I read in the "Getting to the bottom of anal evolution, 2015" by Andreas Hejnol and José M.Martín-Durán the following sentence:
Bilaterians differ from non-bilaterian groups in that they gastrulate at the vegetal pole and not at the animal pole (Martindale and Hejnol, 2009)
I did try to read the article is names as the source of this statement, but it's far too technical for me. Can somebody with has more biological knowledge take a look and add this information to this (and maybe also the bilatarian) page, seems to me quite a relevant difference if correct. It's allready 13 years old, so there might be a lot more on this in later publications. Codiv (talk) 15:31, 11 August 2022 (UTC)[reply]
Im not sure we know what actually happens. There's still some uncertainty on pages like gastrulation. And the dividing line im used to seeing is not bilaterians:others, but deuterostomes:protostomes. Both of these groups are bilaterians. —Soap—19:17, 25 November 2024 (UTC)[reply]
