How does his observations on Finches prove that we have ape like ancestors ?
I wish I was a robot.
Whether we descend from apes or not, we are clearly animals- mammals. Animals exhibit emotions frequently.
His finch observations merely showed the dynamics whereby over millions of years, organisms adapt to survive better in their surroundings. Why wouldn't our brain functions adapt just the same way our physical bodies did? Eg. We lost our tails and began to walk on two legs.
It's hard to imagine but, perhaps our very distant ancestors didn't have the range of emotions we have now. Who knows?
Animals can clearly exhibit aggression, joy, greed, jealousy, sympathy, grief, love even. Our reasoning and awareness developments are (debatably) more advanced but, how are we so different to animals in our raw emotions?
