Following the Permian extinction, if there was significant continental drift, the separation of previously connected landmasses would create new isolated habitats. This geographic isolation could lead to adaptive radiation as different species evolve independently to fill the new ecological niches available in their specific environments. The increased diversity of organisms adapting to the unique conditions of each habitat could drive a new wave of speciation.
Adaptive radiation is the evolution of many diverse species from a common ancestor. After a mass extinction those individuals that were able to survive no longer have competition so they are able to colonize new habitats and occupy open niches. The individuals will undergo allopatirc and sympatirc speciation events, producing species that are not found elsewhere.
Adaptive radiation is the term for biodiversity that results from few ancestral species.

Adaptive radiations often occur after mass extinctions because the clearing of ecological niches due to the extinction of dominant species opens up opportunities for other species to diversify and occupy new habitats. This reduced competition allows for rapid evolution and the colonization of new adaptive zones, leading to a burst of speciation and diversification known as an adaptive radiation.

Adaptive Radiation :)
The six patterns of macroevolution are stasis, gradualism, punctuated equilibrium, adaptive radiation, convergent evolution, and extinction.
When the dinosaurs went extinct the mammals that were living alongside the dinosaurs underwent massive adaptive radiation. Large extinction events can give rise to niche openings for species that go through the extinction event.

Adaptive radiation is an evolutionary process in which a single ancestral species rapidly diversifies into a wide variety of forms to adapt to different environments or ecological niches. This leads to increased biodiversity as species evolve unique traits that allow them to exploit various resources or habitats. The effect of adaptive radiation can be seen in the rapid emergence of new species, as exemplified by the diversification of Darwin's finches in the Galápagos Islands or the various mammalian forms following the extinction of the dinosaurs. Overall, it contributes to the complexity and richness of ecosystems.
Adaptive radiation is believed to have occurred multiple times throughout evolutionary history, with one of the most notable events occurring after the mass extinction at the end of the Cretaceous period, around 66 million years ago. This event allowed mammals to rapidly diversify and occupy various ecological niches. Other significant instances of adaptive radiation include the diversification of Darwin's finches in the Galápagos Islands and the rapid evolution of reptiles after the Permian-Triassic extinction, approximately 252 million years ago.
An adaptive zone is an environment which allows the development of adaptive radiation.
Divergent evolution is also known as adaptive radiation.
