Today, I want to talk to you about a very interesting topic:Why can the white, black and yellow people on the earth combine with each other and have children without reproductive isolation?

This question seems simple,The mysteries of human origin and evolution are actually involved

Let's explore together!

Firstly, we need to understand what isReproductive isolationReproductive isolationUnable to produce offspring, or the offspring produced are sterile

Reproductive isolation

The answer is

Reproductive isolation

The early lifestyle of mixed livingHighly developed cultural mind

The first reason is the kinship and stable fertility traits of human originOnly about 200000 years agoHumans on EarthEthnic differences mainly stem from variations in representational expression, such as skin color, body shape, etcAnd the reproductive system remains highly similar

The second reason is thatThe early lifestyle of mixed livingReproductive isolationReproductive isolation

The third reason isHighly developed cultural mindDeeply influenced by the environment and social cultureHumans can also bridge these differences through psychological and cultural cognitionCross racial or cultural heterosexual relationships to gain unique attraction and satisfaction

Sports abilityThese differences are mainly caused by environmental adaptation, gene drift, gene recombination and natural selection

Skin colorSkin colorD
Hair and eye colorHair and eye color

The appearance differences between humans only account for a small portion of the entire genome (approximately 0.01%)

Reproductive isolation

This greatly enhances human genetic diversity

It can realize the flow and integration of cultural genes among people

Reproductive isolation
