Describe the development of the theory of evolution, highlighting the processes involved.

After five years Darwin came back to England in October 1836 by Charles Darwin and sent his specimens to experts to study. Darwin collected 13 similar BUT different species or finches. Each of the finch species had a unique bill specialised for particular food source.

Fossils are very hard to find, usually seen on TV or a museum, you would be really lucky to find one. Fossils are remains or traces of animals or plants that lived in the past. There are two types of fossils, body and trace. Body obviously is the remaining parts and trace is more or less evidence for example, foot prints or trails. Fossils are similar to the clues police use to solve a crime. Each fossil tells a story and is vital. For example the police don't have to find a print of every footstep taken by the criminal or confirm everything that he/she did, but the clues paint a logical outline

When Darwin got to the end of his theory of evolution one of the greatest weaknesses was that he was missing an explanation for the inheritance of traits. DNA was the crucial piece to make the theory of evolution whole. However Francis Crick and James Watson discovered the structure of the DNA which was a missing factor, after Crick and Watson discovered this it helped scientist to work out how it functioned. The chimpanzee and the bonobo are human’s closest living relatives. Human, chimps and bonobo descended from the same ancestor specie that lived over 6million years ago. After years of researching they discovered chimps have 99.8% of their DNA similar to humans!
