EVOLUTION REV

A species’ entire group of alleles.

• Gene Pool

• Gene Flow

• Genetic Drift

• Population

The introduction of a new individual from one population to another.

• Gene Pool

• Gene Flow

• Population

• Recombination

The process of forming a new species from an existing species.

• Create

• Speciation

• Duplicate

• Stasis

Remains of ancient organisms are called

• Extinctions
• Fossils
• Mutations
• Variations

Darwin theorized that individuals having an advantage due to their traits or abilities will be more likely to survive and reproduce.  This theory is known as

• evolution
• speciation
• adaptation
• natural selection

If an organism has a vestigial structure, that structure likely once had a function in a(n)

• close relative
• early ancestor
• unrelated organism
• embryological stage

the hind leg bones in a whale are examples of

• homologous structures
• analogous structures
• fossils
• vestigals

What is the study of organisms at the early stages of development?

• DNA studies
• embryology 
• extinction
• fossil record

What is this an example of?

• vestigial structures
• embryology
• homologous structures
• fossil record

Structures in organisms that have the same function due to similar environmental pressures.

• Analogous Structure
• Homologous Structure
• Vestigial Structures
