What is natural selection?
Sharp reduction in population size due to an environmental disaster, often results in loss of variation
When individuals survive and reproduce at a higher rate than others in the same population due to some environmental pressure
Process by which populations have become adapted to their environment over time
Specialized structures and behaviors that aid in survival
What are adaptations?
Sharp reduction in population size due to an environmental disaster, often results in loss of variation
When individuals survive and reproduce at a higher rate than others in the same population
Process by which populations have become adapted to their environment over time
Specialized structures and behaviors that benefit the organism and aid in survival
