Say “No” to human intervention before it is too late

 

“Humans have stopped evolving.” I was absolutely stunned when I first heard this view, but now I realize it is true. Sir David Attenborough, the famous broadcaster for dozens of BBC documentaries on nature, warned that biological evolution in humans has ended. According to Darwin’s theory of natural selection, only animals strong enough to adapt to their environment can survive and flourish. So when advances of the modern age enable humans to raise 95 to 99 percent of our offspring, even the weakest that under most circumstances would not survive, we put a halt to natural selection.

Human intervention in the laws of nature has affected the biological evolution of the  human species in various ways. Since progress in vaccines and antibiotics can protect us, we  no  longer  adapt  to  infectious  disease  through  natural  selection.  Advances  in  transportation allow global travel and give us the potential to share our genes with anyone, thereby reducing the chance of evolutionary change. Most significantly, because much of our work can be accomplished by machines, human beings face possibly being overtaken  by apparatus with sufficient artificial intelligence. The human species is nearly “done” from  a natural selection perspective. What is looming for humans? Obviously, we must say “No” to human intervention before it is too late.
