modern humans

movement into colder climates

only appeared after the "Cambrian explosion" around 500 million years ago

overlapping marks on the bones

Homo erectus lived during which epoch

pleistocene

Rick Potts suggests that the impetus for the transition to humans was

rapidly fluctuating environments

The deeper a layer of strata is the older it is defines the idea of

relative dating

Archaic Homo sapiens exhibit anatomy that is

remarkably similar to modern humans

The complex S-curve of the hominid vertebral column functions to

reposition the cranium to the body's midline

required extensive prior planning

shows a close ancestry with modern Asian humans

The cranial capacities of archaic Homo sapiens were on average

smaller than those of modern humans or in the middle of the range of modern humans

The modern human population that shares the most DNA with Neanderthals comes from

southern Europe

Evidence from Neanderthal tools and genetics suggest

speech and language like ours

The discovery of Homo Floresiensis shows
