- Evidence for Human Evolution
- Later, James Burnett, (1714-1799) proposed that humans had evolved from monkeys. or apes
- Most people thought he was mad as he went around searching for humans with tails!
- However,nowfossil evidence suggests he was on the right track.
- Most people thought he was mad as he went around searching for humans with tails!
- The idea that humans were related to monkeys or apes wasn't popular until the 17th century.
- Idea changed due to Carl Linnaeus (1707-1778) published his system of classification.
- His system of classification suggested that humans were related to apes and monkeys.
- Example
- Pavo cristatus is the Indian peafowl
- He also started using a binomial system to name species
- The binomial system uses two latin words and is still used today.

- Fossil evidence
- Scientists use fossils to find out more about human evolution.
- They work out the age of the fossils then put them in age order
- The fossils though, do not show smooth changes over time because some have not been discovered.

- In 1992 scientists discovered some 4.4 million year old fossilised bones from a female of a human like species.
- More of these fossils were found and were given the name Ardipithecus radius.
- The most complete set of these fossils is nicknamed "Ardi"
- Ardi was about 1.2 m tall and 50kg .
- Her leg bones shoe that she could have walked upright.
- She had very long arms though, and very long big toes that stuck out the side of her feet.
- This suggests that she might have been able to climb up trees.

- Lucy was discovered in 1974. She lived 3.2 million years ago and was about 1.07 m tall.
- She could probably walk upright, but although her toe bones were arranged in the same way as modern humans they were much more curved.
- In the 1960s, Mary Leakey (1913-1996) and Louis Leakey (1903-1972) found a more recent human like species.
- This species got the nickname Homo Habilis as they thought it was similar to Humans (Homo sapiens)
- This name translates to 'Handy man'
- These fossils are 2.4-1.4 million years old.
- The animals were quite short with long arms but walked upright.
- This name translates to 'Handy man'
- This species got the nickname Homo Habilis as they thought it was similar to Humans (Homo sapiens)
- Homo erectus was discovered in Asia in the late 19th century and so many scientists thought that modern humans evolved in Asia.
- However, an almost complete 1.6 million year old skeleton was found by Richard Leakey (1944-) in 1984 in Kenya, providing evidence that humans actually evolved in Africa.
- This species was tall (1.9 m tall) and strongly built.

- Stone Tools
- The earliest evidence of human like animals using stone tools dates to about 3.3 million years ago.
- Scientists can work out the ages of different layers of rock. They then assume that as stone tool is about the same age as that layer of rock.
- The oldest stone tools are very simple, but would have helped with skinning and animal or cutting up meat.
- Tools found in more recent rocks are more sophisticated,
