You can check for the presence of an antibiotic resistance gene in a clone and then when assured it's not there, make a culture, add the antibiotic, leave to grow/die and retest any survivors. You will find the mutation which led to their survival under the new environmental selection conditions of the presence of your chosen antibiotic.
And can this technique be applied to the likes of Yialoser and Kurupet for filtration purposes?
I think GR is absolutely right! I mean on the other hand GIG might want to boast that her ancestry were monkeys - good for her, certainly not mine!
However, in biology, I must say that different species do evolve due to forces of nature in their habitat and/or mutant genetic make-up, that make them different from their normal counterparts. Living things DO NOT develop resistance to whatever is harming or destroying them! When the shit hits the fan, sometimes only the odd mutant species who might resist the conditions will survive - if not, then species will probably become extinct. If the survivors multiply and increase in number, you end up with a different breed that can survive those conditions at all times.
As for monkeys, why humans from monkeys? Why not the other way round, maybe monkeys were mutant humans that could hang from the trees and live on them eating leaves when a great flood wiped out the whole area? And survived for thousands of years until the forests were broken into by the humans and discovered their mutant offspring...
Hold on! That's a good one - I think I can become a celebrity like Darwin soon
