Evolution Vocabulary Quiz

Structures that have no apparent function and appear to be residual parts from a past ancestor

• Gene Flow

• Homologous Structure

• Vestigial Structure

• Hardy- Weinberg Equilibrium 

This type of evolution often occurs when closely related species diversify to new habitats.

• Vestigial Structure

• Divergent Evolution

• Parallel evolution

• Genetic drift

Process by which organisms that are most suited to their environment survive and reproduce most successfully; also called survival of the fittest

• Homologous Structure

• Natural Selection

• Hardy- Weinberg Equilibrium 

• Non-Random Mating

Random change in allele frequency caused by a series of chance occurrences that cause an allele to become more or less common in a population

• Parallel evolution 

• Mutation Evolution

• Natural Selection

• Genetic drift

The movement of genes into or out of a population

• Gene Flow

• Natural Selection

• Hardy- Weinberg Equilibrium 

• Convergent Evolution

Process by which unrelated organisms independently evolve similarities when adapting to similar environments

• Non-Random Mating

• Hardy- Weinberg Equilibrium 

• Gene Flow

• Convergent Evolution

Occurs when two species evolve independently of each other, maintaining the same level of similarity.

• Parallel evolution 

• Mutation Evolution

• Convergent Evolution

• Divergent Evolution

Principle that states that allele frequencies in a population remain constant unless one or more factors cause those frequencies to change

• Convergent Evolution

• Hardy- Weinberg Equilibrium

• Homologous Structure

• Divergent Evolution

Organisms may prefer to mate with others of the same genotype or of different genotypes

• Mutation Evolution

• Natural Selection

• Non-Random Mating

• Divergent Evolution

A mutation is a change in DNA, the hereditary material of life. 

• Parallel evolution 

• Gene Flow

• Mutation Evolution

• Genetic drift
