variability, heritability, differential reproduction
1. mutation; 2. natural selection; 3. movement in/out of population; 4. small population size; 5. nonrandom mating.
1. mutations; 2. sexual reproduction (gene recombination)
Body parts that share a common function, but not structure
Migration from a location; Leaving a population
1. biogeography; 2. biochemistry; 3. embryology; 4. fossil record; 5. morphology
remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species.
Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called natural selection.
1. Genetic Mutation 2. Gene Flow (migration) 3. Genetic Drift 4. Natural Selection
features that are similar in structure but appear in different organisms and have different functions.
Genetic drift resulting from the reduction of a population, typically by a natural disaster, such that the surviving population is no longer genetically representative of the original population (type of genetic drift)
A well tested concept that explains a wide range of observations
A group of similar organisms that can breed and produce fertile offspring.
A measure of the ability to survive and produce more offspring relative to other members of the population in a given environment
A trait that helps an organism survive and reproduce. Formed via natural selection.
A process in which individuals that have certain inherited traits tend to survive and reproduce at different rates than other individuals because of those traits. Not random.
Change in allele frequencies as a result of the migration of a small subgroup of a population (type of genetic drift)
A change in the allele frequency of a population as a result of chance events rather than natural selection "survival of the luckiest"
Movement of alleles into or out of a population due to the migration of individuals to or from the population Immigration
Migration to a new location; Moving into a population
change in allele frequencies in populations over time.
A random change in DNA, ultimately creating genetic diversity
population with no genetic change (no evolution)
process in which populations of organisms become different enough that they can no longer breed and produce fertile offspring
all the alleles for a particular trait in a population
Universal genetic code that can be used as evidence of evolution between organisms.
An ancestral species from which later species evolved
All the fossils throughout the history of the Earth that are used as evidence of evolution.
Differences among members of a species.
