Module 9 Flashcards
Darwin’s postulates
Characteristics are inherited
Too many offspring are produced
The better adapted offspring survive
Source for new alleles
Mutation
Vestigial structures
Useless structures
Biogeography
Distribution of life based on barriers over time development and prices of species on different locations
Artificiall selection is also known as
Selective breeding
Convergence
Similar structures with no common ancestor
Gene pool
All alleles in a species
Allopatric speciation
Speciation because of different places
There is dispersion variance and adaptive radiation
Sympatric speciation
Speciation that happens in the same place it is usually due to chromosomal differences or reproductive barriers
Rates of speciation
Simple Darwinism and punctuated equilibria
Simple Darwinism
Slow and steady
Punctuated equilibrium
Not slow and steady
Population genetics
Genetic composition in different populations
Allele frequency
How often in the wheel appears in the population
founder effect
Event that starts with a change in allele frequency
