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
