Question
A recent news article reports on findings from a dig in Mesopotamia. The researchers report that skeletal populations indicate a decline in stature and likely overall health at this period in time. This reminds you of another study you have read about, the populations of St. Catherines Island. What could be the reasons for the changes in skeletons?a. Health and stature declined with a transition to hunting and gathering.
b. Health and stature declined with the adoption of agriculture.
c. Health and stature declined with the Industrial Revolution.
d. Health and stature declined because of an outbreak of an avian virus.
