Why are our brains shrinking?
As promised, here is the first post in our “The Student of Life” series. This essay, focusing on the fascinating subject of the shrinkage of our brain over the last 70,000 years, was masterfully penned by USF student Savannah Robison during the Fall 2017 semester of BIOL100. It is a wonderful example of student…
