![]() Early apes, such as Proconsul africanus, like the apes of today, lacked tails but still had monkey-like wrists and were unable to swing from branches in the manner of modern apes. The first apes are thought to have appeared around 25 mya in Africa, after having branched off from the old world monkeys. Simians – the group of primates to which all monkeys and apes belong – first appeared at some point between 60 and 40 mya.Ģ5 mya: The Ape Lineage Separates From The Other Simians They were the ancestors of today’s tarsiers, monkeys and apes – including humans. ![]() Early haplorhines were small, arboreal (tree-dwelling) animals that resembled tarsiers. Shortly (geologically speaking) after the Cretaceous–Paleogene extinction event, a group of primates known as Haplorhini appeared. Many mammalian groups – including the early primates – underwent rapid changes as they evolved to fill in the niches left empty by the disappearance of the dinosaurs.

The very first primates are thought to have appeared during the late Cretaceous Period while dinosaurs were still alive.

You can find out more about Primates on this page: Primates: The Ultimate Guideīelow is a list of the major stages in the human evolutionary timeline.Primates is the animal group that contains all of today’s monkeys and apes (including humans), as well as animals such as lemurs and galagoes. The timeline of human evolution below begins with the emergence of the first primates. These characteristics helped them to survive and are present in modern humans today. Their hands became stronger and more dexterous, and they began to walk upright and use tools. This group contained the ancestors of humans together with the ancestors of chimpanzees (our closest living relatives).Īnimals such as Ardipithecus – a chimpanzee-like animal that lived around 5 million years ago (mya) marked the separation of our ancestors from those of today’s chimpanzees and bonobos.Īrdipithecus still lived in trees and had a relatively small brain compared to ours.Īs yet more time passed, our ancestors developed larger brains and flatter faces. The common ancestor of all the great apes is thought to have lived around 20 mya (million years ago), when the great apes branched off from other primates.Īround 7 mya, a group of great apes known as Hominini branched off from the other great apes. In other words, if both you and an orangutan went far enough back into your respective family trees, you’d eventually arrive at the same type of animal! We belong to Hominidae, the great ape family, and share a common ancestor with the other living great apes. Human evolution is the process of gradual genetic change that led, over millions of years, to the development of our species, Homo sapiens. The human and chimpanzee branches only split around 7 million years ago! Human Evolution Chimpazees are our closest living relations in the animal kingdom. Love natural history?
