An anthropologist compares the remains of homo neaderthalensis to earlier hominid species, like homo habilis, and to the contemporary and later species homo sapiens. he believes that homo neanderthalensis were the first hominids to bury their dead. what would make this conclusion incorrect?

a. finding a fossil of homo habilis beneath fossils of homo neanderthalensis
b. finding fossils of homo neanderthalensis skeletons in isolation
c. finding burial sites of modern homo sapiens in the same region as homo neanderthalensis fossils
d. finding burial sites of homo habilis on different continents

burial sites containing bones of any of the previous hominid species would disprove this conclusion.

hope this

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
