Charles Darwin and Evolution

The theory of evolution, as set forwards by Charles Darwin in 1859, stated that all plant and creature life evolved everywhere long periods of time from simple to more complicated forms through mutation and adaption. He also taught that only if the fittest on each species would endure. This concept is called Evolution by ingrained Selection. Natural endurance is that the strongest survive and propagate and then increase in the strength of the species.

On the Galapagos Islands, the versatile species established themselves and determined territories. Evolution then set in and many unique species, such as Darwins finches, resulted. These finches probably descended from genius type of ancestor and then, due to isolation and through chance, divergent climates and natural forces such as aliment availability and type, they evolved into bakers dozen different types of finches. So in short, based on the food availability and types, certain fiches survived. The process of their evolution would probably dedicate began with immigrates from the mainland. As they dispersed to different islands, new populations would be formed. each time these satellite populations dispersed, in that respect would be greater differences among the individual species.

Natural selection works as follows:

1. Variations exist in any population.

2. In and generation there argon individuals that do not reach maturity and reproduce. Their characteristics argon removed (passed on)

3.



The organisms that survive to reproduce are best adapted to that environment as they have the variations that allowed them to survive (Survival of the fittest)

4. These favourable variations are passed onto the next generation, which pass away more and more common.

Some evidences of evolution include:

The Age of the Earth

Evolution can only take place over enormous periods of time. The fact the Earth has been dated 4,500 million long time old which allows evolution to be possible.
