Maria wondered if different colors of plastic wrap affected the time for bread to mold. She wrapped a slice of bread in clear plastic wrap. Before wrapping the bread she placed 5ml of water in the center of
the bread. She repeated the process with a slice of bread using red plastic wrap & a slice of bread using
blue plastic wrap. The bread came from the center of the same loaf. In each case she used the same
amount of water and the same brand of plastic wrap. She wrapped the different slices of bread in the
same way.

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?
