A trait of a living thing that helps it survive in its environment.
100
Identify which of the five points of natural selection this represents:
fish lay hundreds of eggs
Overproduction
100
What is one type of evidence for evolution?
Fossils, body parts that have no purpose, similar skeletal features, DNA
100
Where did the study of the peppered moths take place?
England
100
Who suggested the theory of evolution?
Charles Darwin
200
What is an example of a structural adaptation?
Any body part that allows a living thing to survive in its environment. (examples: giraffe's long neck, human thumbs, teeth, gills, wings, specialized beaks, long tails...)
200
Identify the point of natural selection:
The only type of worm there is now is the type that eat at night.
A population will change over time - evolution
200
What is one example of a body part that no longer has a purpose?
human appendix, whale pelvic bones
200
What were the genetic variations of the peppered moth?
Speckled (light) and black (dark)
200
Where in the world did Darwin get his ideas for evolution?
The Galapagos Islands
300
What is an example of a behavioral adaptation?
Any action that allows a living organism to survive in its environment. (examples: moths flying at night, camouflage, bears that hibernate during the winter, male penguins that watch the babies....)
300
Identify the point of natural selection:
there are bunnies that eat only grass and there are bunnies that eat berries and flowers.
Genetic variation
300
What is an example of similar skeletal structures?
forearm of human, bat, cat, alligator, whale, penguin
300
How did the environment in England change?
The coal burned in the factories turned the trees black.
300
Why do species change over time?
Their environment changes and the fittest adaptations survive and reproduce.
400
If you cut off the claws of a male and female cat, will their kittens have claws?
Yes!
400
Identify the point of natural selection:
arctic foxes with white coats are less likely to be eaten by predators than their grey-coated litter mates.
Survival of the fittest.
400
The more DNA that two living things have in common, the more or less (pick one) related they are.
They are more related.
400
What happened to the populations of light and dark moths over time?
The light moths decreased and the dark moths increased.
400
Why is variation important to te survival of a species?
Natural selection selects the trait that is best suited for the environment.
500
From the question for $400. Why will the kitten have claws even though their parents don't"
The lack of claws is not a genetic trait. They were removed by a person. The kittens will inherit the normal gene for claws.

Briefly describe your natural selection story to your partner - page by page.
Answers may vary. :-)
500
What do we call body parts that no longer have a function?
Vestigial body parts
500
How do moths behave in terms of motion in order to adapt to their environment and avoid being eaten by birds.
Behavioral adaptation - they only fly/move at night when the birds are sleeping.
500
Why is overproduction and competition helpful to the species as a whole?
Those that are least fit to the environment don't survive, so only the fittest survive and reproduce, which makes a species stronger.
