The xenacoelomorph gonopore is homologous to the bilaterian anus

2025-02-10

Abstract excerpt

The bilaterian through gut with an anal opening is a key invention in animals, since it facilitates effective food processing, which allows animals to grow to a larger body size. However, because non-bilaterian animals lack a through gut, the evolution of anus is still debated. The formation of bilaterian hindgut is governed by the spatial expression of several transcription factors (e.g. Caudal and Brachyury) und...
