100
Something that can be inherited through genetic characteristics... means that everyone is different!
What is variation?
100

Malthus, Lamark, Hutton, and Lyell

Who are the scientists that inspired Darwin?

100
Any kind of inherited trait that improves an organism's chances of survival and reproduction in a given environment.
What is an adaptation?
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
Organisms often have more ____________ than will survive.
What is offspring?
200

Darwin observed that farmers could breed cow that had ideal traits to maximize milk and meat production.

What is an example of artificial selection?

200

All of the genes within a population

What is a gene pool?

200
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?"
200
Type of diagram that shows the relationship of organisms to their ancestors as well as common ancestry.
What is a phylogenetic/evolutionary tree?
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

Occurs when females prefer certain traits in males or males fight one another over a female.

What is sexual selection?

300
A group of genetically similar organisms that can mate and produce fertile offspring.
What is a species?
300

the study of the similarities and differences in the embryos of different species.

What is embyrology?

400
The process whereby organisms that have advantages survive and pass their genes onto their offspring.
What is natural selection?
400

Finches beaks or tortoise shells

What organisms inspired Darwin's Theory of Evolution?

400

When a gene pool changes purely by chance, usually significantly affects smaller populations.

What is genetic drift?

400

In natural selection, these are evolutionary forces that favor certain traits of an organism.

What are selective pressures?

400

When organisms diversify rapidly from an ancestral species into a multitude of new species. 

What is adaptive radiation?

500

The three things that need to be happening for natural selection to occur?

What are survival of the fittest, the struggle for existence, and variation/adaptation?

500

The name of Darwin's book published in 1859

What is on the Origin of Species?
500
The random appearance of a new trait in an organism.
What is a mutation?
500

This occurs when phenotypes at both extremes of the phenotypic distribution are selected against. This narrows the range of variation.

What is stabilizing selection?

500

similar structures that evolved independently in two living organisms to serve the same purpose

What is an analogous structure?
