age of the fossil is determined by comparing it to fossils in other layers

• Gene pool

• Relative Dating

• Survival of the fitness

• Geological time scale

record of the life forms and geological events in Earth’s history

• Fitness

• Relative Dating

• Homologous Structure

• Geological Time Scale

Any trait that aids in the chances and reproduction of an organism

• Adaptation

• Endosymbiotic Theory

• Natural selection

• Index Fossil

how well an organism can survive and reproduce in its environment

• Survival of the Fittest

Darwin’s explanation for evolution

Organisms with favorable variations survive and reproduce and pass these on (less desired traits die and aren’t passed on)

• Half Life

• Endosymbiotic Theory

• Gene Pool

• Natural Selection

remnants of organs that no longer function but they did in an earlier ancestor.  Shows evolutionary relationships

• Vestigial Structure

• Half Life

• Homologous Structures

• Analogous Structures

similar structure but different functions, shows common descent and evolutionary relationships

• Homologous Structures

• Half Life

• Analogous Structures

• Vestigial Structure

groups of individuals of the same species that interbreed

They share a gene pool

• Natural selection

• Half Life

• Gene Pool

• Population

all of the genes, including different alleles, that are present in a population
