Evolution Vocab. Terms SB 5

Evolution Change over time

Natural Selection Survival of the Fittest – a mechanism (“how”) of evolution 4 Parts

Innate Behavior Behavior you’re born with – genetically based behaviors

Adaptations Inherited traits developing over time in response to the environment that allows an organism to survive. EX: Camo & mimicry

Genetic Equilibrium Alleles are not changing, so evolution is not occurring

Learned Behavior Behavior that is taught

Predator Hunt for prey

Diversity Variations / Differences

Mutation Permanent change in DNA – adds new alleles to the population

Fitness Being “fit” in the environment means organisms are most likely to survive & pass on their genes.

Theory Based on observations and research – not proven!

Vestigial Structures Structures that have no noticeable purpose to modern day life
