Answer 1

Explanation:

On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),[3] published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. The book presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had collected on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.[5]

Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. The book presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had collected on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

Summary of Darwin's theory

• Every species is fertile enough that if all offspring survived to reproduce, the population would grow (fact)
• Despite periodic fluctuations, populations remain roughly the same size
• Resources such as food are limited and are relatively stable over time
• A struggle for survival ensues
• Individuals in a population vary significantly from one another
• Much of this variation is heritable
• Individuals less suited to the environment are less likely to survive and less likely to reproduce; individuals more suited to the environment are more likely to survive and more likely to reproduce and leave their heritable traits to future generations, which produces the process of natural selec
• This slowly effected process results in populations changing to adapt to their environments, and ultimately, these variations accumulate over time to form new speciestion
