New Research: Ocean Acidification May Make Seaweed Species Vulnerable
Xinhua News Agency, Beijing, October 5thWhat is the impact of ocean acidification on seaweed? Swedish researchers recently published a paper in the American journal Current Biology, stating that ocean acidification may affect the chemical balance of seaweed, making its structure and organization fragile and reducing its overall survival chances.Previous research predicted that by the end of this century, the degree of ocean acidification may reach about three times the current level...

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?

100000 years ago, there were at least 6 species of humans on Earth, why were we the only ones left in the end?
The development of human civilization has always been the focus of scientists' research, but in fact, why humans emerged has also been a headache for scientists from ancient to modern times, because regardless of the level of analysis, the birth of humans is too bizarre.To be aware of the vastness of the universe, the emergence of life on Earth alone, and even the evolution of highly intelligent animals like humans, raises doubts about whether our birth was a masterpiece of the Creator...
