Message: <blockquote data-quote="Fishalt" data-source="post: 94867" data-attributes="member: 228">The fruit fly experiments seem fairly awful prima facie TBH for several reasons. Firstly, it seems that fruit flies preference breeding on food consumption and what they eat affects mutational rates both:Fruit fly larvae with a noted mitochondrial DNA (mtDNA) mutation showed a pronounced increase in development when eating high carbohydrate diet of banana, but stagnated on a high protein diet of passionfruit.Conversely, fruit fly larvae without the mtDNA mutation thrived on the high protein diet, but dropped in frequency when put on carbohydrates.UNSW School of Biotechnology & Biomolecular Sciences Professor Bill Ballard, who led the study, says the research is a rare demonstration of positive selection at work in evolution.“What is unique about this study is we've identified one mutation in the mitochondrial genome, that when fed a specific diet is advantageous and causes the frequency of flies in a population cage to increase,” he says.“Then when you swap the diet back to a high protein diet, the flies with the mutation go down in numbers and the other flies without the mutation go up.”[URL unfurl="true"]https://www.unsw.edu.au/newsroom/news/2018/10/fruit-fly-study-challenges-theories-on-evolution-and-high-carb-d[/URL]The second issue is that despite your protestations about people not being able to maths, you've somehow failed to consider the obvious fact that human beings--at least in the modern sense of what we mean by that term--have been around for at least 200K years. That's a lot more generations than what is produced by a decade of fruit fly breeding. To wit:"OK, so if you get a new generation of fruit flies every other day, and you ran a 30 year long experiment, you would have 30 * 365 / 2 = 5475 generations of fruit flies. Human generations are generally taken at around 20-25 years. So, according to him, that's equivalent to about 136,875 years of human history.Well, scientists generally think that modern humans have been around for about 200,000 years. That's just modern humans. The first members of the human family are estimated at 6-7 million years ago.To put that in comparison, let's say each of these bars is 50,000 years:||| 30 year fruit fly experiment|||| Modern Humans|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Total human timeHmmm...those look just a BIT different!But wait. Has anyone actually DONE a 30 year fruit fly mutation experiment?Doing a quick check, the longest I've found mentioned for fruit fly mutation experiments that debunk evolution is a mere 600 generations. Equivalent to only a tiny 15,000 years. Less than 10% of the equivalent time modern humans have been around."Finally, you still don't really understand how evolution works. You're still operating under the false premise that mutations happen, and they arrive perfect and complete or terrible and not suited to the environment and disappear from the gene pool, and that's not how it works. Evolution can happen very slowly or relatively fast., and the vast majority of the time, mutations are slight and provide virtually no survival advantage when they first arrive. Mutations are experiments tested by environmental conditions. It is these conditions that refine or discard them.Bacteria?Linksi has the longest running evolutionary experiment on bacteria and has observed major evolutionary change, and believes he has created a new species of bacteria.[URL unfurl="true"]https://news.harvard.edu/gazette/story/2014/02/evolution-in-real-time/[/URL]</blockquote>
