Definition of Evolution
"Biological evolution, simply put, is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life."
Charles Darwin and the beginning of Natural Selection
In 1859, Charles Darwin published On the Origin of Species. This was a book detailing his theory of evolution and providing a place for him to show his years of evidence that had taken him across the globe. Darwin had noticed similarities between species of animals, leading to him study and develop his ideas.
βIt is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.β

The Man behind the Theory
Born in 1809, Charles Darwin's father was a medical doctor and his mother died when he was only 8. in 1831, he graduated Christ's college with a bachelor of arts. From 1831 until 1838, he explored and learned on board the HMS Beagle. Dying in 1882, he was buried in Westminster Abbey. In century following his death, DNA evidence was found of his theory. Due to its conflict with creationism, his theory is still the center point of controversy over 100 years later.
