Good question...
Diversity is a good indicator of the health of ecosystem ....means ...it shows that the ecosystem provides gr8 oppurtunities and niches to sustain various kinds of like , that means various kinds of evolutionary strategies.
think about harsh ecosystems like deserts and polar regions...here biodiversity is low...why?..coz the ecosystem provides very specific niches and low oppurtunities which can be exploited only by very few strategies....
So, infact the truth is ecosystems decide biodiversity... and not the other way around...so in observing biodiversity, we can have a good idea about its ecosystem/...

Biodiversity is very important to the health of an ecosystem in many different ways, but it's rather interesting to think of the evolutionary health. Because biodiversity means the number of different species in the area, I think that you may not get the answer you expect. Biodiversity does not refer to diversity within a species. Consider these two points:
1. Biodiversity makes a community more stable. If a population in the community has a setback, usually there are other populations that can make up for it. So if one kind of food is not plentiful that year, another kind of food can take up the slack. In that way, evolutionary changes should be slowed down. That seems backwards, but evolutionary changes happen rapidly when populations are stressed. Otherwise, if populations are not stressed, there is no survival of the fittest.
2. If the ecosystem is relatively stable (as high biodiversity tends to make it) then some organisms reproduce asexually. That actually reduces the variation within the species. In that case, these populations would be less likely to evolve and more likely to stay just as they are because they already fit into their well-balanced ecosystem.

the species compete with each other to survive. If there are more types of grass eaters, the fastest ones will come out on top since the lions will eat all the slower ones and the fastest lions will get food. basically biodiversity is good for the evolutionary health of an ecosystem since it keeps all the species from overpopulating and eating all the resources and being fat and slow

it proliferates its durability and ability to support the former...where as the former forces the letter to grow...i know thats not very scientific sounding...think about it
