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

Small populations are affected most by chance incidents

What is genetic drift?

100
In natural selection, this is the agent that "selects" for or against traits of an organism.
What is the environment?

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

Also known as migration. Movement of genes from one population to another.

What is gene flow?

200
Organisms often have more ____________ than will survive.
What is offspring?
200

Another name for non-random mating.

What is artificial selection?

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

A type of genetic drift that occurs after a small number of individuals begin to live in a new area.

What is a founder effect?

300
When organisms try to get their fair share of a limited amount of resources.
What is competition?
300

the reason why some organisms have an increase in the chance to survive.

what is genetic variation?
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
An explanation of events in the natural world based on observations. Unlike a scientific law, this can be falsified or changed.
what is a Scientific Theory?
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?

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

what "flows" during gene flow?

what are alleles?
500

specific name to the mechanism of evolution that is happening in Australia right now

what is the bottleneck effect?

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

500

how often an allele occurs in a population
