We all learned in science class that human's have big ol' brains, and that the size of our brains is responsible for all of the fancy things humans have achieved in our relatively short stint here on Earth. However, new research into the evolution of the brain "cases" of Homo sapiens (simply put, the inside of the skull) suggests that the size of our brains might not have been the most important factor in getting us where we are today.
Homo sapiens had quite large brains even as far back as 300,000 years ago. However, it took a long time for the elongated, flatter brains that were present in the earliest examples of our species to evolve into the rounder, globe-shaped brains we have today. A new paper published in Science Advances attempts to narrow down the timeframe of when our brains changed, and researchers have discovered that its changing shape may have been the key factor in sparking human ingenuity.
