In Which I Discuss Evolutionary Roots

      From class, I have been able to learn that Darwin was not the first to propose the evolution theory and that it does not state that we came from monkeys! There is even the words 'survival of the fittest' to be addressed. Evolution usually takes place on a smaller scale, this concept is called Microevolution.  So let's get started.

     Darwin was actually picking up on his own grandfather's and several other scientist writings and was profoundly influenced by the bible work. After a long journey on the seas, he was able to study island finches and little differences that helped them survive in their part of the island. Though they were all the same bird, some had longer beaks that lived in rocky areas so they could reach food. Some showed different patterning and color to help defend them against predators based on their area of the island. This shows the vast capabilities of the body to adapt and change from one central point.


     Microevolution takes place nearly everyday and shows us that little things can effect entire populations of species and food chains. Its definition is ' evolution on a small scale specific to only one species.'  The important parts to microevolution are Mutation, Migration, Genetic Drift, and Natural Selection. Mutations are when two parents look the same, but create a child that is wildly different. This is achieved through a series of recessive genes. Migration deals with populations within a species relocating (probably to a better area that they are adapted to) leaving the original species with a majority of one type. Genetic Drift is when by pure chance of those recessive genes, an influx of the mutation becomes prominent within the population. Finally, Natural selection is the ablility to survive longer based on ones genes. A tan mouse will be safer in the sand than a black mouse, yet a black mouse will be safer on lava rock than a tan mouse.

This picture actually does break it down nicely. A lot of Darwins' prime examples stem from beetle colors and population.
