Tags & Description
Evolution
the change in the genetic makeup of a population over time and is supported by multiple lines of evidence
Evolutionary Fitness
ability of an organism to survive and produce fertile/viable offspring
Ecosystem stability
__________________ determines the rate and direction of evolution
Genetic variation
genotypic and phenotypic differences between individuals in a population
Stabilizing selection
eliminates extremes (reduces variance) and makes tall peak
Diversifying selection
extremes grow and intermediates decrease (may lead to 2 species)
Directional Selection
entire population shifts one way due to change in allele frequency
Artificial Selection
process by which humans select desirable traits in other species and selectively breed individuals with the desired traits
Convergent Evolution
process by which similar environmental conditions select for similar traits in different populations or different species over time
