This is the term for all of the ecological factors imposed in an ecosystem by nonliving things
What are abiotic factors?
(TRUE/FALSE) The first organisms on Earth were likely multicellular
What is False? - They were likely unicellular
Give an example of a vestigial strucure
What is [a vestigial structure example]?
For two organisms to be considered the same species, they must be able to create...
What is viable, fertile offspring?
This is the ordered division and naming of organisms
What is taxonomy?
This is the term for natural selection where one end of the phenotypic spectrum is selected for
What is Directional Selection?
(TRUE/FALSE) Macroevolution refers to broad patterns of evolutionary change above the species level
What is True?
Name 3 of the 6 evidences for evolution
What are fossil record, homology, analogy, transitional species, artificial selection, biogeography?
This is the term for rapid diversification of species in response to environments with a variety of ecological opportunities
What is adaptive radiation?
Taxon A is most closely related to this taxon 
What is taxon B?
This is the term for changes in allele frequencies in populations due to change and/or random events
What is Genetic Drift?
What is False? - mules are unable to reproduce
Absolute age of fossils can be determined by this kind of dating
What is radiometric dating?
Give an example of current/observable evolution
What is pesticides, herbicides, antibiotic resistance organisms, artificial selection, etc.?
A ________ or branching point is symbolic of that clade's common ancestor
What is a node?
If allele frequencies change from one generation to the next, the population is said to be doing this
What is evolving?
What is FALSE? - Populations with little genetic variation are at greater risk for extinction
This is the difference between homologous and analogous structures
What is homologous shows structural similarities between organisms that indicate common ancestry and analogous structures show similar features between organisms who do not have recent common ancestry - convergent evolution?
The first genetic material on Earth was likely this
What is RNA?
This is the difference between a phylogenetic tree and a cladogram
What is a phylogenetic tree considers more evidence and/or considers time elapsed and cladograms usually go off of one kind of trait and disregard time elapsed?

(TRUE/FALSE) Comparative Embryology shows how many organisms have very different embryological traits
What is False? - it shows how there are very similar embryological traits
What is using the same ribosomal subunits, active transport proteins, presence of DNA, Anaerobic respiration, etc.?
Speciation occurs without geographic isolation, often due to sexual selection
What is sympatric speciation?
When considering a clade, this is the species least related to the others in the tree and serves as a basis of comparison
What is an outgroup?
