What seems to be wrong with the controversy section? Lizz612 16:08, 22 August 2007 (UTC)
The Richardson article refered to which questions the validity of the phayngula stage is published in a peer reviewed journal. It's certainly not creationist propaganda. However, there are some serious critics of this work. PZ Myers, author of the blog pharyngula has some strong arguments against Richardson's work. These are linked to in external links on the page. Perhaps balance would be clearer if these links were moved into the Controversy section? Djs93 ( talk) 17:34, 2 January 2008 (UTC)
I am considering developing this page further as part of an educational assignment in Fall of 2013. If someone else is also working on this, please send me a message and let me know soon, so we donʼt duplicate initial efforts in page development Pitpeelorchard ( talk) 03:17, 7 October 2013 (UTC)
This article mentions the Hourglass Model which says that "embryogenesis diverges more extensively in the early and late stages than the middle stage". This should be elaborated. What about this step in embyrogenesis that causes the organisms to have so much in common. An article on scienceblogs.com gives some detail on why this is so. It says that at the pharyngula point, "global interactions dominate—molecules are working as gradients or chains of reactions across the whole of the embryo to stake out the general body plan." Genes are being activated in such a way that the whole animal topography is well conserved. The genes involved in this processes would be good to discuss as well. http://scienceblogs.com/pharyngula/2007/05/08/basics-the-pharyngula-stage/ Pitpeelorchard ( talk) 03:41, 7 October 2013 (UTC)
