"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.
But parts of living creatures are constructed of intricate components with connections that all need to be in place for the thing to work, controlled by many genes that have to act in the proper sequence.
Thus all the right mutations (and none of the destructive ones) must happen at the same time by pure chance. To illustrate just how hopeless it is, imagine this: on the ground are all the materials needed to build a house (nails, boards, shingles, windows, etc.).
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.
"To evaluate the importance of classic sweeps in shaping human diversity, we analyzed resequencing data for 179 human genomes from four populations". You may have heard of the famous Lenski experiment. It looks for genetic changes in 12 initially identical populations of Escherichia coli bacteria that have been adapting to conditions in their flasks for over 60,000 generations.
