Evolutions of Populations
Natural Selection
Evidences of Evolution
Adaptions/Speciation
Graphs
100
the complete set of unique alleles that would be found by inspecting the genetic material of every living member of a species or population
Gene Pool
100
Change over time
Evolution
100
Type of sequence found in the nucleus of a cell
DNA Sequence
100
Form of reproductive isolation in which 2 different populations are separated by barriers such as rivers and mountains
Geological Isolation
100
A type of selection graph with higher curve at one end than middle or opposite end.
Directional selection
200
A change in the DNA sequence that effects the genetic information.
mutation
200
Ability of an organism to survive and reproduce in a particular environment
Fitness
200
Species with different function, but similar structure
Homologous Structure
200
Isolated in time, so this is a mechanism that prevents species from mating because they breed at different times
Temporal Isolation
200
A graph with higher curve at the center than either side
stabilizing selection
300
The transfer of alleles or genes from one population to another
Genetic Flow
300
Process whereby organisms better adapted to their environment tend to survive and produce more offspring
Natural Selection
300
A human hand, whales flipper, and bats wing are examples of which type of structure
Homologous structures
300
Form of reproductive isolation in which 2 populations have different types of behavior that prevent them from interbreeding
Behavioral isolation
300
A graph with a higher curve at both sides than the middle
Disruptive selection

What is this an example of?
Explain what is going on?
This is an example of gene flow. There are two populations of birds. Population A is dominant to population B. If a bird from population A were to be introduced to population B, we would expect to see an increase of birds like in population A and decrease of birds in population B. On the other hand, if a bird from population B were to be introduced to population A, there would be no change in population A.

What did Darwin observe of the Galapagos Islands?
That many species were vastly different even though the islands were close together.( Ex.: Finches and Tortoises)
400
Three types of comparative anatomy that is used to determine common ancestry
Homologous, Analogous, and Vesitigial
400
A process within evolution that leads to the formation of new, distinct species that are reproductively isolated from one another.
Speciation
400
Both extreme phenotypes are more fit than those in the middle.
Disruptive selection

What does this image depict?
It depicts on how single-gene traits is influenced by natural selection. Specifically, lizard skin color controlled by one gene. We see a decrease of the percentage of brown lizards throughout generations 1-30, red lizards not present after the first generation, and an increase of the percentage of black lizards throughout generations 1-30.

Explain how natural selection applied to the peppered moths we spoke in class?
Before the industrial revolution, white peppered moths were able to adapt to their environment from preventing from being eaten. There was a higher percentage of white moth compared to the black peppered moths. After the industrial revolution the black smog covered tress. Therefore, Black moths were more of abundant and there was decrease in white moths.
