I have been debating the following topic with a friend.
- She argues that humans do not descend from chimpanzees or orang-utans, because if we did, such animals would share the same cognitive thinking that humans have.
- I argue that we do descend from that such animals, and that a high protein diet has allowed early humans to develop a better memory, intelligence, and other mental processes.
Questions
- What is the the real origin of human intelligence?
- If non-human animals do have intelligence too, why is their intelligence not as advanced as humans?
