Understanding Evolutionary Processes

Demonstrate understanding of evolutionary processes leading to speciation

What is adaptive radiation?

• The evolution of several different species from one ancestral species.

• The study of the distribution of species and ecosystems.

• The change in the frequency of an existing gene variant in a population.

• The offspring of a mating where the parents differ in at least one characteristic.

What is allopatric speciation?

• Speciation occurring where organisms are geographically separated.

• The development of superficially similar structures in unrelated organisms.

• The process that brings about new species by eliminating less adapted individuals.

• A type of polyploidy where the multiple sets of chromosomes are derived from the same species.

Define biogeography.

• The study of the distribution of species and ecosystems.

• The evolution of several different species from one ancestral species.

• The change in the frequency of an existing gene variant in a population.

• The offspring of a mating where the parents differ in at least one characteristic.

What is the founder effect?

• When a new population is established by a very small number of individuals.

• The gradual process by which the present diversity of plants and animals arose.

• The development of superficially similar structures in unrelated organisms.

• The offspring of a mating where the parents differ in at least one characteristic.

What is natural selection?

• The process that brings about new species by eliminating less adapted individuals.

• The change in the frequency of an existing gene variant in a population.

• The offspring of a mating where the parents differ in at least one characteristic.

• The study of the distribution of species and ecosystems.

What is speciation?

• The development of one or more species from an existing species.

• The change in the frequency of an existing gene variant in a population.

• The offspring of a mating where the parents differ in at least one characteristic.

• The study of the distribution of species and ecosystems.

What is genetic drift?

• A random change in allele frequencies in a population.

• The process by which organisms better adapted to their environment tend to survive and produce more offspring.

• The development of one or more species from an existing species.

• The study of the distribution of species and ecosystems.

What is convergent evolution?

• The development of superficially similar structures in unrelated organisms.

• The evolution of several different species from one ancestral species.

• Speciation occurring where organisms are geographically separated.

• The change in the frequency of an existing gene variant in a population.

What is a bottleneck effect?

• A sharp reduction in the size of a population due to environmental events or human activities.

• The gradual process by which the present diversity of plants and animals arose.

• The offspring of a mating where the parents differ in at least one characteristic.

• The study of the distribution of species and ecosystems.
