Wild Card
100
Something that can be inherited through genetic characteristics... means that everyone is different!
What is variation?
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 organism that has been preserved by natural processes.
What is a fossil?
200
What was Lamark`s Theory of Evolution? 

Lamarck proposed that changes in an environment caused an organism’s behavior to change, leading to use or disuse of a structure or organ.

What are Dawrin`s Theory 4 principles of Natural Selection. 

Variation

Overproduction

Adaptation

Descent with modification

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

What type of reproductive isolation is this?


Squirrel population split by Colorado River 10,000 years ago.


What is Geographic isolation. 
300
When organisms try to get their fair share of a limited amount of resources.
What is competition?
300
What was the name of the boat that Darwin sailed in?
What is The Beagle
300
Slang term that describes how organisms that posses the best traits or adaptations for a particular environment are the ones that will successfully pass down their traits to their offspring.
What is "Survival of the Fittest?"
300

What type of Genetic Drift is this?


The serve over hunting of northern elephant seals for their blubber to be use in lamp oil greatly depleted the species’ numbers and genetic variation.

Bottleneck Effect.

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
What is genetic drift? 

Genetic drift is a way by which allele frequencies can change due to chance.


400
A group of genetically similar organisms that can mate and produce fertile offspring.
What is a species?
400

What type of reproductive isolation is this?


Meadowlarks singing different songs to attract mates; courtship (dating)


What is Behavioral.
500

What was one theory of how the dinosaurs died off. Also what is it called when a catastrophic event such as an ice age or asteroid impact happens and wipes out a large amount of the population.


Mass Extinction


500
What is artificial selection?
Selecting to breed organisms for desired traits.  
500
When organisms in separate environments (ex: on different continents) originated from a common ancestor.
What is Bio Geography?
500

What type of effect is this?


The Amish community is genetically isolated because few outsiders join the population and Amish usually do not reproduce outside of the community therefore polydactyly is much more frequent in Amish communities than in others.


The Founder Effect.

What is a gene pool?

A gene pool is the combined alleles of all the members in a population.
