This thread here

>>>1967380

is what has gave idea me to.

Experiment in evolutionary genetics: What if we took some germs from the same culture, gave them a bunch of hostile environments (like antibiotics that are partially effective on them) and tried to get them to *repeat* the same selections? See if two batches of germs or more come up with the same solutions.

Has this been done?? this /sci/borg wants to know of these things.

Uranium figure is totally bullshit.

And that is a CONSERVATIVE estimate. Optimistic ones factoring in uranium recoverable from seawater put it at billions of years.

Yes, it has been done, most notably by Richard Lenski. http://en.wikipedia.org/wiki/E._coli_long-term_evolution_experiment

The speciation he got is even reproducible, which is awesome, and if you're a school teacher and can prove it he'll send you a sample so that you can observe it in your classroom.

It's been done. Look up Lenski's long term evolution experiment.

Parallely evolved strain often show phenotypic and genotypic similarities (same or similar "solutions" to the same selective pressures), but not always. Mutation is random, after all.
