“Much of the concern about very young girls getting pregnant has to do with the girls physical readiness to carry and bear a child.”
If you believe in evolution, then it is irrelevant how old the female is as long as she is post pubescent. Females have egg cells and can be impregnated even before she reaches her teens. That’s just nature. And males develop sperm around the tween – to 13 age bracket. You see, nature is not an entity and therefore it could never have imagined that we would go from grunting and growling and throwing spears at our potential dinner to being the modern version of mankind that we have become.
Now then, if you believe in a god and the scriptures in the bible, the same irrelevance applies because according to die-hard bible scholars, “Mary” was between 13-15 yrs of age when she was impregnated with “Jesus”. If you’re going to say that a teenager’s age is what caused the unhealthy birth and eventual death of a baby, then you need to debunk the bible (if you are a believer).
