1. What is an adaptation?

2. Adaptation- A trait that helps an organism survive.
Examples of Adaptations: gills, camouflage, shells, hissing, scent, hibernation, migration
Examples of things are NOT adaptations: athletic ability, learning to hunt, getting lucky

3. Physical Adaptation- A body part that helps an organism survive.
Examples of physical adaptations: body size, claws, shells, gills, camouflage, venom, white fur

5. Behavioral Adaptation:
A behavior that an organism does that helps it survive.
Examples of Behavioral Adaptations: hissing, fighting, mark territory, hibernation, migration, climbing

7. Summary: Condition Physical Adaptations Behavioral Adaptations
Cold weather
Hot weather
Catching Prey
Avoiding Predators
Attracting Mates

8. Summary: Condition Physical Adaptations Behavioral Adaptations
Cold weather
Blubber, thick fur, short limbs, stocky body, white
Migration, hibernation, sleeping underground, sleeping in groups
Hot weather
Long, thin body parts, store water, light colored
Sweating, Nocturnal, migration, stay in shade
Catching Prey
Claws, sharp teeth, fingers, fast, strong, night vision,
Sitting still, hiding, hunting in groups,
Avoiding Predators
Camouflage, size, fast, horns, spikes, venom, wings, webbed
flocking, herding, hiding,
Attracting Mates
bright colors, large size, fancy body parts,
Scents, mating calls, dances,

9. Population A group of organisms that reproduce together.
Wolf population = all the packs in a Habitat OR
All of the packs in an Ecosystem OR
all of the packs in a country OR
all the packs in the World.

11. Species
A population of organism with similar traits that will reproduce in the wild.
Grey wolf – unique species
Coyote – unique species
Red wolf - ? Species or hybrid

13. Variation
Differences in traits between individuals of the same species within a population
What causes variation in living things?
Differences in genes

15. Mutation A change in a gene that creates a new trait in offspring.
Where do mutations happen in a living thing so they can be passed on to offspring?
In the reproductive organs of the parent

17. Fit or Fitness: An organism that survives and reproduces.
Which is most fit?
Super strong rhino or Mouse with 30 offspring.

19. Natural Selection:
Unique traits help an organism survive and it passes those traits to its offspring.
Offspring are born with adaptations.
Not all offspring have exactly the same traits as others because of variation and mutation.
Some adaptations do not help offspring survive long enough to reproduce.
Organisms that do not reproduce do not pass on their adaptations.
The organism’s parents have more organisms with traits that helps them survive.

21. Artificial Selection
People choose traits to pass on in an organisms. Breeding
Wolf  __disposition_  __tame____
 _wild_______
Wild horse  __athletic ability_  ______fast______
 _____slow _____
