 got us this far because if you think about our lives on the african plains two million years ago our ancestors were called homo erectus they looked some most mostly like us um you know they because of climate change and climate shifts they were forced out of the trees where our ape ancestors had lived and they needed to survive and they certainly weren't the most physical i mean you had lions out there i mean they they had good saber-toothed cats so we weren't going to be the strongest we weren't at the top of the food chain
