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
• Survival of the Fittest

The 4 mechanisms of evolution are:

• mutation, extinction, adaptation, and natural selection
• variation, environmental changes, extinction, and genetic engineering
• extinction, variation, adaptation, and global warming
• inherited traits, adaptation, genetic engineering, and extinction

Genotype refers to the ...

• physical expression of the genes
• the possible combination of alleles in a gene
• whether an allele is dominant or recessive
• how an organism will appear
