1. Evidence from adaptations
MIMICRY
CAMOUFLAGE
COEVOLUTION

2. MIMICRY
One organism imitates another; resembles another organism in some way
Do you see a difference in these 2 butterflies?
The butterfly at the top is a MONARCH;
eats milkweed which gives it a bad taste
so birds don’t eat them; The bottom
butterfly is a VICEROY; birds leave
alone b/c it looks like monarch

3. MIMICRY What about these 2 snakes? The top snake is a coral snake,
which is very poisonous.
The bottom snake is a milk-
snake…harmless

4. BENEFITS
Because the harmless organism looks like a poisonous or bad tasting organism…predators leave them alone!
support FOR EVOLUTION
Shows the organism has changed in order to “mimic” another organism or feature

5. CAMOUFLAGE
Organisms have features that allow them to blend in with their environment
Therefore avoid contact with predators (BENEFIT!)
Do you see the organisms in these pictures?
In what way are these organisms camouflaged?
Supports evolution b/c organisms changed to blend in with environment

6. coevolution One organism evolves in response to another
The cabbage plant evolved a toxin to repel insects from eating it
The moth evolved an immunity to the toxin

7. Indo-pacific crabs have been noted to have stronger claws than their cousins in the Caribbean. It is also noticed that marine snail shells are stronger in the Indo-Pacific region than those in the Caribbean.

8. BENEFITS Organism develops a defense against its predators… PROTECTION
Predator develop an immunity to its prey’s defense
Some organisms evolve together in a way that benefits both
