Constrictor Snake Attacks|url=http://www.humanesociety.org/assets/pdfs/wildlife/captive/constrictor-snake-attacks.pdf}}?  

This factual information will not help sell any snakes, but it is salient to unsophisticated potential snake buyers who rely on Wikipedia for useful information.  Its omission leaves the article reading like sales talk for buying one of these wild animals, which the article describes as attractive and popular.

:The HSUS is an advocacy group, one that has the explicit goal of ending all exotic pet ownership, from Burmese pythons to betta fish.  Extremist animal-rights organizations like the HSUS are not a reliable source, and cannot be used on WP.
:Furthermore, the excessive focus on their dangers is out of place - WP is not here as a pet guide, either for or against any species.  You don't see any such notes on the pages for wolves or ocelots or sharks, so it doesn't belong with Burmese pythons. [[User:HCA|HCA]] ([[User talk:HCA#top|talk]]) 19:05, 7 July 2013 (UTC)

== To underscore the rarity of Burmese pythons over 5 metres, might the Wikipedia article mention this 2013 find ==

To underscore the rarity of lengths over 5 metres, might Wikipedia's Burmese python article mention this 2013 find, which by subtraction reveals that the previous record in Florida was less than 17 feet long, and thus not much in excess of 5 metres / 16.4 feet, if at all?  

:... individual specimens over 5 metres (16.4 feet) are rarely encountered.<ref name=SaintGirons/> For example, an 18-foot long 128 pound Burmese python found in the wild in Florida in 2013 besting the previous record by more than a foot.<ref>[http://usnews.nbcnews.com/_news/2013/05/20/18379842-man-kills-biggest-burmese-python-ever-in-florida?lite Man kills biggest Burmese python ever in Florida]</ref>

::Something like this would be an acceptable addition, yes.  Even better would be a source for average or median wild size; the skin trade's records may actually be the best bet for that. [[User:HCA|HCA]] ([[User talk:HCA#top|talk]]) 19:06, 7 July 2013 (UTC)

==Cuvier's dwarf caiman==
I didn't know whether [[Cuvier's dwarf caiman]] could be called "Cuvier's wedge head caiman" so I consulted Google and found [http://undergroundreptiles.com/shop/baby-wedgehead-caiman/ this], which gives ''wedge head'' but does not mention ''Cuvier''. However that is not a reliable source and I thought [http://www.reptileforums.co.uk/forums/dwa-species/385722-cuviers-dwarf-caiman-care-sheet.html this one] much better. It gives common names "Dwarf Caiman, Cuvier’s Caiman, Smooth Fronted Caiman, Musky Caiman" and does not mention "Cuvier's wedge head caiman". The [http://reptile-database.reptarium.cz/species?genus=Paleosuchus&species=palpebrosus&search_param=%28%28genus%3D%27Paleosuchus%27%29%28species%3D%27palpebrosus%27%29%29 Reptile Database] does not mention it either. So I propose to change the sentence to include several vernacular names and think you should provide a reference if you want ''wedge head'' to be included. [[User:Cwmhiraeth|Cwmhiraeth]] ([[User talk:Cwmhiraeth|talk]]) 05:46, 10 June 2014 (UTC)

:So "wedge head caiman" seems to be largely confined to the pet trade (where I'm familiar with it), while in the trade "smooth-fronted caiman" refers to trigonatus. This raises the interesting question: if it's used widely but not in anything that meets the "reliable sources" criteria, should it be included?  The problem is that most technical works will simply rely on scientific names (and, indeed, many specialists in the pet trade do too), and less technical RS are extremely uncommon because crocodilian keeping is a rather niche hobby - (there's only one printed book on the topic, AFAIK).

:Because constructal "theory" is fringe at best, useless at worst.  No organismal biomechanics researchers ever use it, and the predictions are so vague as to be totally uninformative. [[User:HCA|HCA]] ([[User talk:HCA#top|talk]]) 17:49, 3 July 2014 (UTC)

I am not sure how familiar you are with publications in Constructal Law and Theory. Have you read the paper <ref>Bejan, A; Marden, James H. (2006). Constructing Animal Locomotion from New Thermodynamics Theory. American Scientist, July–August, Volume 94, Number 4</ref>. On the matter of being called "fringe" it may be a misconception with "new".[[User:Mre env|Mre env]] ([[User talk:Mre env|talk]]) 20:37, 3 July 2014 (UTC)

:You mean this non-peer-review paper with no actual experiments, just hand-waving math and a clear ignorance of the basics of biology?  Like this sentence "And the force output of the muscles of runners, swimmers and fliers conforms with surprisingly little variation to a value of about 60 newtons per kilogram", which is a) incorrect (muscle force scales with cross-section, not volume), and b) incorrectly assumes that because force per cross-sectional area is constant in vertebrates, it's reflective of a mathematical law, when in reality it can and does vary tremendously (by a factor of more than 10x) in invertebrates and the constancy in vertebrates is likely a developmental constraint (probably lack of paramyosin).  The walking section is just as bad - the authors totally ignore elastic energy storage in tendons during walking, a concept which has been around for a good 30+ years at this point, and is known to be a significant factor in cost of transport.
:The figure of a bird's CoM during flight is emblematic of the problem - it's a mathematical fiction done to make your calculations easy, as opposed to actually putting real birds in a real wind tunnel and actually measuring the CoM oscillations.  That the supposed "calculations" include frequently dropping or approximating terms simply means you can tweak it until you get what you want.

:Until the "theory" makes an a-priori prediction with zero data, one that significantly differs from other current theoretical frameworks, and then '''does an actual experiment''', it's not worth talking about.  It's all speculation and post-hoc analysis until and unless you can make a falsifiable prediction and test it experimentally.  And no, "to within an order of magnitude" is not 'close', it's just plain wrong.  If I predict frogs can just 70 feet instead of 7, that's wrong, end of story.

==Advertising, and adding sourced facts==

Hi, I guess you saw that I posted a note on JWCornett's page as he'd been adding refs to books by J.W. Cornett on various pages. Do you think these should all be reverted? I ask because he also added facts and cited them from these sources; a bit flaky, but not purely advertising, I think.

:I lean towards deleting them all; I doubt this is primary research, so we can find alternative references elsewhere, and the listed "publisher" doesn't even have a website, suggesting it's largely self-published.  Additionally, all of the additions I saw were largely excuses to cite the book, which, regardless of the validity of the information, is pretty self-promotional.

I'm already on Animal Anatomy, since it overlaps so much with the Organismal Biomechanics project, though I've not had much time for substantial editing lately.

==Insect flight==

Hi, I was surprised to find that [[Insect flight]] does not have its own article. I note from the article history that [[Insect flight]] was redirected to [[Insect wing]] back in 2012 (with a bit of an edit-war, it seems). This does seem quite a curious choice - a wing is an anatomical structure which (among other things, like advertising and mechanical protection) supports flight, so the topics are logically separate; and if we're prepared to admit that flight is the primary function, then flight would be the natural parent article. The material on flight is quite long (it was over 27,000 bytes at the time of merge), so it would make complete sense as a separate article, where at present it is a remarkably long and technical subsection, covering the mathematics of aerodynamics which can scarcely be argued to be an aspect of anatomy. All in all, I'd instantly split the section off as its own article, but I'd be curious to know the reasoning for the merge, which does not (at first glance) seem to have been discussed much.

::I totally disagree and i find it pretty offensive to have an edit done in good faith being treated as vandalism. If you look at a [https://www.google.com/search?q=%22polarity+therapy%22&ie=utf-8&oe=utf-8 google search on polarity theory] you will see that it is active properly organized form of alternative therapy, see for example [http://www.polaritytherapy.org/ American Polarity Therapy Association]. Stone had degrees in osteopathy, chiropractic and the natural therapies. He developed polarity therapy based on this and published quite a few books on the subject. It is [[WP:POV]] for you to decree that it is "laughable nonsense". Would you say the same for homeopathy, magnet therapy, reflexology etc ?--[[User:Penbat|Penbat]] ([[User talk:Penbat|talk]]) 18:49, 20 September 2015 (UTC)

::I have just started doing a bit of digging on "polarity therapy" and [http://ict.sagepub.com/content/10/1/27.short this academic paper] suggests that polarity therapy helps with cancer-related fatigue.--[[User:Penbat|Penbat]] ([[User talk:Penbat|talk]]) 19:09, 20 September 2015 (UTC)

::Polarity therapy is at least a step ahead of, for example, [[homeopathy]], [[magnet therapy]], [[reflexology]] which as far as I am aware have absolutely no credible academic support at all but still exist on Wikipedia which undermines your "laughable nonsense has no place on WP" stance.--[[User:Penbat|Penbat]] ([[User talk:Penbat|talk]]) 19:29, 20 September 2015 (UTC)

:First, it's "alternative therapy"; if it was proven, it wouldn't be "alternative", would it?  Your cited study is a mere pilot study, which fails to use double-blind methods, fails to placebo-match, and has a very small sample size.  Until and unless you can show me a double-blind, placebo-controlled study with a sample size of several hundred, it's nothing but quackery with no plausible physiological mechanism.  Or perhaps direct physical measurements of this "energy" it claims to "balance".  You can make it a page elsewhere if you must, but it no more belongs on "squatting" than magic crystals should be featured on the [[quartz]] page.  It falls firmly under [[WP:FRINGE]], and if you disagree, I'm sure you'll have no problem producing the sorts of evidence I requested above. [[User:HCA|HCA]] ([[User talk:HCA#top|talk]]) 20:54, 20 September 2015 (UTC)

::The study I mentioned above was a randomized controlled study. It is most likely impossible to do double-blind trials on polarity therapy as it involves physical manipulation not taking a tablet which can easily be interchanged with a placebo. I have also already mentioned [[homeopathy]], [[magnet therapy]], [[reflexology]] which have no known plausible physiological action but that is not entirely the point. Would you call homeopathy, magnet therapy, reflexology [[WP:FRINGE]]? What about [[acupuncture]] which also has no known plausible physiological mechanism. The scientific support for acupuncture exists for some conditions but is weak, although it is still in many cases used by state health authorities such as the NHS in the UK as treatment. Some UK state NHS GPs refer their patients to homeopaths with public funding. Where exactly do you draw the line with your [[WP:FRINGE]]? Including "polarity therapy" in the squatting article makes no claims either way about its effectiveness in general, it is only mentioned in the context of squatting. The cite you have used to state that polarity therapy is quackery is based on one person's opinion based on no cites more recent than 2002. It is not a definitive view. Whether or not something has any known plausible physiological mechanism is not a reason in itself for dismissing something as worthless and unworthy for scientific study, as for example, acupuncture. Polarity therapy is at least considered worthy of scientific study.--[[User:Penbat|Penbat]] ([[User talk:Penbat|talk]]) 19:36, 21 September 2015 (UTC)

:::Yes, every single one of those is [[WP:FRINGE]], only because there's no official designation of WP:BULLSHIT.  Lack of a mechanism is absolutely a reason for dismissal - otherwise I can claim the NIH should give me a grant to study whether cancer patient outcomes can be predicted by observing the motions of turtles 300 miles away.  Even if I found a correlation, it's much, much more likely to be a false positive (type 1 error) than real, because of the lack of mechanism.  That various "health authorities" have either been suckered by this nonsense or capitulated to their massive lobbying efforts (turns out selling pure water and lies has low overhead and high profits) is irrelevant.  And if they can't design a placebo, they aren't trying hard enough - consider just having people do squats, without any energy nonsense, as well as leg presses, to remove the potential effect of light exercise and postural changes.  I see no reason your study doesn't simply show the effects of a small bit of exercise.
:::My criteria for "not fringe" is a) a statistically significant result on a large, double-blind randomized test, preferably shown in repeated studies and subject to meta-analysis to correct for Type 1 & 2 errors and b) a plausible physiological mechanism.  My bullshit detector sounds a huge alarm when I see a) claims that some method can cure a huge host of physiologically unrelated ailments (cancer, viral infections, arthritis, depression), b) relies on unknown and largely mystical mechanisms ("energy"/chi, chakras, "water memory"), c) is accompanied by claims of "supression" by "the medical establishment", and/or d) claims to have originated from "ancient traditions" (either directly or because the creator had an epic journey to go learn them).  But I'm willing to be proven wrong: see my "not fringe" criteria.
:::Frankly, the reason I labeled the edit as vandalism is that I'm used to advocates of assorted crackpot theories showing up on various pages to promote or at least increase visibility of their pet delusion, whether that's creationism, Aquatic Ape hypothesis, or alternative medicine.

== Gait Analysis ==

Hey HCA!

I see you undid my revisions on [[Gait Analysis]]. I understand if you are against chiropractic and OMT, everyone is entitled to their own beliefs, but if I were to re-include my addition with sources would that constitute a good edit? Just because it is your belief that chiropractic and OMT is a pseudoscience doesn't mean there isn't scientific data about the fundamentals of these practices that have proven results. It's a topic for another time, but chiropractic of the last 20 years is nothing like the docs who have been in practice longer than that. We are very focused on biomechanics and restoring active and passive ranges of motion, and gait analysis is one of the key systems of diagnosis DCs and DOs employ. There are studies that show the positive effects of chiropractic and osteopathic manipulations on the sacro-iliac joints to improve instances of dyskinesia in the pelvis. If I were to include them in a future edit, undoubtedly they should be allowed? In the meantime I have updated the page again. I have included four different studies that show improvement in gait after OMT or adjusting, so certainly these will suffice as good sources that show DCs and DOs utilize gait analysis heavily (regardless of whether or not you agree with them as professions in the first place).

Hi HCA,

I'm curious why you reverted the TaxonBar from the [[Coelacanth]] page? I think having the links to standard taxonomic identifiers is useful for linking observations about species together.

== Largest bird that can hover ==

This is in response to a reversion you made in the wiki article about birds hovering.

Video of a white tailed kite performing at a show, hovering in still air during a demonstration, despite the relatively heavy tether attached to it's legs (the demonstration starts at 1:10 into the video):

http://www.youtube.com/watch?v=JnbndA0Rjfg

I live in southern California and fly radio control gliders as a hobby. One of the locations I visit is Kite Hill, the location and nearby community named after the white tailed Kite. I have personally witnessed a Kite hovering against a slight tailwind (so technically hovering and flying backwards) for over 20 seconds. Normally the wind comes from the south, blowing up the hill, but in this case, the wind was coming from the north due to a "Santa Ana" condition. I assume that Kite was used to being oriented downhill, despite the tailwind condition. In near zero wind conditions, I've seen Kites hover for over 30 seconds. 

I've also seen Osprey's at nearby Laguna Beach, also hovering in near zero wind conditions (no perceptible cross wind or updraft), but they normally only hover for a few seconds before diving. Unlike a Kite, the Ospreys apparently sight fish near the ocean surface during normal flight or partial hover, and my guess is they hover only long enough to get a fix on the fish and setup a dive. It appears they could hover for longer, as they have more than enough energy to dive underwater, use their wings to resurface out of the water and either fly away with a fish or fly back to their hunting altitude which is around 80 feet at this particular location.

In both cases, but more impressive with the Kites due to their longer hover times is that since they target a ground object during a hover, they remain nearly motionless relative to the ground despite any wind. [[User:Rcgldr|Rcgldr]] ([[User talk:Rcgldr|talk]]) 07:44, 8 April 2017 (UTC)

==[[Flying and gliding animals]]==

Hi, I'm working on a whole lot of evolution articles (and trying to get the more important ones to Good Article status, quite tricky with the historical ones as hardly anyone wants to review them). [[Flying and gliding animals]] is potentially quite an important article — you stated that "The evolution of flight is one of the most striking and demanding in animal evolution, and has attracted the attention of many prominent scientists and generated many theories", and added that they fossilize poorly and infrequently. I'd like to improve the referencing for the article, and wondered if you could suggest suitable sources, for instance for the [[Flying and gliding animals#Evolution and ecology|Evolution and ecology]] and [[Flying and gliding animals#Biomechanics|Biomechanics]] sections? It would be much appreciated. [[User:Chiswick Chap|Chiswick Chap]] ([[User talk:Chiswick Chap|talk]]) 03:07, 31 October 2017 (UTC)
:For more accessible sources, http://www.ucmp.berkeley.edu/vertebrates/flight/enter.html is a good overview.  For more detailed sources and papers, http://hs.umt.edu/dbs/flightlab/default.php https://berkeleyflightlab.org/ http://combeslab.ucdavis.edu/ and http://www.brown.edu/Departments/EEB/EML/ are all excellent.

== [[Constructal law]] ==

Hope you don't mind a comment here, but I've just read that article again and I felt the need to share my conclusion with someone - it's complete and utter bullshit from start to finish, isn't it? I can see why there might have been very little academic critique of it - because most people probably consider it as just too stupid to spend valuable time on. [[User:Boing! said Zebedee|Boing! said Zebedee]] ([[User talk:Boing! said Zebedee|talk]]) 17:28, 8 December 2017 (UTC)
:Absolutely.  It's vague to the point of being Rorschach Test, overgeneralizes an occasional phenomenon to universality, has no clear predictions (beyond "increases"), has never been rigorously put through falsification tests, and makes asinine assumptions about "optimization" and "continual progress" about biological evolution.  I first encountered it a decade ago, back when I was an MS student, and it smelled like horseshit even then. [[User:HCA|HCA]] ([[User talk:HCA#top|talk]]) 18:18, 8 December 2017 (UTC)
::Is it just me, or is the following self-contradictory?
:::"''The lightning bolts that flash across the sky generate a tree-like structure because this is a good design for moving a current (electricity) from an area (the cloud) to a point (a church steeple or another cloud). The circulatory and nervous systems of biological creatures generate a similar tree-like design because they too are moving currents from a point to an area and from an area to a point.''"
::For the analogy to hold, a lightning bolt would surely need to start in a dispersed pattern in the cloud and converge on to the point at the church steeple - ie upside down from the way it actually is. [[User:Boing! said Zebedee|Boing! said Zebedee]] ([[User talk:Boing! said Zebedee|talk]]) 18:35, 8 December 2017 (UTC)
:::So from what I've read, there's actually some real physical basis - in systems where flow rate is modulated by some resistance to flow, spontaneous patterns will generally follow the path of least resistance, whether electrical current or fluid flow, and will often "prune" or "redirect" automatically when lower-resistance paths become available.  That much is uncontroversial.  The problem is proclaiming this as a "universal law of nature" rather than just an interesting property of some systems, and over-enthusiastically applying to biology based on false assumptions about how evolution works. [[User:HCA|HCA]] ([[User talk:HCA#top|talk]]) 18:56, 8 December 2017 (UTC)
::::Yes, and his "universal" law often suggests the opposite to what actually happens. If biology was compelled to follow the path of least resistance by a law of physics, the giraffe wouldn't have such an apparently silly laryngeal nerve. [[User:Boing! said Zebedee|Boing! said Zebedee]] ([[User talk:Boing! said Zebedee|talk]]) 19:10, 8 December 2017 (UTC)
:::::To the extent that the "constructal law" can even be formulated as an engineering principle, it [https://doi.org/10.1016/j.enconman.2007.05.023 apparently doesn't work]. [[User:XOR&#39;easter|XOR&#39;easter]] ([[User talk:XOR&#39;easter|talk]]) 17:35, 9 December 2017 (UTC)

== Coelacanth: former belief they were transitional to tetrapods ==
I added a citation needed for the specific statement that, prior to 2013 DNA testing, coelacanths were believed to be transitional between fish and land animals (i.e. tetrapods), and removed the citation needed for the less specific statement coelacanths were believed to be transitional at some point in the past.  This change was reverted.  Why does the more specific (dated) statement in the DNA section not require a citation, but the less specific statement require one?  If the specific statement about “prior to 2013” had a citation, we would not need another citation saying that coelacanths were once considered transitional. https://en.wikipedia.org/enwiki/w/index.php?title=Coelacanth&type=revision&diff=818436729&oldid=818346377  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/2602:252:D44:78F:60D4:1C6E:ADE0:3AA5|2602:252:D44:78F:60D4:1C6E:ADE0:3AA5]] ([[User talk:2602:252:D44:78F:60D4:1C6E:ADE0:3AA5#top|talk]]) 01:33, 6 January 2018 (UTC)</small> <!--Autosigned by SineBot-->
