The process by which species cease to exist is
What is extinction?
100

What is a Loooooooooooooooooooooooooooooooooooooong time?
100
What is the vocabulary for "survival of the fittest"?
What is Natural Selection?
100
Darwin observed that the shape of these finches _________ were well matched with the seeds available in their own distinct environment.
Beaks
100
A characteristic that an organism can pass on to its offspring through its genes.
Trait
200
The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
Natural Selection
200
What would happen if the environment changes drastically and no organisms have fitting adaptations?
What is a species could go extinct?
200
Yellow beetle and green beetles live in the rainforest canopy. You would expect:
What is the green population will increase and the yellow will decrease?
200
Can an organism "CHOOSE" to evolve and change?
No, organisms CANNOT CHOOSE to change their genes or traits!
200
Why is variation important to natural selection?
Without variation, all organisms would respond the same to environmental changes
300
What is a change in a gene that results in a new trait?
What is a mutation?
300
What is another name for artificial selection?
selective breeding
300
Polar bears developing thick fur to survive cold climates is what type of selection?
natural selection
300
What is most likely to happen to moth populations in the picture shown?
Dark moths--hunted easily, dark moths--population decreases.
300
The process through which species change over time
Evolution
400
What is it called when an organism has to survive and reproduce in its environment
What is Adaptation?
400
Evidence of the changes in a species' physical characteristics over long geological periods can best be shown through a study of
What is the fossil record
400
After traveling to the Galapagos Islands, Darwin noticed a lot of variation among beak sizes in Finches. This variation was a result of:
Developing different adaptations in order to survive on particular islands
400
What evidence supports that natural selection has occurred in nature?
fossils, fossil record
400
The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?
Dark moth
500
The occurrence of different traits between different individuals of a population
Variation
500
What happens if all organisms in a species have the same traits?
They can’t adapt well to change and might die out.
500
Explain the difference between artificial and natural selection.
Artificial selection is done by humans and focuses on the traits that we find to be the most valuable to us. Natural selection is done by nature and is focused on the traits that would survive best in the environment.
500
What is one advantage and one disadvantage of artificial selection?
Advantage: Produces desired traits. Disadvantage: Reduces genetic diversity.
500
Who authored the book On the Origin of Species by Means of Natural Selection?
What is Charles Darwin?
