It's fundamental premise, unchallenged for 60 years, holds that males gain evolutionary advantage from multiple sex partners while females do not. Researchers have reproduced the conditions of Bateman's original experiments and have determined his assumption and methods were flawed at multiple levels and he missed the mark completely. Females and their offspring benefit even more from multiple partners in mating strategies than do males."
Men occasionally stumble over the truth, but most of them pick themselves
up and hurry off as if nothing had happened.
