While humans did not evolve from modern monkeys or apes, we share a common ancestor with great apes from 6-7 million years ago in Africa. The human lineage branched from others that produced great apes, and early humans like Ardipithecus, Australopithecus, and Homo habilis emerged in Africa between 4-2 million years ago. Brain size increased over generations as humans evolved traits like bipedalism and tool usage, allowing our ancestors like Homo erectus to leave Africa around 1.8 million years ago. Modern humans, Homo sapiens, evolved in Africa around 300,000 years ago and spread globally.

- 1. Journey From Monkey to Man Presented by Nehru House
- 2. Did we evolve from monkeys Physical difference Devolution Table of Contents Our timeline Evolution Brain size difference Conclusion Webliography
- 3. Did we evolve from monkeys? Humans are more closely related to modern apes than to monkeys, but we didn't evolve from apes, either.
- 4. They are anatomically similar yet different because of their marked erectness that frees the hands for use as manipulative members. Physical difference
- 5. Human brain allows for - Articulate speech and Abstract reasoning. Difference in Brain Size
- 6. When did humans evolve? Strong evidence supports the branching of the human lineage from the one that produced great apes (orangutans, chimpanzees, bonobos, and gorillas) in Africa sometime between 6 and 7 million years ago
- 7. Ardipithecus ramidus Its the earliest know genus of the zoological family Hominidae. They lived between 5.8 to 4.4 million years ago. Australopithecus These may have been the first primates to get a round mainly by walking upright. Firstly they appeared in east Africa approximately 4.4 million years ago. Homo habilis They are early bipedal hominid species called homo habilies. The unique features about them is they had a larger brain Homo ergaster/erectus This early hominids lived on the ground, walked upright, created tools to aid in hunting. They moved out of Africa approximately 1.8million years ago Homo Heidelbergensis They appeared in Europe, Northwestern Africa and possibly Asia. The species lived from 600000 to 200000 years ago. Homo neanderthalensis They appeared in western Asia and Europe between 200000 and 250000 years ago. They developed to survive the harsh climates in which they lived
- 8. Homo Sapiens The species that you and all other living human beings on this planet belong to is Homo Sapiens Homo Sapiens evolved in Africa 300000 years ago. There was a change in behaviors that helped them respond to the challenges of survival in unstable environments.
- 9. Can we devolve? Technically we cannot, but, never say never because: Globally, there is an increase in mental illness. Our brain size has reduced by 10 per cent. Our IQ is also falling by 7 per cent a generation. Over-stimulation leads to dopamine depletion and brain cell death
- 10. The appearance of man was a climatic event in the history of earth Man evolved from Ramapithecus to Recent man Evolution was of short span of time i.e Pleistocene toHolocene Distribution is according to Natural Resources Man is the finest product in the Evolution Conclusion I hope this presentation has increased your scientific knowledge about ourselves and I hope you have lost a lot of your brain cells
