An organisms with the “best” traits (adaptations) will live longer and
reproduce more than others, causing changes in the population over time by acting on traits that are heritable
Evolution
Natural Selection
Fitness
Variation
Genes that are beneficial to the species will....
evolve a new species
will not be passed down to its' offspring
become more common over time
cause the extinction of a species
Individuals don't evolve! (a) do!
Which one does not increase variation?
Gene flow
Migration
Mitosis
Crossing Over
Which of the following is not a principle of natural selection?
Competition for resources
Older organisms are more wise
Variation via mutations
Adaptations
The goal for all species is to
(a)
When unrelated species evolve similar characteristics because they live in similar
environments
Divergent Evolution
Speciation
Convergent Evolution
Punctuated equilibrium
Speciation is when a new species is created from a
(a)
A number of different species arise from one common ancestor
- New environments caused differences to evolve in populations
Convergent Evolution
Divergent Evolution
Coevolution
Gradualism
Occurs when two populations of organisms form a specialized relationship and thus change in response to each other
Convergent Evolution
Punctuated equilibrium
Coevolution
Speciation
similar structures that suggest evidence of common ancestry
Analogous structues
Homologous structures
Vestigial structures
Natural Selection
similar structures that evolved independently in different organisms due to serving similar purposes
(a)
What is the study of prehistoric life through the fossil record?
Embryology
Paleontology
Morphology
Biogeography
What is the study of the form of living things?
Embryology
Paleontology
Morphology
Biogeography
What is the study of chemical processes in living things?
Biochemistry
Paleontology
Morphology
Biogeography
Similarities in the embryos of vertebrates early in development suggests common
ancestry among vertebrates. What study is this?
Biochemistry
Paleontology
Morphology
Embryology
This structure could be leftover from an ancestor that had used the structure, and thus could provide evidence of divergent evolution. This structure no longer has a function, but is still present.
Homologous
Analogous
Vestigial
What is the order of classification? (largest to smallest)
(a)
Binomial nomenclature is a 2-name naming system based on
Family genus
Class order
genus species
Genus species
