Humans and why we’re not evolving.

Humans and why we’re not evolving.


Humans and why we’re not evolving.

It is unlikely that we are evolving much at present. We have removed most of the selection pressures that cause evolution. Our amazing brains have produced science and technology that have removed much of the Natural Selection that operated on our populations in the past – at least in the developed countries and increasingly in the undeveloped ones.

We have:

  • Killed off predators
  • Conquered most diseases that would previously have killed us off before we had a chance to breed
  • We have improved sanitation and clean water
  • We have gained a secure food supply.All that is killing us off early is war, accidents and selfish greed.However there is some evolution. The fact that some people choose not to have children while others have many will, in time, skew the numbers of genes in the population. Is it a worry that it is the least intelligent and least educated that are reproducing most? Probably in the long term, if it is a trend that continues. Education is probably the answer to that one.Overpopulation will lead to war, food shortage and disease. Probably a new virus will emerge to which we have no resistance. Only those with a mutation that provides immunity will survive – or maybe nobody.The only difference between all of them and us is that we will be the first to do it to ourselves through our own greed, arrogance and foolishness. So much for intelligence. Without other qualities it counts for little.Time will tell.
  • So will we evolve? Be a blip? A tiny layer in the strata of time?
  • Science has demonstrated that 99.9% of all animals that have evolved have passed into extinction.
  • But this state of affairs is a blip. It will not last. Soon the selection pressures will return with a vengeance. Our numbers have grown out of proportion and our intelligence will not outdo the threats.
  • 95% of us survive long enough to have children.

The most likely selection pressure will be a virus – though we could find ourselves victims of our own greed as we destroy the natural world on which we depend. We could precipitate a disastrous climatic change or even a radical change in our atmosphere.

I'd like to hear from you...
