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

A scientist who would study the history of life through the examination of fossilized organisms.

What is a paleontologist?

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

When one event or action (the cause) directly leads to a certain result (the effect). (Example: a drought causes a shortage of food).

Cause - and-Effect Relationship

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

Darwin used this term to describe the ability of an organism to survive, find a mate, and produce fertile offspring.

What is fitness?

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

The idea, based on Thomas Malthus, that more offspring are produced than the environment can support.

What is overproduction (or reproductive surplus)?

500

The simple, common name for Darwin's 1859 book.

What is On the Origin of Species (or Origin of Species)?

500

The essential step in the mechanism of natural selection where inherited traits are passed from parents to offspring

500

Using engineering principles to design and create products or processes using biological systems.


Bioengineering

500

A random change in allele frequencies in a population due to chance events, especially significant in small populations.
