Introduction

´╗┐Describe the development of scientific theory, highlighting the processes involved. Charles Darwin evolution theory. This theory was first to come forth by Jean Baptiste de Lamarck who was the first French scientist, but Charles Darwin was the one who had significantly backed up evidence whereas Jean Baptiste just had an alternative theory. One of the two theory?s Jean Baptiste came up with was; an animal becomes bigger and stronger, and any feature of an animal that is improved through use is passed to its offspring. 'On The Origin of Species' was published in 1859. On The Origin of Species was a scientific literature which was discovered twenty years after his epic journey on the HMS Beagle. ...read more.

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. ...read more.

Conclusion

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! http://www.evolutionnews.org/horseevolution.png After five years Darwin came back to England in October 1836, and sent his specimens to experts to study.

    The more genes to living things share, the more closely related they are. This helps scientist to work out where species fit into the evolutionary tree.?
