The more I look at it, the more and more that unguided random mutations, seem unlikely as a cause.
Not sure if we're watching the same video. Yes, there are multiple lines that extend each side, but I don't think you can argue they were "roughly the same time period" when the bacteria on the right side clearly reach each barrier (other than the first) ahead of the left side.
Pause the video at 1:03, 1:15, 1:23, and 1:34 to see what I mean.
Also, I kinda think the initial setup of the experiment with the increasing dosage sizes demonstrates that adaptation was happening. If the original strain of bacteria was already resistant to a 1000x concentration of the antibiotic, why did it keep pausing in growth when it encountered the lower strengths?
