Natural Selection
This term describes differences in traits within a population.
Variation
Name of the ship Darwin traveled on when studying organisms around the world.
What is the HMS Beagle?
A relationship where both organisms benefit.
What is mutualism?
A type of adaptation where animals blend into their surroundings.
What is camouflage?
True or False: A harmless king snake having the same colors as a venomous coral snake is an example of mimicry.
True
According to natural selection, organisms with helpful traits are more likely to do this.
What is survive and reproduce?
Darwin studied finches and tortoises on these famous islands.
What are the Galápagos Islands?
One organism benefits and the other is not helped or harmed.
What is commensalism?
Camouflage helps prey animals avoid this.
What is being eaten / predators?
True or False: Mimicry can help animals avoid predators by looking dangerous or poisonous.
True
The process where a helpful trait becomes more common in a population over generations.
What is natural selection?
Darwin’s major theory explaining how species change over time.
What is the theory of evolution by natural selection?
One organism benefits, the other is harmed.
What is parasitism?
A chameleon changing color is an example of this.
What is camouflage?
True or False: A butterfly blending in with tree bark is mimicry.
False (That is camouflage, not mimicry.)
This changes which traits give an advantage, causing populations to evolve.
What is a change in the environment?
Darwin observed that finches on different islands had different shaped _____ based on their food source.
What are beaks?
A tick feeding on a dog shows this type of symbiosis.
What is parasitism?
This helps predators get closer to their prey by blending in.
What is camouflage?
True or False: A non-poisonous moth that looks like a wasp is using mimicry to protect itself.
True
A physical or behavioral trait that helps an organism survive in its environment.
What is an adaptation?
Darwin called organisms that are better adapted to their environment more likely to survive and reproduce this.
What is “survival of the fittest”?
A clownfish gaining protection from a sea anemone, while the anemone gets food scraps shows this.
What is mutualism?
Arctic foxes turn white in winter to blend in with this.
What is snow?
True or False: Mimicry is a random behavior that does not help an organism survive.
False (Mimicry increases survival — it’s an adaptation.)
