Darwin referred to this as survival of the fittest. Over time, it results in changes in the inherited characteristics of a population because organisms with adaptations that make them fit for their environment will survive and reproduce better than those without favorable traits.

• Natural Selection

• Genetic Variation

• Homologous Structures

• Struggle for Existence

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.
