Evidence from adaptations MIMICRY CAMOUFLAGE COEVOLUTION

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

How does mimicry work for the following pairs of organisms? Milksnake Coral snake

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

What is this adaptation called? CAMOUFLAGE

How is Camouflage an adaptive advantage for living things? Do you see the insect?? He’s hanging upside down!

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

How do these 2 organisms show COEVOLUTION?

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

Caribbean snail Indo-pacific snail Caribbean crab Indo-pacific crab 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. Caribbean snail Indo-pacific snail Caribbean crab Indo-pacific crab

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 Flowers & pollinators
