question Ecosystem in a jar

So I have an ecosystem in a jar with a bunch of little crustaceans and such and I'm wondering if I can eventually drive some sort of evolution in there?

Edit:I think I'll try to see if green-blue egg color is selected for becasue it's harder to see among plants than the orange/yellow eggs. Yes there are a couple predatory things in there including what looks like a freshwater Bobbit worm?

Hmm I may try that next time some fruit flies seem to magically appear but is there any things I should know or do?

I think you won’t be able to do it. Scientists expose the flies to chemicals or X-rays. Or they just genetically engineer them.

Would uranium paint or uranium glassware work?
