That is incorrect, dolphins are unlikely to evolve hands and humanoids evolved hands before they became intelligent (probably to grab branches). It was very lucky that a good brain evolved in a body that already had hands.
- cutemonster 2y ago> very lucky that a good brain evolved in a body that already had hands. The other way around: hands adds evolutionary pressure towards becoming more intelligent. (The ones that understand how to use their hands and tools better...)
- DoctorOetker 2y agoThe lack of knowledge. Dolphins do have organs with which they pick up things like rocks or shells and they are able to give them to each other. They use their sexual organs as "hands"! Both males and females. In the tree of life brains are correlated much more strongly with locomotion than with hands. The moment you need to do (inverse) kinematics to plan an immediate action, and to plan sequences of motions, and to plan a hunting or fleeing strategy, is what put pressure to evolve brains, static lifeforms can be very complex and have complicated genomes, but brains you wont find in them...
