327. 人类二号染色体融合时间

from 知为谁 · host 知为谁

这段文字探讨了人类第二号染色体融合的演化事件,该事件将我们祖先的染色体对数从二十四对减少到二十三对。作者讨论了通过分析染色体融合处的端粒 DNA 和非功能性着丝粒等遗传证据来确定这一事件发生的时间。最新的遗传研究估计,这次融合可能发生在四十万至一百五十万年前,很可能是在尼安德特人、丹尼索瓦人和非洲祖先人类的共同祖先中发生的。文章还提到了一项新研究,该研究推测在八十万多年前,人类祖先经历了一次严重的人口瓶颈,这可能与第二号染色体融合的固定有关。最后,作者指出,尽管染色体差异可能导致物种形成,但不同物种间依然可能发生基因渗入,这使得理解这次融合的全部影响变得复杂。内容来源:https://www.johnhawks.net/p/when-did-human-chromosome-2-fuse
