Which data would be the best evidence to support the claim that natural selection was still occurring in human populations

1 answer

One possible piece of evidence to support the claim that natural selection is still occurring in human populations would be data showing changes in allele frequencies over time in response to certain environmental pressures. For example, if a certain genetic variant conferring resistance to a particular disease becomes more prevalent in a population over successive generations, this would suggest that natural selection is at play.

Another piece of evidence could be data showing differences in reproductive success among individuals with different genetic traits. If individuals with certain traits are more likely to survive and reproduce, passing on those traits to future generations, this would indicate that natural selection is shaping the genetic makeup of the population.

Overall, any data showing changes in genetic diversity and allele frequencies in human populations in response to environmental pressures would be strong evidence for ongoing natural selection.
