To make any lasting change, a beneficial mutation would have to spread ("sweep") through a population and stay (become "fixed").To evolutionists, this idea has been essential for so long that it is called a "classic sweep", "in which a new, strongly beneficial mutation increases in frequency to fixation in the population."Some evolutionist researchers went looking for classic sweeps in humans, and reported their findings in the journal Science. Lenski is an evolutionary biologist who began a long-term experiment on February 24, 1988 that continues today.The top problems with evolution explained using scientific evidence against evolution.In the creation evolution controversy, it is clear not only that the theory of evolution is wrong, the theory of evolution is false, but that the theory of evolution is a lie."Evolution" mixes two things together, one real, one imaginary.It might even work if it took just one gene to make and control one part.

"In humans, the effects of sweeps are expected to persist for approximately 10,000 generations or about 250,000 years." Evolutionists had identified "more than 2000 genes as potential targets of positive selection in the human genome", and they expected that "diversity patterns in about 10% of the human genome have been affected by linkage to recent sweeps." So what did they find? to breed fruit flies that develop from egg to adult 20% faster than normal. I have simplified a report by Scott Whynot, who studied 26 peer-reviewed scientific articles authored by Dr. These papers represent the major genetic findings from 21 years of the experiment.7. coli in one of the twelve isolated populations began to utilize an energy source, citrate, that they normally could not use in the presence of oxygen. coli already have the ability to transport and metabolize citrate where there is no oxygen, but they do not produce an appropriate transport protein for an environment with oxygen. coli DNA, the gene for the citrate transporter that works without oxygen is directly upstream from genes for proteins with promoters that are active in the presence of oxygen.They exist in just about any environment: hot, cold, dry, wet, high pressure, low pressure, small groups, large colonies, isolated, much food, little food, much oxygen, no oxygen, in toxic chemicals, etc.Fruit flies are much more complex than already complex single-cell bacteria."In contrast to expectation," their test detected nothing, but they could not quite bring themselves to say it. But, as usual when breeding plants and animals, there was a down side. Genome-wide analysis of a long-term evolution experiment with Drosophila. There was an insertion mutation in a gene that represses the production of nicotinamide adenine dinucleotide (NAD), a molecule that participates in many metabolic reactions, some affecting longevity. A replication of the region happened to put the transporter gene next to one of these promoters, so it could now be expressed in the presence of oxygen.They said there was a "paucity of classic sweeps revealed by our findings". In this case the fruit flies weighed less, lived shorter lives, and were less resistant to starvation. Except for number 11, the changes found in over 60,000 generations of bacteria were due to the disruption, degradation, or loss of genetic information.But evolutionists want you to believe that changes continue, merging gradually into new kinds of creatures.
