11 Quotes by Ralph Catalano

We can never use humans to directly test out the theories. We can only make inferences based on natural observation.

One argument is that it was conserved to help us lift buses off of pedestrians who just got hit. My belief is that nature conserved the stress mechanism because of its effect on gestation. Natural selection doesn't care about individuals, it just wants poundage and conservation of genes. It found a way to maximize the pounds and the genes.

Statistically, it is clearly true; compared to men, (women) are biological fortresses.

The argument is that in most species, males will compete with each other for females, and females prefer robust males.

You get rid of the weak, and on average the cohort lives longer.

The weak boys got culled out and those boys that survived are hardier on average. They live longer.

It's not in her evolutionary interest to have a weak son in times of stress. He may not survive or may not be competitive for females.

Because male fetuses are more fragile than female fetuses, they are more likely to be damaged.

These findings demonstrate yet again that we need not go to museums of natural history to find evidence of natural selection.
