The process by which modern organisms have descended from ancient ancestors through change over time.

The study of where organisms live now versus where their ancestors lived in the past.

Homologous Structures

Physical features shared by related species inherited from a common ancestor (e.g., limb bones in birds and horses).

Inherited structures that have lost most or all of their original function (e.g., human appendix).

The study of early development; similar patterns in different species suggest a common ancestor.

A set of homologous genes that determine the body plan of an embryo.

Determining if a fossil is older or younger based on its placement in sedimentary rock layers.

Calculating the absolute age of a fossil by measuring the decay of radioactive isotopes.

The time required for half of the radioactive atoms in a sample to decay.

The process where organisms better adapted to their environment survive and produce more offspring.

Selective breeding by humans to promote desirable traits in offspring.

All the genes and different alleles present in a specific population.

The movement of alleles from one place to another.
