尼安德特人(Homo neanderthalensis),简称尼人,也被译为尼安德塔人,常作为人类进化史中间阶段的代表性居群的通称。 因其化石发现于德国尼安德特山谷而得名。 尼安德特人是现代欧洲人祖先的近亲,从12万年前开始,他们统治着整个欧洲、亚洲西部以及非洲北部,但在两万四千年前,这些古人类却消失了 他们不是今天的智人, 这群人智力低下, 最后被智人消灭。这可以解释今天的印度人的智商 A 2024 study of nearly 2,700 people in India found that modern Indians have a large amount of Neanderthal DNA in their genomes, more than any other group in the world: Neanderthal genomeThe study found around 50% of the Neanderthal genome in Indians, which is about 90% of all known Neanderthal genes that have entered human populations. This is more than double the amount found in a similar study of Icelanders. The study also found that nearly 12% of the Neanderthal sequences in India are unique and have not been found in other regions. Denisovan genomeThe study also found around 20% of the Denisovan genome in Indians, which are close relatives of Neanderthals and modern humans. Indians also have the greatest variation in Denisovan genes among Eurasian populations.

The study also found that most of the genetic variation in Indians comes from a single major migration out of Africa that occurred around 50,000 years ago. The researchers collected genomes from people in 23 states, including Delhi, Maharashtra, Punjab, Rajasthan, and Haryana. Generative AI is experimental. Featured snippet from the webNotably, 90 per cent of Neanderthal sequences found across the world are seen in India. Indians also harbour the largest variation (positioning of genes in the genome) in Denisovan genes among Eurasian populations. This makes Indians quite unique and complex. |
