Prior to the Work of Li and Others,scientists Had Estimated

Prior to the work of Li and others,scientists had estimated that Homo sapiens had lived in a limited African range at about 40,000 years ago.Migration took subpopulations away from this original area.Although speciation did not occur in this time,

A) DNA sequence data indicated that Homo sapiens subpopulations showed little natural selection of genotypes and phenotypes.
B) None of the answer choices are correct.
C) DNA sequence data indicated that gradualism dominated the evolutionary history of humans in the last 40,000 years.
D) DNA sequence data showed that people from Africa, Asia, and Europe actively interbred and maintained a constant gene pool.
E) DNA sequence data indicated a rapid adaptive radiation, leading to microevolution of the gene pools.
