Science with Simon Pollard

From Nine To Noon, 11:50 am on 29 June 2011

About half of all female primates conceal ovulation to make it unlikely that males will know when they are fertile. Among the apes, humans and orangutans conceal ovulation while our closest living relative, the chimpanzee, advertise it loudly and proudly. Simon talks about some current ideas about why concealed ovulation evolved and what old school anthropologists could have learned from gibbons.
