Here’s a zinger to mull over: The BBC has postÂed an artiÂcle about a theÂoÂry advanced by OlivÂer CurÂry, an “evoÂluÂtionÂary theÂoÂrist” workÂing out of The LonÂdon School of EcoÂnomÂics, who sugÂgests that humanÂiÂty may split into two sub-species about 100,000 years down the road. And what we’d be left with is “a genetÂic upper class” rulÂing over “a dim-witÂted underÂclass.” This is a sceÂnario, of course, that HG Wells laid out in his 1895 clasÂsic, The Time Machine (lisÂten to free audioÂbook on iTunes here). And, if CurÂry’s theÂoÂry holds water, Welles may offer the most extreme examÂple of sciÂence ficÂtion anticÂiÂpatÂing the shape of the future. Does CurÂry’s theÂoÂry have anyÂthing to it? We haven’t the fogÂgiÂest. But does it make for strangeÂly comÂpelling yet disÂturbÂing readÂing? It sure does.

I checked the calÂenÂdar. It’s not April. What’s going on?
I have to say it sounds far fetched. One of the most basic prinÂciÂples of popÂuÂlaÂtion genetÂics is that even a very litÂtle interÂbreedÂing can preÂvent evoÂluÂtionÂary diverÂgence. NatÂurÂal selecÂtion has to be pretÂty strong to overÂcome gene flow.
But — the strongest selecÂtive agent on the planÂet right now is arguably Homo sapiÂens, and as emergÂing techÂnoloÂgies allow us to manipÂuÂlate our chilÂdren’s genetÂics to suit fashÂion and ambiÂtion, maybe we’ll do to ourÂselves what we’ve already done to St. Bernards and maize.
