Although our brains were getting bigger progressively, around 70,000 years ago they plateaued, and have been shrinking ever since. John Hawks, an anthropologist at the University of Wisconsin, explains how, over the last 20,000 years alone, human brains have shrunk from 1,500 cubic centimeters (cc) to 1,350 cc, roughly the size of a tennis ball.
Except this requires extrapolating brain volume from the skull , which probably inaccurate compared to modern day MRIs. So i would take this claim that brains are shrinking with some skepticism.
