Differential reproduction
Organisms that are constantly exposed to dangers, which can kill them in mass, have evolved to reproduce in high numbers so that enough of a species will survive and continue the species. Survival of the fittest and natural selection is a common practice among organisms that reproduce fast and in high numbers.
Evolution is the change in allelic constitution of a population gene pool over time. As organisms reproduce, some variants reproduce less, others more, causing some alleles to increase their frequency in the gene pool, while other allele frequencies decline. It is the differential reproductive success of variants in the population that drives this change.
A group of organisms that can mate and produce offspring which can themselves mate is called a species.

Differential reproduction
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring

The main way individuals are added to the population (with animals) is the birth of new offspring.

Overproduction of offspring and more changes like adaptation for survival.
