Bio Evolut/Taxon Tes

Evolution and taxonomy Test Reveiw

TermDefinition
On the Galapagos islands, Darwin observed: species somewhat similar to the mainland, but with traits that were suited to the island life
One of the adaptations Darwin observed was: birds different shaped beaks
Many fossil vertebrates are similar to living vertebrates because: they have a common ancestor
Artificial selection breeding animals and plants to produce offspring with desired traits
Natural selection individuals with successful traits produce more offspring and are more likely to pass those traits to the next generation
gene pool all the alleles of all the individuals of a given population
Biological fitness a measure of an individuals contribution to the gene pool of the next generation
vestigial structures remnants of structures that were important at one time but have no clear function today
Genetic drift a change in the gene pool due to chance
Darwin's theory of evolution is based on: variation and natural selection
Genetic drift changes occur because of: chance
Adaptive radiation a single species evolved into several different forms that live in different ways
The three-domain system recognizes differences between two groups of: Prokaryotes
A genus is composed of a number of related: Species
Cladogram An analysis of derived characters
Cladistic analysis shows the order in which characters evolved
All organisms in kingdoms Protista, Plantae, Fungi and Animalia are: Eukaryotes
Organisms in the domains Bacteria and Archaea were previously grouped in the kingdom: Monera
Hardy-Weinberg equilibrium allele frequencies in a population will remain constant when populations do not undergo changes to their gene pools
microevolution a generation-to-generation change in the frequencies of alleles in a population
extinct species that no longer exist
taxonomist scientist who studies the organization of living things
