What did Darwin call Natural Selection
Survival of the Fittest
The process where the breeder selects the best trait is called?
Artificial Selection
What is the name of the book that Darwin wrote?
The Origin of Species
Hutton & Lylle both said what about the formation of the earth?
The earth is millions of years old/the earth was formed by geologic forces
The 2 guys that came up with a mathematical equation that can predict allele frequencies?
Hardy & Weinberg
All of the genes in a population is called?
Gene Pool
Name 2 sources of genetic variation.
Mutations Crossover (Gene Shuffling)
Any organ that is reduced in function that may have been used by an ancestor?
Vestigial Organ
Body structures that are similar in structure and function?
Homologous Structures
Body structures that are similar in function but different in structure are called?
Analogous Structures
A trait controlled by more than one gene is called?
Polygenic Trait
A random change in allele frequencies over the generations is called?
Genetic Drift
When allele frequencies remain constant it is called?
Genetic Equalibrium
What occurs when allele frequencies in a group of migrating individuals are by chance not the same as that of the original population?
Founder Effect
What effect can happen when a population’s numbers undergoes a drastic decrease?
Bottleneck Effect
Where individuals with favorable traits survive & pass on those traits to their offspring?
Natural Selection
When natural selection favors one extreme phenotype or the other.
Directional selection
When natural selection doesn’t favor either extreme phenotype.
Stabilizing selection
When natural selection favors both extreme phenotypes.
Disruptive selection
What are the 5 conditions to maintain genetic equilibrium
1. Must be random mating 2. Must have a large pop. Size 3. No movement of genes 4. No mutations 5. No Natural selection
The evolution of a new species
Speciation
When 2 populations become separated by a geographic barrier (river, mtn. etc)
Geographic Isolation
When a species doesn’t recognize another species as a mate because it didn’t do the correct mating dance or call or make the correct display
Behavioral Isolation
When 2 species mate at different times
Temporal Isolation
When members of a population can no longer interbreed with the rest of the population is called?
Reproductive Isolation
Large scale evolution that takes place over a long period of time
Macroevolution
What percentage of species that lived on earth have become extinct?
99%
Where two or more species originate from one species called a common ancestor.
Divergent Evolution
Where 2 different species evolve in response to one another.
Coevolution
What is it called when 2 different species inhabit similar environments and evolve similar traits.
