Document Summary
Assumed before we understood dna evidence that these were all grouped. Once we understood evolutionary relationships based on dna we understood. Hominids refers to all the great apes. Nodes represent the common ancestors of the branches on the tree. We know the last common ancestor between apes and chimps 8-10 mya. We know the last common ancestors between chimps and humans 6-8 mya. Everything on the branch after the chimp human common ancestor is what we refer to when we say hominins. Evolutionary trends in the hominin eventually led to us modern humans. Similar dna in humans and chimps but very different regulatory genes in the nervous system, brain development, and speech that have changed over the past 6 -8 million years that have caused humans and chimps to be different. Technology we use technology in a more sophisticated way than other primates. Adaptations towards walking on two legs adaptations for bipedal locomotion.
