Evidence of Evolution

The similarities of the bones in the diagram provide evidence that -

• The organisms shown may have developed from a common ancestor

• The organisms shown lived in the same natural environment

• The organisms shown have the same genetic diseases

• All vertebrate species have identical forelimbs

Adaptations are:

• physical or behavioral characteristics that do not help the organism in any way.

• physical or behavioral tendencies.

Which type of fossil dating is the most accurate?

• Radiometric / absolute dating with Carbon-14

• Relative and radiometric dating are equally accurate

• Relative dating

• Neither relative and radiometric dating are totally accurate in determining the age of a fossil

Evolution is best defined as:

• the process in which nonliving things fossilize

• the process in which organisms die

• the process in which organisms change over time

• the process in which organisms that are extinct become revived
