Geographical barriers such as deep ocean trenches, mountains, and isolated islands greatly influence the distribution and origin of species on Earth. This field of biology is calledMultiple choice question.ecology.paleontology.ontology.biogeography.

Biogeography is the study ofMultiple choice question.comparative anatomy of a group of closely related organisms.fossil remains or other clues to past life.the distribution of species across Earth.human artifacts and cultures in the past.

Highly specialized species tend to evolve on islands because of the environmental conditions and resource availability.Based on the theory of island biogeography, which of the following would most likely experience the greatest decline of specialist species if an invasive species emigrated from the mainland?ResponsesA small island a far distance from the mainlandA small island a far distance from the mainlandA small island in close proximity to the mainlandA small island in close proximity to the mainlandA large island a far distance from the mainlandA large island a far distance from the mainlandA large island in close proximity to the mainland

The idea that diversity in isolated habitats depends on rates of colonization and extinction is part of the equilibrium theory of what biogeography.
