Evolution Review

_____ is a trait may develop quickly example: antibiotic resistancePhysiological AdaptationAny body structure that is reduced in function is known as a _______Vestigial structure______ is the splitting of 1 species into 2 or morespeciationSimilarities in structure and arrangementlikeness indicates a genetic relationship through a common ancestor is known as ______Homologous structuresWhich type of genetic drift is caused by catastrophic events like a natural disaster or habitat loss?Bottleneck effectWhat is the random effect that can occur when a small population settles in an area separated from the rest of the population and interbreeds, producing unique allelic variations?Founders effectA brown mouse blends in with his surroundings. This is an example of ________Camouflage

List a vestigial structure in humans.Wisdom teethAppendixEar musclesChange in allele frequencies in a gene pool due to chance is known as _______Genetic DriftTwo organisms live in close proximity, but rarely interact due to living in different habitats. This is known as __________ isolation.HabitatThe environment acted directly on organisms to produce hereditary change in relation to need, use or disuse is known as _____________Acquired Traits_____ is the process in which a large population declines in number, then reboundsBottleneck effectWhat type of evolution happens in a shorter amount of time?MicroevolutionWhos theory was based on the idea that the environment acted directly on organisms to produce hereditary change in relation to need, use or disuse.LamarkWhen one organism looks like a dangerous organism, this is a structural adaptation called_____.mimicry

___________ is a change in the gene pool of a population in response to various stimuli exhibited by a species OVER TIMEEvolutionIt is impossible for a monkey and a lion to reproduce. This is known as____ isolation.mechanicalWhich type of evolution requires speciation?Macroevolution__________ may arise over many generations (Ex: mimicry and camouflage)Structural adaptationsTwo species are separated by an ocean. This is referred to as_________ isolation.Geographic _________ is evolutionary change below the level of species, and refers to changes in the frequency within a population or a species of its alleles MicroevolutionWhat is the name of the ship where Darwin did his studies for his evolution theory?HMS BeagleTwo species of frogs live in close proximity, but reproduce at different times of the year. This is known as ___________ isolation.Temporal__________ is any evolutionary change at or above the level of species.

MacroevolutionWhat organism did Darwin use to base a lot of his evolutionary ideas? FinchesTwo species of birds, meadowlarks, have overlapping ranges and are similar in appearance, but their songs separate them. This is known as_________ isolation.BehavioralIf a lion and a tiger mate, their offspring is a liger. The liger is sterile and cannot reproduce. This is known as________ isolation.GameteAny trait that aids the chances of survival and reproduction of an organism is known as __________Adataption
