“You’re theory that squirrels are similar to primates is pretty accurate. The first primate-like mammals are referred to as proto-primates. They were roughly similar to squirrels and tree shrews in size and appearance. It is a good example of convergent evolution where an arboreal existence exerts natural selection pressures to evolve similar physical attributes, intelligence, and behaviors.”
Does the fossil record support this?
Yes, the fossil record does support this. Early primates evolved from a squirrel-like ancestor. I did not say that primates evolved from squirrels.
