Human evolution timeline chart, with details on each of the major stages of human evolution.
On this page you’ll discover how modern humans evolved from the very first primates – animals that shared Earth with the dinosaurs over 80 million years ago.

The exact time humans first appeared is difficult to judge because species don’t come into being overnight. Rather, they change and evolve slowly from ancestral species.
Because the first human remains date back to around 315,000 years ago, our species will therefore have appeared some time before this. DNA evidence from human chromosomes indicates that humans (scientific name: Homo sapiens) may have first appeared more than half a million years ago.
Biology is the study of biota – living things. This includes humans, animals, plants, bacteria and viruses, together with their constituent parts (cells, organs, etc.). Biology also includes the study of the non-living components of living things, such as DNA, proteins and carbohydrates.
Like all science, biology is driven by curiosity. Biologists explore questions like:
