🐸 Xenopus laevis 💚 The frog that shaped modern developmental biology! ✨ Xenopus embryos have revealed how the body axis forms, cells choose their fate, and tissues self-organize during early development 📹 Video by Bioquest Sudio and Xenbase #ModelMonday #DevBio

Ascidians (Ciona intestinalis)🪸Our distant chordate cousins! 🌊 Simple sea squirts that reveal how vertebrate body plans evolved 🧬 A key model for notochord formation, neural induction, and cell lineage mapping 📸 Video by MBL Embryology 2019 #ModelMonday #DevBio #EvoDevo
