there is this theory called "hybrid vigor"
It states that different races have strengths. If you mix these races together, the offspring will have the strengths of both races.
if blacks are good at running, and the Chinese are good at math, maybe you create offspring that's good at both.
But, this is rare. You will likley just create a kid that can't run or do math.
Race mixing usually creates weaker offspring.
A positive example might be different ethnicities of the same race that mix.
@ToyotaTime The weaker genetic offsrping, regardless of race-mixing or not, would not be an evolutionary problem had we not created an environment that cuddles and protects them at the expense of the more fit.
@Wopu this is how all South American races were created. The Spanish/Portuguese had as much interbreeding as possible and let nature decide which ones would live.
@Wopu @ToyotaTime We should start by Not shaming the so called "Teenage Prenagcy" the most healthy offspring all woman can give to this World is bewteen the age of 16 to 24 years old that is a biogical fact
