In the winter, food is scarce in the tundra. whimbrels are shorebirds that have nesting grounds in the canadian tundra. every spring, they can be seen along the southeastern coast of the united states. there, they feast on small crabs on their way back to their northern nesting grounds. scientists have tracked the migration routes of these birds, which are shown on the map.

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
