Evolution 1
Change over time
Evolution
Preserved remains of ancient organisms
Fossils
Proposed the theory of evolution by natural selection
Charles Darwin
Based on our current understanding of evolutionary history, the first living cells to evolve on Earth were simple, single celled organisms called:
Prokaryotes
Process that makes evolution happen
Natural Selection
Another term for Natural Selection in regards to fitness
Survival of the Fittest
The islands Darwin visited
Development of different species while they are embryos
Embryology
The two main goals of all species
Survive and reproduce
When two species evolve in response to each other
Coevolution
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
Organisms adapt to changes in
Their environment
Name one reason mutations occur
environmental causes
chance
Ostriches have wings but are unable to fly, their wings would be an example of:
Vestigial Structures
Heritable
A decrease in genetic diversity as the same alleles are passed down
Which pattern of evolution results in one species splitting into many over time?
Divergent Evolution
The field of science that studies where species are found on Earth
Biogeography
Similar structures that evolved from a common ancestor.
Homologous structures
This field of science focuses on the physical structures of organisms
Name two of the four principles of evolution
Overproduction of offspring
Variation
Adaptation
Descent with Modification
Two bodily structures, found in unrelated species, have different bone structures that serve similar purposes in each organism.
Analogous Structures
Comparing the DNA of different species would be done in this field of science.
Biochemistry
Helps an organism survive in its environment
Adaptations
