Evolutionary biology Low‑importance This article is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, and evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

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

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

"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?
