Evolution 1
Change over time
Evolution
Preserved remains of ancient organisms
Fossils
Proposed the theory of evolution by natural selection
Charles Darwin
Extinction
This is a well-tested explanation for a wide range of observations or experimental results.
scientific theory
TRUE OR FALSE: Darwin’s work on the theory of natural selection provided scientists with new interpretations of how species changed over time.
True
The islands Darwin visited
The Galapagos
If then the environment changes, what 3 things can the plants and animals living there do?
Adapt, Migrate, or die off (go extinct)
The two main goals of all species
Survive and reproduce
This describes a pattern in nature that is always true, describes what, but doesn’t explain why it happens.
scientific law
Genetic information that can be used to find relationships between organisms and prove evolution
DNA
A group of simliar organisms that can have offspring together
Species
Their environment
Process that makes evolution happen
Natural Selection
True or false: Scientific theories can one day become a law.
When a characteristic benefits an organism what happens to that characteristic?
It becomes more common.
Similar structures that evolved from a common ancestor.
Homologous structures
What units of genetic material determine what living things look like?
All the fossils throughout the history of Earth
The fossil record
What is empirical evidence?
Information gathered though observation and experimentation, its your DATA.
The main difference between Darwin's finishes found on the Galapagos islands.
Explain what happened to the peppered moth population in England and why they changed color.
The peppered moth population shifted from light gray to black due to pollution causing the trees to become darker. The light gray peppered moths stood out and were eaten more while the light gray peppered moths blended in better and were not eaten as often.
What changes did Darwin observe in finches in the Galapagos
Beaks
Genetic Variations are passed down through
Reproduction/offspring
True or False: When new information is discovered that contradicts (disproves; says is wrong) an existing theory, the existing theory is modified to include the new information.
