Flashback: Creationists, this is the evidence you have to beat!In: blogarchives
During my flyfishing vacation last year, pretty much nothing was happening on this blog. Now that I’ve migrated the blog to WordPress, I can actually schedule posts to appear when in fact I’m not even at the computer. I’m using this functionality to re-blog a few posts from the archives during the month of august while I’m away. This post is from April 19, 2011:
Later, genetic evidence came along. Geneticists, with their own dating techniques and experimental methods suggested migration routes that looked something like this:
After the genetic evidence, came evidence from a bacterium associated with humans: Helicobacter pylori. It lives in our guts and can cause stomach ulcers. It’s been associated with our digestive tract for many thousands of years. Looking at the different strains of these bacteria, microbiologists, using their own dating techniques and experimental protocols, deduced that this bacterium in our guts must have traveled roughly along these routes:
Most recently, linguists came along and studied the phonemes that make up 504 of the different human languages around the globe. These linguists adopted the analysis tools from the geneticists to their own dating techniques and sampling methods and came up with a map that suggested the following main routes along which the human languages seem to have developed:
Clearly, getting the dates correct using phonemes will prove a lot harder than the previously used dating techniques. Nevertheless, these are four independent lines of evidence, collected over many decades by scientists with vastly different backgrounds and training. Yet, the results agree to an astonishing extent.
However, this doesn’t mean it’s ‘true’ or ‘scientifically proven’. It only means that this is the best humans can currently possibly do and anything new that comes along must not only explain the current congruence of disparate data, but also explain more data, than the current ‘Out of Africa’ theory can explain. A few self-contradictory passages in an ancient text do not even begin to come close to being a contender.
Given this sort of evidence, it becomes rather obvious that creationists are either uninformed or unpersuadable. For the former, information like the one in this post should be more than sufficient to falsify the creationist dogma. For the latter, ridicule and derision is the best response.
