What is Ms. Johnson's new name next year?
Mrs. Wieler
100
Who developed the theory of Natural Selection?
Charles Darwin
100
__________ speciation occurs in the same location without physical barriers, usually via reproductive isolation, breeding seasons, or genetic changes
Sympatric

What is one way to determine the age of a fossil?
Carbon Dating, Radiometric Dating, Relative Dating
100
Which animal(s) do not have Jaws?
Hagfish
200
Structures that have the same functions but different structures are called...
Analogous Structure
200
What does “fitness” mean in terms of natural selection?
Most fit for the environment
200
_________ speciation occurs when geographic isolation (ex: mountains, rivers) splits a population, causing evolution in separate locations
Allopatric speciation
200
This term describes the structures that are similar due to common ancestry.
Homologous Structures
200
Primates are most closely related to what group?
Rodents
300
What type of evolution occurs when an allele is introduced into a new population through migration?
Gene Flow
300
Cacti with few spines are eaten by peccaries. Cacti with too many spines are targeted by parasitic insects. A moderate number of spines is the best balance.
Stabilizing selection
300
Finches on different islands were isolated by the sea, leading to distinct adaptations in beak shape to suit unique food sources.
Allopatric Speciation

Bird wings and butterfly wings describe what type of structuce?
Analogous
300
Which animals have retractable claws?
Leopard, Domestic Cat

What are the 8 characterisitics of life?
CHARGED R (Cells, Homeostasis, Adapt, Reproduction, Grow & develop, Energy, DNA, Respond to environment)
400
What type of selection is shown here?
Directional Selection
400
In Lake Washington, sockeye salmon have diverged into two populations: anadromous (travel to the ocean) and kokanee (stay in the lake). While in the same lake, they don't interbreed due to differences in breeding timing and size.
Sympatric Speciation
400
Describe what a vestigial structure is and give an example
non-functional or reduced body parts, organs, or behaviors that were fully functional in an organism's ancestors but have lost most or all of their original purpose through evolution (Whale pelvis, appendix, wisdom teeth)
400
Which animal(s) have feathers?
Pigeon
500
What does an enzyme do? And what macromolecule is it?
enzymes are proteins that speed up chemical reactions.
500
Male birds with either very bright blue or very dull brown plumage are more successful. The brightest are favored by females, and the dullest are non-threatening to adults, but intermediate-plumaged males are attacked and fail to mate.
Disruptive Selection
500
Type of Sympatric Speciation: Eastern and Western meadowlarks look similar, but their mating songs are distinct. Because females only respond to the song of their own species, the populations do not interbreed
Behavioral Speciation
500
This picture is depicts the development of different animals. Why does this support the theory of evolution?
It suggests that animals that develop in similar ways are more closely related.

Which animal(s) do/does NOT have hinged jaws?
Lancelet and Lamprey
