Question

from the interactive video: great transitions
the conclusion that the common ancestor of modern chips and modern humans lived around 7 million years ago is supported by which of the following lines of evidence?
stone tools have been found that date back to 7 million years
scientists estimate that it would take about 7 million years for chips to evolve into humans
scientists estimate it would take about 7 million years to go from an early hominid brain size to human brain size
a nalysis of modern human and modern chimpanzee protein and dna suggests that their lineages diverged about 7 million years ago

Explanation:

Analysis of modern human and modern chimpanzee protein and DNA is a reliable method to determine the divergence time of their lineages. Stone tools date back to a later period. Estimating evolution from chips to humans is incorrect as humans did not evolve from chips. Estimating based on brain - size evolution is not as direct as genetic analysis.

Answer:

analysis of modern human and modern chimpanzee protein and DNA suggests that their lineages diverged about 7 million years ago
