What is the same species?
Organisms that can mate
with one another and
produce fertile offspring
Row 1, Col 1
What is a fossil?
The preserved remains
or traces of organisms
that lived in the past.
1,2
What is slowly?
The length of time Darwin
thought it took for species
to evolve.
1,3
What are fossils?
Remains of a once living
organisms that can be used as
evidence of a common ancestor.
1,4
What are genes?
Control traits
2,1
What is a petrified fossil?
A fossil formed when
minerals replace all or
part of an organism
2,2
What is natural selection?
The process by which
individuals that are better
adapted to their
environment are more likely
to survive and reproduce.
2,3
What are homologous structures?
Similar structures that are
evidence that two organisms
share a common ancestor.
2,4
What is a mutation?
Any change in a gene or
chromosome
3,1
What is relative dating?
Method to compare the ages
of two fossils based on
the layer of rock in
which it was found
3,2
What are the Galapagos Islands?
The location of most of Darwin’s
observations which lead to his
Theory of evolution
3,3
What are evidence of a common ancestor?
Fossils, similarities
in early development,
similarities in body structure,
DNA, and protein structure .
3,4
What is an adaptation?
A trait that helps an organism
survive and reproduce
4,1
What is 300 years?
The length of time it would take
for 30g of an element to decay to
7.5g when the half life is
150 years .
4,2
What is selective breeding?
Darwin studied this in order to
develop his theory of evolution.
4,3
What is evidence that the ancestors of
whales once walked on land?
Scientists have found fossils
of whale-like creatures
that had legs .
4,4
What are variations?
Differences between members
of the same species
5,1
What is 635 years?
The length of time it would take
for 440g of an element to decay
to 13.75g when the half life is
127 years.
5,2
What are Darwin’s observations?
The beaks of finches were
different on different islands
according to what food was
available.
5,3
What are 3 causes of natural selection?
Overproduction,
Variations,
and Competition .
