Recall the mechanisms of genetic evolution discussed in the previous chapter. What is the relationship between gene flow and the existence of clines between human populations?
A) Gene flow increases the genetic isolation of neighboring groups, resulting in discrete populational genetic differences instead of clines.
B) There is no relationship between gene flow and clines.
C) Gene flow, the exchange of genetic material across populations, results in clines, which are gradual shifts in gene frequencies between neighboring groups.
D) Clines accelerate gene flow and genetic change due to chance.
E) Gene flow causes abrupt differences in gene frequencies between neighboring groups.

Gene flow can lead to gradual shifts in gene frequencies between neighboring populations, resulting in clines. This is because gene flow allows for the exchange of genetic material between populations, which can result in the diffusion of alleles and gradual changes in gene frequencies over time. Therefore, the existence of clines between human populations is related to the process of gene flow.
