Answer:
Dessert and tundra
Explanation:
Theses two biomes get very little rain and because of this they have a less diversity of fauna and flora.
The differences are that a tundra is very dry and extremely cold and on the other hand a desert is very arid and hot and it can go as high as 54°C (130°F).
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

To show he presence of a trait you would need to follow it through multiple generations in a pedigree.
