vue - The Evolution of Bacteria on a “Mega-Plate” Petri Dish (Kishony Lab)
In a creative stroke inspired by Hollywood wizardry, scientists from the Kishony Lab at HMS and Technion (www.technion.ac.il/en/) have designed a simple way to observe how bacteria move as they become impervious to drugs. The experiments are thought to provide the first large-scale glimpse of the maneuvers of bacteria as they encounter increasingly higher doses of antibiotics and adapt to survive—and thrive—in them.

Oh creationists going to hate this. Watch them bang on about "micro/ macro-evolution" or what every denial machine they have in place.
-
But they're still bacteria. Or had one of them grown an arm that we missed?
-
This comments section has reminded me of how bigoted and obnoxious atheists truly are.
You people demand respect, yet you refuse to give respect. -
so what you are saying is that if,,, lets say someone took the 1000x bacteria, and cultivated it, stored it, and repeated with all known antibacterial drugs, you could have a super mutant bacterial colony resistant to all known drugs at their disposal? and all they need are some petri dishes and some spare time.
-
Hmm, this one is strong with equivocation...Bacteria before and after supposed mutations (adaption would be a better word to use) are still bacteria. The fallacy here lies in using ''evolution' under the false notion of implied 'macro' when it truly is only 'micro'. Be honest folks with what you are reporting on. This is yet another ploy to convince people in the impossible. Create some bacteria out of inorganic material then we may have a better discussion on this. Better still, create some inorganic material out of nothing and then you will have me convinced in your fantasies...

Is this Evolution or Adaptation? Might just be semantics but i am curious to know.
-
I've came here for LS.

What makes this video a compelling illustration of the logic of evolution is that you watch entire populations and observe over a timescale easy to recognize. Evolution deniers are unable to think in terms of population-level phenomena and cannot imagine the timescale involved in human evolution.
-
There is no evidence of evolution here at all. What we see is an extinction of non resistant strains, that is not evolution that is devolution, we see no gain in genetic material no new genetic material. No proof of evolution here, just the well known and documented process of extinction. We have made thousand of species of animal life, you you surprised we are seeing the same with bacteria?
-
like I said this is not vertical speciation. This is adaptation built into the DNA packaged by God. Actually it's God's curse. single cell organisms do not become multi-celled organisms do not become more sophisticated invertebrates do not become more sophisticated vertebrates do not become segmented do not become a different genus altogether. this is sheer poppycock I don't care how many billions of years you want to speculate about its bologna
-
Wow
-
1000 times antibiotic. Good gods... o_o Can we just, please not? And adaptation over only 11 days? I'm going to go cry now. T__T
-
all the mechanisms that a species of bacteria use against a particular and their are many many antibiotics are now known at the genetic level . nothing new evolved. spontaneous mutation that regulates a preexisting gene is not and can never be called evolution. do you know what a preexisting gene is?
-
Is this an explanation for how human beings came into existence? that's what I want to know about.
-
Humans
-
I find this to be a truly scary video. All those "scary videos" on youtube dont have anything on this
-
Extremely beautiful, yet unnerving.
-
it honestly is beautiful
-
Take the strong ones and evolve them to resist other types of bacteria. At the end you will have a genetically superior e coli that cannot be killed by any antibiotics. Can the immune system still defend against it?
-
What specific Bacteria was used to "Bait" the growth?
