- 遗传学
- 考古学
背景情况:
- 传统的"出非洲"模式表明,大约6万年前,现代人类 (智人) 单次分散,取代了所有土著人口.
- 这种模式越来越受到亚洲新证据的挑战.
研究的目的:
- 修改早期人类在亚洲的传播方式.
- 结合多个科学领域的最新发现.
主要方法:
- 考古证据的分析.
- 人类古生物学发现.
- 地质年代学和古环境学研究.
- 现代和古代人口的遗传分析.
主要成果:
- 越来越多的证据表明人类在6万年前向亚洲散布.
- 早期的人类群体遇到和交配古老的原始人,如尼安德特人,丹尼索瓦人,以及可能的Homo floresiensis.
- 现代人口中的遗传痕迹表明土著群体的取代不完全.
结论:
- 这种"出非洲"模式需要大幅修改.
- 人类在亚洲的早期分散是复杂的,涉及多个波浪和杂交.
- 后来的人口替代并不是绝对的,留下遗传.

Synteny and Evolution
3.8K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

What is Evolutionary History?
43.8K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Evolutionary Psychology
1.1K
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Eukaryotic Evolution
42.5K
The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.
Contrary to the endosymbiont theory, the eukaryote-first hypothesis proposes that the simpler prokaryotic and...
