Photo (and concept) of the Day: January 12, 2016; faces everywhere
"As soon as the infant can see, it recognizes faces, and we now know that skill is hardwired in our brains. Those infants who a million years ago were unable to recognize a face smiled back less, were less likely to win the hearts of their parents, and less likely to prosper. These days, nearly every infant is quick to identify a human face, and to respond with a goony grin."
