A fact from Arthropod head problem appeared on Wikipedia's Main Page in the Did you know column on 16 July 2007. The text of the entry was as follows:

Did you know... that despite over a hundred years of scientific study, fierce debate still rages about how arthropods' heads are constructed?

A record of the entry may be seen at Wikipedia:Recent additions/2007/July.

Diagrams

The fossil evidence and different theories of Cambrian arthropod head segmentation sections could really use some diagrams. --Savant13 (talk) 18:48, 2 May 2008 (UTC)[reply]

Reference to MADS-box genes in molecular development section

An edit (2, to be precise) by user MartinJ12033 at 07:05, 29 April 2008 and 07:07, 29 April 2008 inserted some language into the section on molecular development which is grammatically incorrect, refers to MADS-box genes - but talks about them in conjunction with sexual expression in plants - and is generally incomprehensible.

I'm not knowledgeable in this area; but since MartinJ12033 appears never to have made any other edits on Wikipedia, I doubt he will be available to ask him what he actually meant. Would anyone object to me changing that section back to its state before that edit? It hasn't changed since MartinJ12033's edit.

The version I can understand: "The arthropod head problem has been tackled in three main ways in this regard, first by using genetic segmental markers to probe the obscure region in front of the mouth, especially in insects; second by looking at Hox gene expression patterns to detect patterns of homology between different arthropods; and third, by studying gene expression in particular features (especially the labrum) to determine its appendiculate or other status."

The version I can't: "The arthropod head problem has been tackled in three main ways in this regard, first by using genetic segmental markers to probe the obscure region in front of the mouth, especially in insects; second by Hox gene, showing evidence of being evovled in the Paleozoic era, have the ability to express patterns of homology between different arthrods. Just as Hox genes express patterns, Mads-box genes have the potential to initiate an important role in the integration of sexual expression time pathways in plants." Third, by studying gene expression in particular features (especially the labrum) to determine its appendiculate or other status." —Preceding unsigned comment added by Peace Makes Plenty (talk • contribs) 12:02, 10 February 2009 (UTC)[reply]

The article is not clear

Although I read it through I couldn't understand what is the "Arthropod head problem" acctually. It should be clear from the first section and it isn't. Idvash (talk) 14:53, 7 February 2012 (UTC)[reply]
