Analogy & Homology

Bats and humans have homologous traits.  Bats and humans are vertebrates and both have skeletons and its traits are passed generation to generation.  Humans front limb bones are homologous to the bones of a bats front limbs; both of their front limbs in five and the parts are different sizes and they look similar.

            

Analogy is something comparable and similar but no relation to each other.  For example, animals with wings like birds, insects, bats, etc. are considered to be analogy.  Insects and birds have wings.  Insects have boneless wings and birds have bones.  Some insects have scale wings and birds usually have feathers on it.  They are different species but share a trait and that is wings and they fly with them, so therefore there environment is the same.  The trait wings itself is an analogy.

Historical Influences on Darwin

Charles Darwin was an evolution scientist who is famous for his theory. His influences were from people like Linnaeus and his classification system. Also Lamarck, he was known for his Theory of Inheritance of Acquired Characteristic, Lamarck ideas were similar to Darwin and was the first to come out with this theory. Lamarck believed was more complex that organisms are not altered by their environment, and that a change in the environment causes changes in the needs of organisms living in that environment, which in turn causes changes in their behavior. The altered behavior leads to greater use of a given structure or organ and use would cause the structure to increase in size over several generations, where the disuse would cause it to disappear. Also the result of these laws was the continuous, gradual change of all organisms, as they became adapted to their environments; the physiological needs of organisms, created by their interactions with the environment. This was Lamarck evolution theory. Now this is Similar to Darwin’s because it had the same concept which is adaptive change in ancestry, ultimately driven by environmental change, over long periods of time.

Desert Island

If I was stranded on a deserted island and I can only take two items with me one of the items would definitely be a cell phone because I can hopefully get signal and call or text also you can play games and etc.  The second one would be a boat so I can leave the island.
