and WONDERFUL "speech" you did...darn it wasn't REALLY from Turbine
As for the evolution thing. Evolution is nohting more than mutations that worked well in the current situation so Since one of the traits to reduce anxiety and stress was to get away from it, some of our race live in a state of "that's not happeneing" *cough cough global warming cough cough* when something can cause bad consequences, yet is a long stressful path to reverse.
........... I think you are referring to global climate Change!! We all know that global Warrming is not for real!
As for the evolution thing. Evolution is nohting more than mutations that worked well in the current situation so they didn't die out, Even the Neanderthal technically didn't disappear (when they were stronger, smarter and more adaptable, but the soon to be hom* sapiens were more savage, larger in number and had that genocide thing ingrained pretty well then as the future Saxxons,) but like the "lost" Mayans, interbreeded with their conquered into non regognition. Thank Discovery channel for showing what we may still carry even if it's not "highlighted." While evolution helped the Neo help the sapien develop so many of the basics we have now, the other branch was simply more aggressive in an age of climatic peril where the tougher literally did survive well.
It's not completely a locical flowchart but more of a river with many interscecting streams and tributaries and commerce deciding what needs to make the journey from one side to another both in value and cost effectiveness on planning the journey. Some trips are short, others are bogged down for quite a while, and sometimes our "Captain" has no clue what path they think they can take compared to the experts able to phantom the depth and direction that the current is going and will likely go (Sorry, but Kate is no Mark Twain, but more a Publisher trying to sell his stories in a common tongue when some of the technical details are not fully understood by her as they first are introduced.)
