Adaptations-Part 2
Fill the Bill RecapSo what does Fill the Bill have to do with
Adaptations?Lets revisit the birds we discussed….
Why is adapting to the environment important?Adaptation increases FITNESSFITNESS: The current state of an organism
that is adapted to survive and reproduce in its environment
Increased fitness means you are more likely to survive!
Changing EnvironmentIn order to survive, species must continue to
EVOLVE to the changing environmentEVOLUTION is a change over time.
Evolution can occur within a species Evolution can also create a new speciesSpecies can change slightly after each
generation
Beaks that are helpful for eating different types of food
What happens if your food source changes?Sometimes a plant may change slightly….This will change which organism can obtain
food from it easilyOrganisms Co-evolve
Organisms will adapt to the environment together
The change of one species will trigger the change of another
Examples of CoevolutionGarter snake and Rough-skinned newt
Predator/Prey relationshipNewt poisons increase and snake’s resistance
to poison increasesHummingbirds and ornithophilous flowers
Breeding season of hummingbirds and the blooming of flowers is commonly seen around the same time
