Why are primates social in the short term. Why do primates have long growth and development periods? non-human primates apparently only recognize matrilineal descent While individual primates are frequently hypothesized to form enduring social bonds with conspecifics, recent studies suggest that relationships are labile, with animals interacting only over short periods to satisfy their immediate needs.
