Document Summary
The genus homo: traditional hallmark of homo: brain size, other traits, 1. Reorganization and expansion of the human brain: globular brain shape, even if the sign is not significant, expansion not as dramatic in the beginning as previously thought, h. naledi, 2. Scavenging and tool making: chronospecies, h. habilis > h. erectus > h. sapiens, anagenic changes, few fossils, new fossils, dmanisi, naledi, new definition of homo. *history of when fossils were found plays a big role in determining human ancestry- made a mess. *criteria is changing as new fossils are found. Curved phalanges: derived features of hand, thumb to finger ration, precision grip, evidence to look for tools, 2. Funnel shaped rib cage, smaller vertebral bodies: more arm mobility, 3. Brain structure and diet: australopithecines insects, termites, marrow, primarily vegetarian, relied on skull/teeth, megadontia, homo, omnivores, meat in diet; higher instances, relied on tools b/c teeth a lot smaller teeth smaller brain bigger; what happened first.
