Wild Card
100

The change in the heritable characteristics of biological populations over successive generations.

What is Evolution?

100
Where was Charles Darwin from?
What is England?
100
In natural selection, this is the agent that "selects" for or against traits of an organism.
What is the environment?
100
the vocab word that means change through time. The theory that existing life forms have evolved from earler forms over long periods of time.
What is evolution?
100
Any trace or remains of a once-living organsim that has been preserved by natural processes.
What is a fossil?
200

The differences in characteristics between individuals in a population.

What is variation?

200

What year did Charles Darwin's expedition begin? 

When is 1831?

200
Any kind of inherited trait that improves an organism's chances of survival and reproduction in a given environment.
What is an adaptation?
200
animals that have certain beneficial traits will survive better over time- survival of the best adapted- nature determines who will "win"
What is natural selection
200

More offspring are produced than can survive, leading to competition for resources.

What is struggle for existence?

300

All species, living and extinct, evolve from ________ _________ and exhibit diversity due to natural selection and adaptation. 

What is Common Ancestors?

300

What was the name of the boat that Darwin sailed in?

What is The Beagle

300
Slang term that descibes how organisms that posess the best traits or adaptations for a particutlar environment are the ones that will successfully pass down their traits to their offspring.
What is "Survival of the Fittest?"
300

How well an organism can survive and reproduce in its environment. 

What is fitness?

300
A group of the same organism that occupies a specific area in a specific time.
What is a population?
400
The process whereby organisms that have advantages survive and pass their genes onto their offspring.
What is natural selection?
400
What animals did Charles Darwin observe that helped lead him to his theory of evolution- and what did he notice about these animals?
What is either finches beaks or tortoise shells
400

Eventually, differences between populations can become so significant that they are considered distinct species.

What is Speciation?

400

Similar structures, like the bones of limbs, that are shared by related species and have been inherited by a common ancestor. 

What are Homologous Structures? 

400
The random appearance of a new trait in an organism.
What is a mutation?
500
Organisms often have more ____________ than will survive.
What is offspring?
500

Where did Charles Darwin's ship land upon return?

Where is Cornwall? 

500
When organisms in separate environments (ex: on different continents) originated from a common ancestor.
What is biogeography?
500

Body structures that are inherited from ancestors but have lost much of their original size and functionality. 

What are Vestigial Structures?

500

The random change of the frequency in which traits are present due to outside factors. Events like natural disasters or movement of the population cause this.

What is Genetic Drift?
