Summary Introduction
Introduction: The evolution of many species from a single ancestor is termed as adaptive radiation. It is a continuous process, where the diversification of species is in a common ancestral line. Species from a single ancestor can get fragmented into different subpopulations when isolated geographically and exposed to different environmental conditions. The species in a new habitat could establish their role in a new environment and become different from the common ancestor.

Students have asked these similar questions
Adaptive radiation is common following a period of mass extinction, probably because (a) the survivors of a mass extinction are remarkably well adapted to their environment (b) the unchanging environment following a mass extinction drives the evolutionary process (c) many adaptive zones are empty(d) many ecological niches are filled (e) the environment induces changes in the timing of development for many species
Perhaps 98 percent to 99 percent of all species that have ever existed areextinct. Nearly all went extinct long before humans arrived on the scene. Whyshould we be concerned about the extinction of organisms today?
Which of the following is likely a reason why evolutionary radiation would occur on islands?
A) there are many more species on islands
B) islands tend to have more favourable habitats than continents because they are moderated by the ocean
C) islands may have fewer animal and plant groups and thus provide more ecological opportunities
D) organisms can disperse easily across oceans
E) islands often have more diverse habitats than continents
