The Study of Fossils
What is Paleontology
Structures that have similar structure but different ancestry and genetics.
What are Analogous Structures
A group of organisms of the same species that are in a certain area that share a common gene pool.
What is a Population
The movement of alleles between populations.
What is Gene Flow
Study of biodiversity
What is Systematic Biology
The belief that periods of catastrophic extinctions occurred.
What is Catastrophism
A process where individuals inherited traits that tend to survive and reproduce at higher rates.
What is Natural Selection
The percentage of each allele in a populations gene pool
What is Allele Frequency
Genetic Drift that is caused by natural disasters.
What is the Bottleneck Effect
A branch of systematic biology that organizes biodiversity into related categories.
What is Taxonomy
Diagrams that reflect evolutionary relationships.
What is an Evolutionary Tree
Structures that have similar structure due to common ancestors.
What are Homologous Structures
Changes in allele frequency in a gene pool due to random chance.
What is Genetic Drift
Genetic Drift that occurs when a few individuals become isolated and form a new population.
What is the Founder Effect
An evolutionary family tree.
What is Phylogeny
They have a resemblance to two groups that are in present day that are separate.
What are Transitional fossils
The intentional breeding of organisms to try and achieve a desirable trait.
What is Artificial Selection
The equations for the Hardy-Weinberg equilibrium
p+q=1
The three types of natural selection.
Directional Selection
Disruptive Selection
Stabilizing Selection
The process of naming and organizing organisms into a taxon.
What is Classification
The two main principals of Lamark's Hypothesis
Use and disuse
Inheritance of acquired characteristics
A bacteria and virus that are resistant to antibiotics and is a form of artificial selection.
What is a Superbug
The conditions for the Hardy-Weinberg Equilibrim.
No mutations
No migration
Large gene pool
Random mating
No selection
Adaptive changes in male and females that lead to an increased ability to reproduce.
What is Sexual Selection
The three domains.
Bacteria
Archaea
Eukarya
