Charles Darwin had the opportunity to board the HMS Beagle at the age of 22 in 1831
During his 5 year journey, Darwin filled many notebooks with information and facts about various animals and plants that he picked up on his travel.
He found more than 1500 different species in the process
Darwin proposed for ‘Natural Selection’. Since resources are limited in nature, organisms with heritable traits that favourite survival and reproduction will tend to have more off spring than their peers, causing traits to increase in frequency over generations.
Natural selection causes populations to become adapted to their environment over time. It also depends on the environment and requires existing heritable variation in a group
Darwin published a book called “on the origin of species”. He presented a theory of evolution based on natural selection. He started his research in the 1830’s. He waited for 23 years to present his research because he knew that his findings would result in religious and scientific debate.
