Study of embryo development
Embryology
When unrelated species evolve similar characteristics because they live in similar enviroments.
Convergent evolution
Study of the geographic distribution of plants and animals.
Biogeography
Speciation
Preserved remains of organisms
Fossils
Study of chemical process in living things.
Biochemistry
All of the genes available in a population.
Gene Pool
A species gradually dying out
Gradual evolution
Biological change in populations over time that make descendants genetically different from their ancestors
Evolution
(Non-random mating) traits that aren't necessary for survival but you can't reproduce without it.
Sexual Selection
Organisms that have the best traits and are more likely to live longer and reproduce more than the other organisms
Natural Selection
Changing to adapt to environment
Adaptation
Movement of genes in/out of a population
Gene Flow
Slow, constant changes over a long period of time.
Gradualism
Study of body structures to provide evidence of evolution.
Anatomy
Similar structures that suggest evidence of common ancestry.
Homologous structure
A number of different species arise from one common ancestor.
Divergent evolution
When two populations of organisms form a specialized relationship and change to each other.
Coevolution
A large event that that kills off a species
Mass extinction
There is NO change in the allele frequencies in population over time.
Genetic Equilibrium
A function that no longer has an use.
Vestigial Structures
Bursts of change followed by periods of stability
Punctuated Equilibrium
Similar structures that evolved independently in different organisms due to serving similar purposes.
Analogous structures
Study of prehistoric life through the fossil record
Paleontology
Change in gene frequency over time.
Descent with Modification
