Key Terminology (Grade 12 NSC Matric Life Sciences): Flashcards

Hereditary genetic changes in populations across generations

In populations over generations, not in individuals

Organisms that mate to produce fertile, reproductive offspring

Same species individuals in an area; where evolution happens

Environment determines which organisms survive & pass on traits

Humans choose which organisms reproduce based on desired traits

Process where new species develop from existing ones

New species form when physical barriers separate populations

Mechanisms preventing species from producing fertile hybrids

Long stability periods followed by brief rapid evolutionary change
