Charles Darwin

November 24 Charles Darwin controversial Orgin of Species published 1859

The evolution theory states we are what and where we are as the result of "natural selection," the "selecting" done by an animal force that began with o one-cell protozoan, gradually over million of years evolving to the statue of human.

In the year 1831 a crowd gathered around an English port for a glimpse of the large
sea vessel called the H.M.S. Beagle. With the sails wide open, up high a sailor stands in the crow's nest acting like a lookout for things to come. The course is set for South America and the surrounding Pacific Islands. A young man, Carles Robert Darwin, is aboard working as the ship's naturalist. He is observing plant and animal life in their natural environment. The scientific voyage sailed for five years and young Darwin collected data wherever the ship was put ashore. Charles successfully kept exceptional track of all the samples containing all his observations. returning to England he began to evaluate the information he gathered.

While reviewing his research he became very interested in his finding on the Glapagos, an island located in the eastern pacific. On this rather limited geographic area he found it didn't possess a large number of different animal species. Yet a variety of the ones inhabiting the island, 13 different finches and several more tortoise. His studies took over 20 years before his theory of evolution by natural selection was to take form. This theory would make him famous, a show case for the explanation of how we evolved.

A summarization of Charles Darwin's careful examination:

1. No two organisms of whatever kind, whether animal or plant, natural or domesticated, turn out to be exactly alike. The difference in the inborn characteristics of individual organism, termed variations, are to be taken as a law of nature. Every living thing is unique.

2. Plants and animals produce more offspring than can be provided for. There exist
natural checks to compensate for the overproduction of all living forms and to keep
their numbers with in reasonable bounds.

3. The most effective natural check upon overpopulation is the competion of organisms
for space and food-the struggle for existence. Every living thing goes through trails and tribulations to survive.

4. In the course of this constant competition those organisms possessing variations
that make them especially well adapted to the conditions under which they live have a
decided advantage. The struggle for existence results in the survival of the fittest.

5. The better-adapted organisms that manage to survive transmit the traits that
contributed to their survival to their offspring. Your children are a product of you.

6. The inheritance of traits with high survival values furthers the process of natural selection and may in time give rise to a new species.

We are part of the laws of nature.
