"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.
"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.
Sweeps "were too infrequent within the past 250,000 years to have had discernible effects on genomic diversity." "Classic sweeps were not a dominant mode of human adaptation over the past 250,000 years." --Hernandez, Ryan D., Joanna L. Cord Melton, Adam Auton, Gilean Mc Vean, 1000 Genomes Project, Guy Sella, Molly Przeworski. Classic Selective Sweeps Were Rare in Recent Human Evolution. There were many mutations, but none caught on, and the experiment ran into the . The ability to use citrate in the presence of oxygen, trumpeted by evolutionists as a big deal, was the result of previously existing information being rearranged, not the origin of new information.
They wrote that "forward experimental evolution can often be completely reversed with these populations". Mutations that result in a gain of novel information have not been observed.
It might even work if it took just one gene to make and control one part.
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.
Evolutionists tell us we cannot see evolution taking place because it happens too slowly.
A human generation takes about 20 years from birth to parenthood.
Mutations in DNA happen fairly often, but most are repaired or destroyed by mechanisms in animals and plants.Scientists like to study them because a generation (from egg to adult) takes only 9 days. Here is how the imaginary part is supposed to happen: On rare occasions a mutation in DNA improves a creature's ability to survive, so it is more likely to reproduce (natural selection).In the lab, fruit flies are studied under every conceivable condition. That is evolution's only tool for making new creatures.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.).We tie a hammer to the wagging tail of a dog and let him wander about the work site for as long as you please, even millions of years.
