Has Human Evolution Stopped ?

Has Human Evolution Stopped ?

In this video well look at four predictions as to which way human evolution could proceed in the future.\rbr\rbrPatreon : \rbr\rbrYou can now translate this and other curious droid videos, see my video about it here \rbr\rbrHuman Evolution has stopped\rbrMany believe that because we have evolved, then its natural to assume the process will just continue like it has done since the beginnings of life over 3 billion years ago.\rbrHowever, there are some are now saying that this may not be the case for humans and that in f our own evolution may well have stopped.\rbrProponents of natural selection say that genetic innovations are only likely to become fixed in small, isolated populations. \rbrFor example, Darwins famous Galápagos finches each evolved from their mainland ancestor to fit a unique habitat on the isolated islands in the Pacific.\rbrHowever, the modern human race is now incredibly mobile and crossbreeding makes it much less likely for potentially significant mutations to become established in the gene pool.\rbrThe main way that evolution works is by natural selection or the survival of the fittest as Darwin stated but this mechanism is very much sidelined by humans because of the advances in medicine and health care.\rbrThe fittest will no longer spearhead evolutionary change, because, thanks to medical advances, the weakest also live can on and pass down their genes.\rbr\rbrHumans Will Continue to Evolve\rbrWhilst one group say human evolution is dead, Other scientists see plenty of evidence that human evolution is far from over.\rbrHere are a couple of examples that are recent adaptations which are the first steps in further evolution.\rbr1 Lose tolerance in European peoples. Normally children lose the ability to digest the lose in milk after they have been weaned. This leads to people having an intolerance to the lose which makes them feel sick if the drink milk. This is true of many people from Asia..
