2. The simplified evolutionary tree and the expanded one both show that at some point in time the Chimpanzees and Bonobos evolved from a common ancestor not shared by humans, but before that there was a common ancestor shared by all three lineagesāTrue or False?
3. The common ancestor of Humans, Chimpanzees, and Bonobos produced generation after generation of descendants, some of which evolved into humans. Although not fully shown in the diagram, that common ancestor had to have also produced generation after generation of descendants some of which evolved into the common ancestor of Chimpanzees and BonobosāTrue or False?
4. Chimpanzees, bonobos, and gorillas donāt regularly stand upright or walk on two feet alone. Their hands and feet touch the ground for walking on āall foursā. The common ancestor of Chimpanzees, Bonobos and Humans produced some descendants that evolved the ability to walk and run using only 2 legs after chimpanzees and bonobos evolved as distinct speciesāTrue or False?
5. Again look at the evolutionary tree of human phylogeny shown above. On a geological time scale, shortly after chimpanzees and bonobos came into existence as separate species, humans came into existence as a distinct species (called, Home sapiens). According to some researchers, the fact that humans evolved social and creative abilities far more complex than chimpanzees and bonobos, suggested that the evolution of tool-making abilities started in primates after chimpanzees and bonobos came into existence. That suggestion or idea is consistent with the ancestral history shown in this diagramāTrue or False?
