• close relative

• early ancestor

• unrelated organism

• embryological stage

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures

• analogous structures

• homologous structures

• fossil structures

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• Hardey-Weinberg equilibrium within a population

Why is the fossil record incomplete?
