Why Skinny Stays in the Picture

A study by evolutionary psychologist William Lassek has concluded, perhaps not surprisingly, that the more muscular a man is, the more sexual partners he has. So why haven’t skinny, fat, or average men been wiped out of the gene pool? One reason, according to Lassek, is that men with bigger muscles have to eat more to sustain themselves and have weaker immune systems. Advantage, skinny! [%comments]
