What are evidences for evolution?

                What are evidences for evolution?



Evidence that evolution of life forms has indeed taken place on earth has come from many quarters. Fossils are remains of hard parts of life forms found in rocks .rocks form sediments and cross section of Earth's crust indicates the arrangement of sediments one over the other during the long history of earth .

Do you know how the ages of the Fossils are calculated?
Anatomy and morphology shows similarities and differences among organisms of today and those that existed years ago.such similarities can be interpreted to understand whether common ancestors were share or not for example: whales, bats , cheetah and human share similarities in the pattern of bones of forelimbs . Though these forelimbs perform different functions in these animals, they have similar anatomical structure.
The same structure developed along different directions due to adaptations to different needs . This is divergent evolution. Example vertebrate heart or brains .

While another interesting observation supporting evolution by natural selection comes from England. In a collection of moths made in 1850's before industrialization set in it was saw that there were more white winged moths on tree than dark winged however but after industrialization in 1920 there were more dark winged moths in same area .
