Why can yellow and white people have children without reproductive isolation? Do humans really have species?
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 involvedLet's explore together!Firstly, we need to understand what isReproductive isolationReproductive isolationUnable to produce offspring, or the offspring produced are sterileReproductive isolationThe answer isReproductive isolationThe early lifestyle of mixed livingHighly developed cultural mindThe 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 similarThe second reason is thatThe early lifestyle of mixed livingReproductive isolationReproductive isolationThe 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 satisfactionSports abilityThese differences are mainly caused by environmental adaptation, gene drift, gene recombination and natural selectionSkin colorSkin colorDHair and eye colorHair and eye colorSports abilitySports abilityThe appearance differences between humans only account for a small portion of the entire genome (approximately 0.01%)Reproductive isolationThis greatly enhances human genetic diversityIt can realize the flow and integration of cultural genes among peopleReproductive isolationWhich country's girls do you like best?
