Chapter 7 Evolution of Living Things

A characteristic that improves an individual’s ability to survive and reproduce in a particular environment Adaptation

A group of organisms that are closely related and can mate to produce fertile offspring Species

The process in which inherited characteristics within a population change over generations such that new species sometimes arise Evolution

The remains or physical evidence of an organism preserved by geological processes Fossil

A historical sequence of life indicated by fossils found in layers of the Earth’s crust Fossil Record

A genetically determined characteristic Trait

The human practice of breeding animals or plants that have certain desired characteristics Selective Breeding

The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do; a theory to explain the mechanism of evolution Natural Selection

The period between the birth of one generation and the birth of the next generation Generation Time

The formation of new species as a result of evolution Speciation
