What is the same species?
Organisms that can mate with one another and
produce fertile offspring
1,2
The preserved remains or traces of organisms that lived in the past.
What is a fossil?
1,3
The length of time Darwin thought it took for species
to evolve.
What is slowly?
1,4
Remains of a once livingorganisms that can be used as
evidence of a common ancestor.
What are fossils?
2,1
Control traits
What are genes?
2,2
A fossil formed when minerals replace all or
part of an organism
What is a petrified fossil?
2,3
The process by which individuals that are better
adapted to theirenvironment are more likely
to survive and reproduce.
What is natural selection?
2,4
Similar structures that areevidence that two organismsshare a common ancestor.
What are homologous structures?
3,1
What is a mutation?
Any change in a gene or chromosome
3,2
Method to compare the ages of two fossils based on
the layer of rock in which it was found
What is relative dating?
3,3
The location of most of Darwin’sobservations which lead to his
Theory of evolution
What are the Galapagos Islands?
3,4
Fossils, similarities in early development,
similarities in body structure, DNA, and protein structure .
What are evidence of a common ancestor?
4,1
A trait that helps an organism survive and reproduce
What is an adaptation?
4,2
The length of time it would takefor 30g of an element to decay to
7.5g when the half life is 150 years .
What is 300 years?
4,3
Darwin studied this in order todevelop his theory of evolution.
What is selective breeding?
4,4
Scientists have found fossils of whale-like creatures
that had legs .
What is evidence that the ancestors of whales once walked on land?
5,1
Differences between membersof the same species
What are variations?
5,2

127 years.
What is 635 years?
5,3
The beaks of finches weredifferent on different islandsaccording to what food was
available.
What are Darwin’s observations?
5,4
Overproduction,Variations,
and Competition .
What are 3 causes of natural selection?
