Adaptive radiation is usually caused by the appearance of a very useful adaptation or the appearance of a new niche in an ecological community. Both contributed to mammals' adaptive radiation. They evolved molars with four cusps, which increased their potential diet. They were insulated by fur, allowing them to survive colder areas and colder times. And the non-avian dinosaurs became extinct, allowing mammals to take their place as the (on average) largest and most dominant organisms in many ecosystems.

Adaptive Radiation is likely to produce a cluster of species in a short period of time.
When there is a sudden and long lasting change in the environment, adaptive radation will occur.
Extinction events, such as the Permian extinction and the KT extinction event. You have adaptive radiation driving evolutionary change after such events. Google " the rise of the mammals. "

It's not an English word. EXPLOSIVE means that it produces an explosion, or a sudden burst of power, like radiation and heat and force; able or likely to shatter violently or burst apart, as when a bomb explodes.
Maybe, insects have a higher LD50 for ionizing radiation than mammals do. However close in the blast or thermal flash are very likely to kill them.
an explosive eruption is more likely.
yes mammals do use internal reproduction as they are more likely to survive longer as they are less likely to be eaten.
The likely word is dynamite (early nitroglycerin-based explosive).
Conditions that could make a new island a likely place for adaptive radiation would include being near a mainland so organisms can migrate as well as geographic isolation which prevents the splinter populations from breeding with the parent population on the mainland.
They have a limited amount of radiation, but this radiation is not serious and will likely cause no harm.
