What makes a primate? Forward-facing eyes for depth perception, a post-orbital bar or complete post-orbital closure (bony ring or full enclosure behind the eye), broad-based posterior teeth, diverging thumbs and big toes, and flat nails instead of claws. These shared traits define our entire primate family. 🐒
Key facts claimed:
- Primates have forward-facing eyes for depth perception
- Primates have a post-orbital bar (strepsirrhines) or complete post-orbital closure (haplorhines) — not all primates have fully encased eye sockets
- Primates have broad-based posterior teeth
- Primates have diverging thumbs and big toes, with friction pads on hands and feet
- Primates have nails instead of claws — flattened distal digits on fingers and toes
