It happens throughout the animal kingdom. The new male kills the offspring of the previous male, thus bringing the female into estrus more quickly. [This comment is best read in a David Attenborough voice.]
I think this situation aligns to the animal kingdom differently.
More like why the fox wants to sneak into the hen house. The prey he is after is an easy target once he’s breached the fence!!
Yeah, pretty sure a human males interest in a 13 year old isn’t about her mother’s estrus.
Humans are not lions or any other species of animal whose males kill the offspring of other males to obtain that male’s female)s) and territory-and animals kill for survival-it is instinct for them-animals are not evil. Humans have the capacity for evil-like a man who is a sex offender/is attracted to girls younger than the age of consent. That is not instinct-that is flat out criminal and f’ing crazy-someone who belongs in a prison for life, or should be put in front of a firing squad if they murder someone...
