Refer to the two box plots below. The first box plot represents a sample of skulls of male Egyptians from about 4000 BCE, whereas the second box plot represents a sample of male Egyptian skulls from about 150 CE (in mm, based on data from Ancient Races of the Thebaid by Thomson and Randall-Maciver). A shift in head sizes would suggest some societal changes, such as interbreeding with other cultures. By comparing the two box plots, is there a shift in the maximum skull breadth? Explain.
