What is the main difference between adaptive radiation and other forms of speciation? adaptive radiation is a mechanism for evolution. adaptive radiation happens over a relatively short time. adaptive radiation requires a founding population. adaptive radiation occurs only on islands.

The correct answer would be "Adaptive radiation happens over a relatively short time".

Adaptive radiation refers to the process of evolution in which ancestor organisms diversify rapidly into a wide variety or new forms as a result of environmental changes, availability of new resources, availability of new niches, or new challenges.

Accumulation of adaptive radiations over a long period of time results in speciation.

For example, Darwin's finches adapted according to their feeding behavior.

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
