When different organisms have identical/similar traits.
What is embryology?

Darwin developed some of his evolutionary ideas by studying _________.
(Hint: type of birds)
What are finches?
300
Physical or behavioral changes that prevent reproduction in an organism.
What is reproductive (behavioral) isolation?
300
A type of divergent evolution when one ancestor evolves into a variety of species through adaptation.
What is adaptive radiation?
300
Natural selection favors both extreme phenotypes in a population.
What is disruptive natural selection?

Evidence of how organisms evolved from water to land or land to water.
Transitional Fossil
400
The fossil record shows evolution because ______.
What is the characteristics of the fossils change as you go deeper?
400
Because more organisms are produced than can survive, they compete for ____.
What are limited resources?
400
DOUBLE JEOPARDY
Speciation that occurs slowly.
What is gradualism?
400
Due to similar environmental pressures, unrelated organisms evolve similar traits.
What is convergent?
400
The photo below represents this vocab word.

500
True or false : populations evolve, not individuals.
True
500
Darwin published ________ on his theory of evolution?
What is "On the Origin of Species"
500
Speciation that occurs rapidly.
what is puncuated equilibrium?
500
Evolution in which two species adapt due to changes in one another.
What is coevolution?
500
Natural selection chooses one extreme phenotype in a population.
What is directional natural selection?
500
DOUBLE JEOPARDY
Based on the cladogram what trait do the Ray-finned fish and rodents have in common?
Boney Skeleton
600
The forelimbs of humans and bats are ____________. Although they are used differently, the basic skeletal structure is the same and they are derived from the same embryonic origin. Their similarity in this regard could indicate a likely evolution from a common ancestor.This is an example of _____.
What are Homologous Structures?
600
What trait about finches led to Darwin proposing his theory of natural selection
They had different beaks depending on their food source.
600
What are the four components to Darwin's Theory of Natural selection
1 - Organisms traits are variable
2 - Traits are inheritable
3 - There is competition over limited resources
4 - Individuals with beneficial traits will be more likely to survive and reproduce
600
How are Convergent and Divergent Evolution Different?
Convergent evolution is when two species with different ancestral origins develop similar characteristics, while divergent evolution refers to when two species diverge from a common ancestor and develop different characteristics.
600
DOUBLE JEOPARDY
Any selective force or forces which push a population toward the average, or median trait.
Stabilizing Selection
600
What process is the below photo describing?
Natural Selection
9999
Explain how organisms from two different Classes can evolve to have very similar traits.
In Convergent evolution organisms living in the same environment will need the same set of adaptations.
