Why is there less genetic variation among humans than among other species? this statement is debatible

Explanation:

In regard to the options, species may exhibit less variation when their branches represent the youngest lineages, suffer loss of genetic variation during evolution (i. e., genetic bottleneck) or show low mutation rates
