Yes. Also, most every mammals other than whales _still_ have fur (seals, sea lions, otters, etc), so it's not clear that hairlessness has strong selection press

- scotty79 5y agoWhen thinking about what water humans had a contact with at one time you should rather think of hippos not otters. Shalow, warm, maybe even not salty water? It must have been significant food source if we have very specific adaptation to gipping something in water.
- Scaevolus 5y agoPruney fingers are a general primate adaptation, and likely have more to do with not slipping from trees when it rains than any serious aquatic phase.
- scotty79 5y agoNot that general. The only other species I can find mentioned to have pruney fingers are macaque monkeys. And we are unsure if that's a remnant of common ancestor or a parallel evolution.
