Charles Darwin and Natural Selection
Charles Darwin
Charles Darwin was born in Shrewsbury, England, on February 12, 1809. In 1831, he travelled on a five-year voyage around the world on the HMS Beagle. He studied ranges of specimens around the world that led him to make his theory of evolution and his views on the process of natural selection. In 1859, he published On the Origin of Species. He died on April 19, 1882, in London.
Charles Darwin was the father of evolution and his theories were well backed up by another scientist who was closing in on the theory as well. His name was Alfred Wallace, an English naturalist and biologist who had nearly the same evidence as Darwin proving the theory could be true. Together they founded the theory of evolution.
Natural Selection:
Natural selection is the process by which traits from all living things become either more or less common in a population as an effective function when reproducing considering the changing environment. The term "natural selection" was made popular by Charles Darwin.
The natural selection process goes as follows, for example a population of beetles.
1. A difference in traits-
There is a population of green beetles and brown beetles
2. Environment-
Due to environment the enemies of beetles, birds eat only the green beetles and survive to reproduce less often than brown beetles do.
3. Dominant trait-
Because of a lack in green beetles due to environment (birds) brown beetles breed more so there is a more dominant trait.
4. End result-
The more advantageous trait brown colouring allows the beetle to have more offspring. If this process continues eventually all the individuals in the population will be brown instead of a mix

Survival of the Fittest:
The survival of the fittest is basically in the name. If you want to survive longer and reproduce more and be healthier you have to be fitter and to be fitter the species must have a better trait from their parents that make them stronger than their parents.
An example is a rabbit
If a rabbit in the snow is a dull grey their is less chance of it surviving as it will be seen to by predators so if they reproduce genes will give the fur of the offspring a lighter shade meaning a greater chance of survival. Obviously this doesn't happen overnight but takes hundreds of years and that is how humans have gotten smarter and adapted more to different climates and environment due to the survival of the fittest.
