What is a simple definition of natural selection?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

What is Natural Selection? Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.

What is Darwin’s theory of natural selection for kids?
He is known for his theory of evolution by natural selection. According to this theory, all living things are struggling to survive. The living things that have the most helpful traits for their environment tend to survive. These living things then pass along their helpful traits to their young.

How does natural selection occur?
Natural selection occurs when individuals with certain genotypes are more likely than individuals with other genotypes to survive and reproduce, and thus to pass on their alleles to the next generation.
What is the purpose of natural selection?
Natural selection enhances the preservation of a group of organisms that are best adjusted to the physical and biological conditions of their environment and may also result in their improvement in some cases.

How do you explain theory of evolution to a child?
Evolution results from a process called natural selection. This process can happen when an individual's genes differ in some way from the genes of others of its kind. Variations, or differences, in genes cause differences in an individual's traits—such as how it looks, its structure, or its behavior.
What is the theory of natural selection?
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
