Genes in a population
Scale of evolution
Macro evolution continued/others
Hardy - Weinbergs theorem
natural selection / others
100
Number of a specific species in a given area.
Population
100
Short period of time in which evolution occurs.
Micro-evolution
100
Species in a symbiotic relationship tend to evolve together.
Coevolution
100
Variation of the alleles in a population.
Mutation
100
Type of natural selection in which genetic diversity decreases as the population stabilizes
Stabilizing selection
200
science that focuses on the evolution within a population.
Population Genetics
200
Over geologic time: contains the results of many micro-evolution events through generations
Macro-evolution
200
The evolutionary process in which species experience changes in characteristics slowly, and incrementally.
Gradualism
200
Transfer of genetic material from one population to another.
Gene - flow
200
the change in a phenotype or genotype of a population in one direction away from the average in a particular environment over time.
Directional selection
300
all genes of all the members of a population.
Gene pool
300
The evolution of new species.
Speciation
300
The idea that evolution occurs in spurts instead of a slow, but steady path.
Punctuated equilibrium
300
Random changes that happen in a small population.
Genetic drift
300
when individuals of intermediate phenotype are less fit than those of both higher and lower phenotype, such that extremes are favored.
Disruptive selection
400
shows how many of each allele is found in the population.
Allele frequency
400
Geographic separation that does not allow species to interbreed
Allopatric Speciation
400
Differences in fitness of a group.
Natural selection
400
the phenomenon when a population has a sudden in the gene pool, due to natural environmental events.
Bottleneck - effect
400
New populations start from small groups.
Founder effect
500
the differences of phenotype in males and females.
Sexual dimorphism
500
New species that occur without geographic separation.
Sympatric Speciation
500
scientist that study's fossils.
Palaeontologist
500
Hardy Weinbergs, equation
500
The process by which humans choose individual organisms with certain phenotyes for breeding.
Artificial selection
