In the accompanying figure, note the variation in these closely related birds. What does this illustrate? hybridization macroevolution hybrid inviability adaptive radiation allometric radiation One critical requirement for life to arise on Earth was time for which to occur? The salinity of the oceans to stabilize The Earth\'s various climates to stabilize Molecules to accumulate and react with one another The atmospheric temperature to increase sufficiently The ozone layer to form, so that the level of ultraviolet radiation was reduced What is most likely to occur if a parasite accidentally introduced into the Great Lakes kills 95% of all living organisms living in the lakes? fusion in a hybrid zone evolution of a surviving organism mass extinction of the surviving organisms adaptive radiation of the surviving populations: allopatric speciation in the surviving organisms.

Solution

Answer:

7. (d) Adaptive radiation

Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches.

An example of adaptive radiation would be the avian species of the Hawaiian honeycreepers. Through natural selection, these birds adapted rapidly and converged based on the different environments of the Hawaiian islands.
