In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization, from kingdoms to species, and individual organisms and molecules, such as DNA and proteins.

Our species, Homo sapiens, has now spread to all parts of the world but it's generally believed that we originated in Africa by about 200,000 years ago. We interacted with local archaic human populations as we colonised the globe.
During the 1980s and 1990s the fossil record, while growing, was not able to clearly demonstrate whether Homo sapiensevolved from local ancestors across the globe or originated in a single region and then dispersed. DNA studies generally supported the single origin theory, but were still in their infancy. The two major and opposing opinions were kn...
Latest findings – including new fossils and improved DNA research and dating techniques – confirm the complexity of modern human (Homo sapiens) origins. Evidence still suggests that all modern humans are descended from an African population of Homo sapiensthat spread out of Africa about 60,000 years ago but also shows that they interbred quite exte...
Charles Darwin's theory of evolution by natural selection made us rethink our place in the world. The idea that humans shared a common ancestor with apes was a challenge to the foundations of ...
The final part of the gallery explores how our species, Homo sapiens, originated in Africa, before dispersing around the world and becoming the only surviving species of human left today. Modern humans evolved in Africa around 200,000 years ago.

Oct 25, 2024 · Almost 100 species are known from some 30 locations worldwide, primarily sandstone formations. Most Ediacarans, presumed to have languished in sandy seaside locales, probably depended on their internal microbial symbionts (photo- or chemoautotrophs ) for nourishment .
