And because the species in question is a bacterium, scientists have been able to replay history to show how this evolutionary novelty grew from the accumulation of unpredictable, chance events.
Twenty years ago, evolutionary biologist Richard Lenski of Michigan State University in East Lansing, US, took a single Escherichia coli bacterium and used its descendants to found 12 laboratory populations.
The 12 have been growing ever since, gradually accumulating mutations and evolving for more than 44,000 generations, while Lenski watches what happens.
Mostly, the patterns Lenski saw were similar in each separate population. All 12 evolved larger cells, for example, as well as faster growth rates on the glucose they were fed, and lower peak population densities.
But sometime around the 31,500th generation, something dramatic happened in just one of the populations – the bacteria suddenly acquired the ability to metabolise citrate, a second nutrient in their culture medium that E. coli normally cannot use.
Indeed, the inability to use citrate is one of the traits by which bacteriologists distinguish E. coli from other species. The citrate-using mutants increased in population size and diversity.
...
Lenski's experiment is also yet another poke in the eye for anti-evolutionists, notes Jerry Coyne, an evolutionary biologist at the University of Chicago. "The thing I like most is it says you can get these complex traits evolving by a combination of unlikely events," he says. "That's just what creationists say can't happen." |
Another good news for science!
As always evolutionists make things up.
It had been clear for long time that E-coli used citrate:
“’Under anoxic conditions in the presence of an oxidizable cosubstrate such as qlucoseor glycerol E. coli converts citrate to acetate and succinate.” http://jb.asm.org/cgi/reprint/180/16/4160.pdf
Another good news for science, and the bad news for pseudo-science.
This is the beginning and the end of the news. As usual evolutionists only demonstrate their ignorance and deception.
There is a lot to say about the deception of “’microevolution’’ and how “’microevolution’’ proves “’macroevolution’’ (because ‘’macroevolution’’ obviously has failed long time ago).
The statement that a certain enhanced mechanism can ever distinguish any bacteria from other species is strictly designed to impose lie and deception. There is no other purpose of such a statement.
This is making an illusion that somebody in the right mind can agree with evolutionists that bacteria with different mechanism are different species, different bacterias (even if MS word does not allow such a spelling); and that bacteria is not different specie alltogether, that IT is not a separate phenomena, but IT is like in the evolutionary chain with the man, like we are one specie and bacteria is another specie and fish are 3rd species and salmon in the 4th specie and ionfish is the fifth seprate spicie--- of what???
Many more things can be said but about the article but I don’t have time. The link provided by me shows that the very base of the “experiment”’ is a deception. E-coli DO has an ability to use citrate, as the old paper proofs.
I will give you 2 more chances to link me to one justone peer reviewed publication ''observing'' microevolution.
Nobody relly reviews evolutionists anymore, so you are lucky. Shoot.
