Detailed explanation-1: -Charles Darwin is commonly cited as the person who “discovered” evolution. But, the historical record shows that roughly seventy different individuals published work on the topic of evolution between 1748 and 1859, the year that Darwin published On the Origin of Species.

Detailed explanation-2: -Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.

Detailed explanation-3: -Charles Darwin’s theory of evolution by natural selection is the foundation upon which modern evolutionary theory is built. The theory was outlined in Darwin’s seminal work On the Origin of Species, published in 1859.

Detailed explanation-4: -There are four principles at work in evolution-variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
