Evo-Devo (Despacito Biology Parody) | A Capella Science

The video is a musical parody that explains evolutionary developmental biology, describing how single cells differentiate into complex organisms through gene regulation, signaling pathways, and modular development. It highlights concepts such as genetic switches, developmental networks, and the role of key genes like Hedgehog, illustrating how small changes in regulation can lead to major morphological differences across species.
