Evolution is different kinds of living organisms . They are thought to have developed and diversified from earlier forms during the history of life on earth . Evolution is also the development of something from a simple complex form . It is change in the heritable traits of biological populations over successive generations . For example the closest thing to a human is a chimpanzee .

Fossil Record is one examples of evolution it is life's evolutionary epic that unfolded over four billion years ago . It has environmental conditions and genetic potential interacted in accordance . Fossil record plays a part in natural selection as well animals are things that are made to live on this earth and die quickly hoping one of their children make it . In the fossil record you will see some animals that did not live very long to keep reproducing and you will see the ones that have lived long enough to reproduce and develop .

Embryology is another example of evolution it studies the development of gametes which are sex cells . It also is fertilization and development of embryos and fetuses …show more content…
Homologous structure are structures that are similar to other species . For example a bat and a human have all the same parts in their arm but a bat uses its arms and hands to fly while we use are to lift and touch . Analogous structures are structures that pertain to the various structures in different species having the same appearances . Examples are a bat and a butterfly they both use their wings to fly but a butterfly has no bones and a bat does . Vestigial structures are structures that seemingly have no purpose or function . In your body you have a appendix that you do not need and you do not yous it is just their . A whale has a bone for a leg that was once their but is not their any more so their for it's just floating or sitting their doing nothing
