Biletarians gastrulate at vegetal pole

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]
