Best answer: Which of the following is a prediction of the geographic mosaic theory of coevolution?

The geographic mosaic theory of coevolution predicts that hot and cold spots, selection mosaics and trait remixing should result in the three major patterns of coevolution described above.

What is geographic mosaic theory of coevolution?

Geographic mosaic theory of coevolution, in ecology, the theory postulating that the long-term dynamics of coevolution may occur over large geographic ranges rather than within local populations.

Is coevolution natural selection?

Background. Interacting species sometimes impose reciprocal natural selection on each other. This process of reciprocal evolutionary change driven by natural selection is called coevolution.

What is trait remixing?

Trait remixing is the suite of processes that potentially influence the geographic distributions of alleles at gene loci underlying coevolving traits (i.e., the geographic structure of G for both species), including mutations, gene flow, genetic drift, and population extinction/recolonization dynamics.

What is coevolution in biology?

Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. The activity of each species that participates in the interaction applies selection pressure on the others.

What are examples of coevolution?

Coevolution occurs when species evolve together. Coevolution often happens in species that have symbiotic relationships. Examples include flowering plants and their pollinators.

What is geographic variation?

Geographical variation refers to differences among populations in genetically based traits across the natural geographic range of a species. Understanding the factors that give rise to and maintain geographical variation helps elucidate the causes and consequences of evolution.

Why does coevolution happen?

The term coevolution is used to describe cases where two (or more) species reciprocally affect each other’s evolution. … Coevolution is likely to happen when different species have close ecological interactions with one another. These ecological relationships include: Predator/prey and parasite/host.

What is the difference between coevolution and convergent evolution?

What is the difference between coevolution, convergent evolution, and divergent evolution? Coevolution: The mutual evolution of two different species interacting with each other. Convergent Evolution: The process by which unrelated species become more similar as they adapt to the same kind of environment.

What is reciprocal selection?

Coevolution, or reciprocal selection, is when each of two interacting species affects the fitnesses of phenotypes in the other species. Mutualistic coevolution is when both species receive a benefit from the coevolutionary relationship. This can become an obligate (required) trait.

What happens directional selection?

Directional selection: Directional selection occurs when a single phenotype is favored, causing the allele frequency to continuously shift in one direction. … The result of this type of selection is a shift in the population’s genetic variance toward the new, fit phenotype.

What are analogous structures?

Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.

What are two types of evolution?

Types of Evolution

  • Divergent Evolution. When people hear the word “evolution,” they most commonly think of divergent evolution, the evolutionary pattern in which two species gradually become increasingly different. …
  • Convergent Evolution. …
  • Parallel Evolution.

What is Allopatric in biology?

Allopatry, meaning ‘in another place’, describes a population or species that is physically isolated from other similar groups by an extrinsic barrier to dispersal. From a biogeographic perspective, allopatric species or populations are those that do not have overlapping geographic ranges (Figure 1a).
