Natural Selection
Mechanism of evolution that occurs when random change in the allele frequency happens in the population.
What is Genetic Drift?
group of organisms that can successfully interbreed and produce viable, fertile offspring.
What is a species?
Study of the form of living things.
What is morphology?
A diagram used to predict evolutionary relationships among groups of organisms.
What is a Phylogenetic Tree?
This is the city Mrs. Cannell was born in.
What is Pocatello?
"________ don't evolve, _______________ do."
What is Individuals/Populations?
One is the forming of new species while the other is the elimination of an existing species.
What is the difference between speciation and extinction?
Two macromolecules that provide evidence for evolution in the field of biochemistry.
What is Nucleic Acids and Proteins?
These are the three domains of life
-Eubacteria
-Archaea
-Eukarya
The names of Mrs. Cannell's two children.
Who are Greyson and Beckam?
These are the four principles of natural selection.
What is:
-overproduction of offspring
-variation
-adaptations
-descendants with modifications
Examples Include:
-Dolphin
-Shark
-Ichthyosaurs
What is Convergent Evolution?
These fossils play a key role in helping us piece together evolutionary history, specifically by connecting extinct to current species.
What is a transitional fossil?
True or False, Phylogenetic Trees tell us which species came from one another.
False. They only tell us which groups are most closely related and which are least closely related.
Including year, what is Mrs. Cannell's full birthdate?
04/27/1996
We get genetic variation through these three sources.
What is
-Random Mutations
-Meiosis (Crossing Over)
-Migration/Gene Flow
It is necessary for speciation to occur.
What is isolation?
A real example of direct observation in the last century that has provided evidence of evolution.
-peppered moths
-antibiotic resistant bacteria
-pesticide resistant mosquitos
What is Endosymbiosis?
This is Mrs. Cannell's "spirit animal"
What is an alligator?
-No mutations
-No natural selection
-Large population
-No migration
-Random mating
What are the 5 conditions that must be met for evolution to NOT occur?
In the movie "Evolutionary Arms Race" they talked a lot about the poisonous newt. This newt is a good example of this evolutionary patten.
What is coevolution?
-Same ancestry, different function
-Same function, different ancestry
-No function, same ancestry
-Homologous Structures
-Analogous Structures
-Vestigial Structures
The difference between taxonomy and phylogeny.
Both organize organisms into groups based on shared characteristics, but phylogeny deals with evolutionary history and heredity
On Monday Mrs. Cannell asked all classes what she says all the time. This was the most common answer.
What is Capeesh?
