Quote:I think you're missing the point. The bacteria are all the same species at the beginning (the same strain) and none of the original strain were able to survive in the antibiotic. Bacteria reproduce by splitting themselves in half, making an almost identical copy of themselves, so unless these resistant bacteria were introduced externally somehow (which is certainly a possibility that I suspect they looked into / controlled for), they must have come from the original strain after several generations.What the fuck? Seriously?
If the original strain was not resistant to the antibiotic, and some of the strain's descendants are, that means they evolved the ability to resist the antibiotic at some stage, through a mutation.
I understand that they are all the same species (a form of E. Coli) I believe. My point was to minimize the initial genetic diversification within the starting group. Bacteria are highly adaptable, and the changes are more pronounced under stress. I'm not saying that it definitely isn't evolution (change over time). But I think that there are other possibilities.
While I would like more trials, I did re-watch the video; and there are two samples here on either side. If you watch, while the left side falls behind a little, and there is a definitive spot in the middle which struggles near the end, they for the most part keep up with each other. I would predict, that this would be repeatable, as to the point I made previously.
If The Flintstones have taught us anything, it's that pelicans can be used to mix cement.
