JW: There is no real _heat_ season for any specie of mammal
equatorial conditions. So what made the hominids special?

JW: Sexual cues tend to vary according to the habitat and
system. In this context, ape species with polygamic mating
are virtually devoid of visual cues. The dimorphism of
fossils implies that they had a polygamic mating system.
does that square with the Darwin-Mennen theory, Barry?

JW: Does it really take a few million years to solve
equations? No wonder I failed at maths.
