The best evidence of such phenomena could be a population's genetic variation decrease.
When a population bottleneck occur it means that for some reason (i.e. environmental events) the size of a population is largely reduced. This leads to reduction of the genetic variation in that new smaller population. When a bottleneck occur, the founder effect is normally seen, which is that one population is established by a small group of a previously larger population leading once again the genetic variation, now though with a bigger population, to be very reduced.

Explanation:
β-lactam antibiotics are those antibiotic that that contain a beta-lactam ring (the cyclic amide with the nitrogen atom attached to the β-carbon) in their molecular structures. This class of antibiotics is the most commonly used and it includes penicillin derivatives, cephalosporins, monobactams, and carbapenems. The mechanism of action of β-lactam antibiotics is inhibition of cell wall biosynthesis in the bacteria.
