55 million years ago, a dog sized animal had formed, this would be the ancestor of the first horse. 37-32 million years ago, messohippis formed. Then 24-11 million years ago, parahippus and merychippus had formed.Then aproximately 12-6 million years ago, th grandfather of horses formed, the pliohippus. This led to th Dinohippus 13-5 million years ago. This created the Equus -a horse- which started 5 million years ago.
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows the change in the shape of skulls. For example, skulls used to have a sloped front and a smaller head. Now humans have a larger head and more features. Another explanation is the tools. They started out big and clunky, but now are small and refined.
This video produces a timeline about evolution. Which includes the evolution of: Fish, Amphibians, Reptiles, Dinosaurs, Mammals, Primates, Apes and Humans. This timeline gives the aproximation in years of how evolution happened.
This video gives a visual of how evolution occured step by step. Evolution started of with on celled organisms which slowly transformed into animals such as fish, reptiles, and mamals. This visual helps show the transformation starting from one celled organisms to -the present- humans.
