Robot helps study how first land animals moved 360 million years ago
When early terrestrial animals began moving about on mud and sand 360 million years ago, the powerful tails they used as fish may have been more important than scientists previously realized. That’s one conclusion from a new study of African mudskipper fish and a robot modeled on the animal. Animals analogous to the mudskipper would have used modified fins to move around on flat surfaces, but for […]
