TED-Ed: Claws vs. nails | Matthew Borths

The video explores the evolutionary journey from claws to nails, highlighting their shared keratin composition and differences in shape due to bone structure. Nails evolved from claws, offering primates advantages in dexterity and grip, crucial for survival in forest canopies. The video also discusses unexpected uses of claws and nails in various animals, emphasizing their diverse roles in the animal kingdom.
