BIO153H5 Lecture Notes - Lecture 15: Homo Naledi, Hertz, Bipedalism
Document Summary
We have a pretty good idea about human phylogeny. Make high frequency sounds (90 kilohertz) they (cid:272)a(cid:374) hear ea(cid:272)h other, (cid:271)ut other orga(cid:374)is(cid:373)s (cid:272)a(cid:374)"t hear them (whether predator or prey) What"s the differe(cid:374)(cid:272)e (cid:271)et(cid:449)ee(cid:374) ho(cid:373)i(cid:374)i(cid:374) a(cid:374)d ho(cid:373)i(cid:374)id: hominins are all species that are more closely related to homo sapiens than chimps and any other large primates and apes. They are describing the same thing, but hominin is the more recently accepted term. All we have is a range of species and when they existed. We are still not sure ho(cid:449) they"re all related to ea(cid:272)h other and how they fit together with each other. Estimated to be about 3. 3 million years old. Had (cid:862)tree-feet(cid:863) that (cid:449)ere hu(cid:373)a(cid:374)-like, (cid:271)ut it"s shoulder blades (and related structures) resembled that of gorillas. Might have walked on the ground like humans do, but also have characteristics that were much more indicative of living in trees (hanging from your arms and swinging from tree branches)
