The recent discovery of a 13 million-year-old fossil infant ape skull has offered a rare glimpse of what the common ancestor of all living apes and humans may have looked like. The fossil, nicknamed “Alesi,” belongs to a newly named species called Nyanzapithecus alesi. Alesi was discovered in a desolate region of Kenya by John Ekusi, a member of Dr. Isaiah Nengo’s research team. In this talk, Dr. Nengo will share the story of finding this rare fossil and discuss the secrets that cutting-edge technology has uncovered about the life of this ancient infant.
