Answer:
This is the basic idea behind his theory of Natural selection
Explanation:
The theory of Natural selection was demonstrate in Darwin's book known as 'Origin of species' which was written in 1859
In this book, the process of change of an organism over time is described and also mentioned about their physical as well as behavioral changes.
Natural selection means the survival and reproduction of individuals by changing the phenotypes.
Natural selection is a process by which the nature accepts those organisms that can change their phenotype in order to survive with changing environment and eliminate those phenotypes that are not favorable for their survival.
One example of a mutation that could occur in a species that might increase its lifespan is increased bone density. With high bone density, an animal is more likely to survive a heavy hit with no bone damage. This, in turn, means that the animal's vital organs are able to be protected by the bones, meaning the difference between life and death.
