Which event is the most likely to cause for the four periods when punctuated equilibrium seems to have occurred?
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. "

How do scientists know that KT extinction took place?
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.
What event caused the KT extinction which killed off more than half of the world's species?

Element traced to the extinction of the dinosaurs?

When do small mammals appear in fossil records?
During the KT extinction event the majority of life on earth became extinct. Small mammals, however, were able to survive this mass extinction.
What does KT mass extinction mean?
The mass extinction that is believed to have eliminated larger dinosaurs 65 million years ago. Smaller dinosours survived, their descendants are today's reptiles. The mass extinction is believed to have been caused by an asteroid that collided with Earth. For more information, read the Wikipedia article on "Cretaceous-Paleogene extinction event", or search for this term on your favorite search engine.
What evidence of the KT boundary in Colorado has been discovered by researchers?
Researchers have found evidence of the KT boundary in Colorado, including a layer of sediment containing high levels of iridium, shocked quartz, and microtektites. These materials are characteristic of the impact event that caused the mass extinction of the dinosaurs.
Why did the microraptor become extinct?
The microraptor existed during the early Cretaceous period. It became extinct following the KT extinction event, which wiped out the majority of life on earth.
What is the KT asteroid?
It is the asteroid that hit the Earth 65 million years ago and contributed to the extinction of the dinosaurs.
