5. Natural Selection in Five Steps
name & description of step
sketch example
DETAILS TO INCLUDE
natural populations growing faster (many offspring) than their limited food supply or other resources
genetic variation causes some individuals to have more favorable traits (adaptations) and some individuals to have less favorable traits in that environment (camouflage, helpful structure/behavior)
most individuals with less favorable traits die, while most individuals with more favorable traits survive
survivors with more favorable traits reproduce, passing on this trait, few
offspring with this trait are better at the Struggle to Survive in the next generation compared to few offspring with less favorable trait
