Symmetry isn't always good. When we look at human faces, the most symmetrical, where one half is mirrored to the other, are less attractive than faces that show some distinction. And it isn't just culture. A study in brains found that too much symmetry is also bad. Fish that have symmetric brains show defects in processing information about sights and smells, according to a new paper in Current Biology. It's widely believed that the left and right sides of the brain have slightly different roles in cognition and in regulating behavior, but whether or not these asymmetries actually matter for the efficient functioning of the brain is unknown read more
