The Theory of Evolution
The founder of the the theory of evolution
Who is Charles Darwin?
The total genetic info available in a population
What is the gene pool?
The movement of individuals out of a population
What is emigration?
What speciation begins with
What is isolation?
The theory that states: development of new types of organisms over time resulting in a heritable change in characteristics within a population from one generation to the next.
What is Theory of Evolution?
The measure of an individual's hereditary contribution to the next generation
What is fitness?
2 primary factors of variation
What are environmental factors and hereditary?
The process of genes moving from one population to another
What is gene flow?
2 types of isolation
1. Geographic
2. Reproductive
Ms. McNulty's middle name
What is Riley?
Darwin's 4 forces that could cause changes in organisms
1. Overproduction
2. Genetic Variation
3. Struggle to Survive
4. Differential Reproduction
3 main mechanisms for variation
What are mutation, recombination, and random pairing of gametes?
The phenomenon by which allele frequencies in a population change as a result of random events
The result of reproductive isolation
What is sympatric speciation?
A species that is intermediate between 2 species
What is a transitional species?
Structures that are closely related but do not drive from the same ancestral structure
What are analogous structures?
A random change in a gene that is passed onto offspring
What is mutation?
3 patterns of natural selection
1. Stabilizing
2. Disruptive
3. Directional
This type of isolation results from barriers to successful breeding between population groups in the same area
What is reproductive isolation?
The name of the street Ms. McNulty grew up on
What is Crestview drive?
Two or more species have evolved adaptions to each other's influence
What is coevolution?
5 assumptions that the Hardy-Weinberg Genetic Equilibrium is based on
1. No mutations
2. No leaving or entering
3. Random mating
4. Large population
5. No selection
What is directional selection?
Short periods of drastic change, including mass extinction and rapid speciation are separated by long periods of little to no change
What is punctuated equilibrium
