Answer:
We don't truly.
Explanation:
What we do know is that they appeared around the same time on Earth:
Moles were discovered 54.8 million years ago
Rodents were discovered 54 million years ago.
If you want to compare it number wise, then moles came first.
Lets say that there is an disease or infection on a certain species, if the community was not very diverse then that whole species will be effected because they are all alike. This can lead to an extinction of that species which then leads to the a possible collapse in the community due to the change in food webs.
More diversity equals to more stability because these risks have a fewer chance of happening.
I hope all of that makes sense(;
