What predictions about the fossil record does punctuated equilibrium make? In this model, what are the processes that produce rapid evolution? Which evolutionary factors are responsible for the periods of relative stasis? Patterns of punctuated equilibrium have been observed in some cases, but the debate between punctuated equilibrium and phyletic gradualism continues and provides interesting areas of research. Based on your research into the scientific process, what evidence do we see today that supports a long history of life on the planet? What evidence do we see that supports the concept of punctuated equilibrium?

Hello,
Kindly find the answers to your questions. There are quoted materials and citations.
1. What predictions about the fossil record does punctuated equilibrium make?
A sudden shift in form seen in fossil records suggesting that a change occurred in a few thousand years rather than a few million years.
2. In this model, what are the processes that produce rapid evolution?
Speciation does not occur gradually. Species exist without change for long periods of time then have an instant change. An example is the introduction of bananas to the Hawaiian islands 1000 years ago that now produced moths that feed only on bananas
3. Which evolutionary factors are responsible for the periods of relative stasis?
The Hardy-Weinberg equilibrium: Net mutation rate means the forward mutation rate does not equals the reverse mutation rate. Therefore, the environment produces the factors (favored food, water, reproduction) for periods of relative stasis. (all necessary needs are met)
4. Patterns of punctuated equilibrium have been observed in some cases, but the debate between ...
