Evolution is the process by which organisms have changed over the course of history as a function of the demands of and challenges posed by their environment. The renowned Charles Darwin proposed the idea that change is spurred by the struggle to survive and reproduce, exemplified by behaviors such as attempts to secure food and drink, escape predators, and breed successfully. The more an organism possesses traits that allow it to succeed in such behaviors that ensure survival, the greater the likelihood that its genes will be passed along to the next generation. This process is known as natural selection. Traits that increase the likelihood of survival and reproduction are thus viewed as desirable, and traits that decrease the likelihood of survival are undesirable.
