Humans appeared in southern Africa between 200,000-350,000 years ago. We know we come from Africa because our genetic diversity is highest there, and there are lots of fossils of primitive humansthere. Our closest relatives, chimps and gorillas, are also native to Africa, alongside baboons and monkeys. But primates’ closest living relatives – flyin...
The idea of oceanic dispersalis central to the theory of evolution. Studying the Galapagos Islands, Darwin saw only a few tortoises, iguanas, snakes, and one small mammal, the rice rat. Further out to sea, on islands like Tahiti, were only little lizards. Darwin reasonedthat these patterns were hard to explain in terms of Creationism – in which cas...
Several primate rafting events are well established. Today, Madagascar has a diverse lemur fauna. Lemurs arrived from Africa around 20 million years ago. Since Madagascar has been an island since the time of the dinosaurs, they apparently rafted the 400 kilometre-wide Mozambique Channel. Remarkably, fossils suggestthe strange aye-aye crossed to Mad...
One of Darwin’s great insights was the idea that everyday events – small mutations, predation, competition – could slowly change species, given time. But over millions or billions of years, rare, low-probability, high-impact events – “black swan” events – also happen.

Aug 8, 2024 · human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.

The aquatic ape hypothesis (AAH), also referred to as aquatic ape theory (AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [1]
May 5, 2011 · It may seem strange that humans have evolved from fish, but the evidence can be found not just in fossils but also within our own bodies.
