Objection to endorsement of recapitulation theory

[edit]

Recapitulation theory is not widely relied upon. The statement which suggests otherwise should be rephrased or removed. —Preceding unsigned comment added by 204.140.141.100 (talk) 01:00, 25 March 2011 (UTC)[reply]

It looks like most of the citations are from http://www.nature.com/nature/journal/v456/n7220/full/nature07309.html. There is a paywall there, but the abstract makes no mention of Recapitulation Theory. I don't even see how Recapitulation Theory ties in here, honestly. I'll do my best to clean it up, but I am not a clever man. — Preceding unsigned comment added by 99.41.216.89 (talk) 18:46, 14 March 2012 (UTC)[reply]

merge

[edit]

Isn't this title just another phrase for "gastrulation"? I was surprised to see that term wasn't used on this page, so perhaps it was just an unintended duplication and should be merged? Cesiumfrog (talk) 01:45, 2 November 2012 (UTC)[reply]

Human uniqueness

[edit]

"Humans, unlike the protostomes and other deuterostomes, already have a formed gut tube at the time of formation of the mouth and anus."

Is our species really this embryologically unique? —unsigned

I'm not sure it necessarily requires humans to be unique in this respect, since this stage of development obviously hasn't been studied for every single deuterostome. It could vary widely. But humans certainly are unique in many other ways, so why would a unique gastrulation schedule be so hard to believe? Aminomancer (talk) 09:44, 6 October 2024 (UTC)[reply]
