Unit 9 Evolution

Hereditary changes in groups of living organisms over time

• natural selection

• adaptation

• evolution

• variation

Theory of evolution developed by Darwin, based on four ideas.

• evolution

• natural selection

• fitness

• adaptation

Darwin's term for the selective breeding of organisms selected for certain traits in order to produce offspring having those traits.

• embryology

• natural selection

• variation

• artificial selection

Inherited characteristic of a species that develops over time in response to an environmental factor, enabling that species to survive.

• fitness

• natural selection

• adaptation

• evolution

Measure of a traits relative contribution to the following generation.

• fitness

• adaptation

• homologous sturctures

• variation

Group of organisms that can be interbreed and produce fertile offspring.

• evolution

• species

• enbryology

• DNA fingerprint

Preserved evidence of an organism that provides evidence of past life.

• species

• analogous structures

• homologous structures

• fossil

The study of the formation, development, structure and functional activities of embryos.

• DNA fingerprint

• Evolution

• Embryology

• Adaptation

Anatomically similar structure inherited from a common ancestor.

• vestigial structures

• homologous structures

• analogous structures

• embryology

Reduced form of a functional structure that indicates shared ancestry

• vestigial structures

• homologous structures

• fitness

• analogous structures
