The Theory
Charles Darwin
Mechanisms of Evolution
Vocab
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 organsim that has been preserved by natural processes.
What is a fossil?
200
Organisms often have more ____________ than will survive.
What is offspring?
200
Where in England itself did Darwin gain evidence of natural selection?
What is by observing dog breeding!
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
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
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?
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
this type of dating is expensive, sometimes not possible, and destroys part of the fossil in the process
What is absolute dating?
400
A group of genetically similar organisms that can mate and produce fertile offspring.
What is a species?
400
The random appearance of a new trait in an organism.
What is a mutation?
500
What is the idea that some species share a common ancestor?

Common Descent 

500

Who was the other Scientist who worked on Natural Selection?

Alfred Wallace

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

What is the difference between homologous structures, analogous structures and vestigial structures?

Homologous- similar structure different function

Analogous- different structure similar function

Vestigial- no function remanent from an ancestor

500

What are the three patterns of evolution?

Convergent (do not share common ancestor, become more similar)

Divergent (share a common ancestor, become more different)

Coevolution (2 organisms which interact in the environment cause each other to evolve)
