A Berkeley site developed to promote belief in evolution has some interesting comments on recent human evolution. They suggest that evolution is now occurring at an accelerated rate, and that humans are evolving at a much more rapid pace than in past millennia. An article from Berkeley on “Understanding Evolution” offers some hypotheses about techniques investigating possible adaptations to the human genome…
When Henry Harpending of the University of Utah and his colleagues applied this technique to the genomes of people who trace their ancestry to different geographic regions (Europe, Africa, China, and Japan), what they found surprised them — lots of evidence for favorable mutations! Natural selection seems to have acted on these mutants in many different areas of our genome. In fact, the team identified more than 10,000 selection events (i.e., stretches of DNA bearing the marks of natural selection) that seem to have taken place in the past 80,000 years of human history. Interestingly, the researchers found that most of these selection events traced to the recent past, with the largest numbers having arisen in the last 10,000 years. Judging by these results, human evolution seems to have sped up: small numbers of beneficial mutations spread through human populations for most of our history, but since the end of the last ice age, we’ve experienced a renaissance of evolutionary innovation in which many new advantageous mutations arose and began to spread.(1)
Note the words “seems to have acted“, and “seem to have taken place“. It is refreshingly honest of the authors to admit the weakness of their position. Also note that the vast majority have arisen within a timetable compatible with the Bible “in the last 10,000 years”! In fact they even say that they have occurred since the Ice Age, which Creation scientists argue very convincingly, occurred soon after the flood!
Also note that in spite of 10,000 supposed mutations, in approximately the last 10,000 years, people still people look, act, walk, eat, and talk like people. We cannot dig up skeletons or look at mummies from thousands of years ago and see any evidence of these supposed mutations. In fact, for the last several thousand years of recorded history, during this time of “accelerated human evolution” nothing about human appearance or capabilities appears to have really changed.
The authors go on to say, “These results are intriguing (and controversial — they’ve already generated much discussion within the scientific community), but they do have limitations. The technique that the researchers used (looking for genomic evidence of past hitchhiking events) is reliable, but it is not particularly good at detecting very old or very recent episodes of selection.” (2)
Now note further, that the evolutionists themselves admit that the results they depend on are controversial, and have substantial limitations. Yet you will not see evidence of that uncertainty or controversy in the writings of most secular scientists, or hear it in their voices as they lecture on the supposed scientific certainty of evolution!
Nevertheless many scientists are finally admitting that research does NOT support the belief that humanity is constantly improving, getting larger or smarter or more robust. “If you had looked at Stone Age people in Europe … you would assume the trend was for people to get bigger and stronger all the time,’ said Prof Chris Stringer, of the Natural History Museum, London. ‘Then, quite abruptly, these people were replaced by light, tall, highly intelligent people who arrived from Africa and took over the world. You simply cannot predict evolutionary events like this. Who knows where we are headed?” Some scientists believe humans are becoming less brainy and more neurotic; others see signs of growing intelligence and decreasing robustness, while some, like Jones, see evidence of us having reached a standstill. All base their arguments on the same tenets of natural selection.(3)
From this we learn two things. First, these scientists who believe in evolution admit that the evidence support the sudden appearance of the modern human race (from whence they have no idea). Second, that using the exact same evidence, they come up with many different theories or explanations. Third, phrases like “you cannot predict” and “who knows” absolutely reek of conjecture, not scientific certainty! Yet they teach gullible college freshmen that they “know” evolution is a fact and creation is nonsense!
The real fact is that mere guesses and conjectures about past events that occurred many thousands of years ago are not “science”. Claiming scientific credibility is not just an overstatement, it is a complete fabrication! Wherever you look into the details at the forefront of “evolutionary science” you will find observations and conclusions that are based not on science, but on the secular atheist world view!
