Classification & Evolution

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

• DNA studies
• embryology 
• extinction
• fossil record

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• mutation
• gene flow
• gene pool
• allele

The hind leg bones in a whale are examples of

• homologous structures
• analogous structures
• fossils
• vestigals

Which of the following is a term for a group of similar organisms that can reproduce fertile offspring?

• individual
• population
• species
• fossil

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.

The difference in the physical traits of an individual from those of other individuals in a group is called a(n)

• change
• adaption
• species
• variation
