An article today in Yahoo News posed the hypothesis that people are actually getting dumber.
The fact that the human race evolved from lower order animals is not deniable. The scientific line of evidence – molecular, comparative anatomy, behavioral, fossil record and ecology all converge on the same results.
About five million years ago evolutionary events set the stage for hominid development. Climate change resulted in the expansion of the savannas. The great apes, already equipped for ground travel, now found they must travel longer distances each day to forage. By four million years ago hominids were extensively bipedal.
Our early ancestors adapted to life on the savanna as opportunistic omnivores, depending on tools and skill to collect food, and some amount of thinking and reasoning ability to select safe shelters.
Australopithecus had a larger brain then the apes, but was small in comparison to today’s humans, but with large teeth and heavy jaw muscles for chewing. Hand bone fossils between two the three million years ago show a shift in the specialization of the hands from locomotion to manipulation.
Although bipedal walking existed four million years ago the brain did not evolve quantitatively until about two million years ago.
Prior to one million years ago Homo (Homo erectus) had migrated into south east Europe and central
800,000 and 200,000 years ago Homo was wide spread in Europe, Asia and Africa.
Scientists have elected to define this group as Homo
heidelbergensis. Somewhere around
600,000 years ago Neanderthal split from the sapiens line – and DNA has shown Neanderthal
to be a separate species from Sapiens with no molecular evidence of
Molecular studies have confirmed that our species, Homo sapiens, originated in
about 150,000 years ago – viewing this consensus we might all claim to be
At one time, physical strength and environmental savvy dictated the survival of the fittest. But, as the human brain developed in response to survival necessities, the need for physical strength and environmental savvy no longer held sway on life and death. Brighter and manipulative individuals advanced civilization on the backs of the uneducated and unskilled.
There have always been Kings and serfs, bosses and workers; and there have always been really stupid people that somehow survive.
Today, in the
survival stimuli hardly exist. We drive
to work, we draw our pay, we shop at Walmart, we eat our pre-prepared frozen
dinners, we watch reality TV and then we go to bed and get up and do it
again. The government actually does
take care of many of our needs. Higher
thinking skills necessary to complete our daily functions practically don’t
exist. United States
The old adage: If you don’t use it you lose it – could apply to the mental faculties of a large portion of our population. We see the far right running around with tri-corner hats and tea bags hanging from the brims; the fundamentalist religious declaring the world is six thousand years old; supposedly educated government officials claiming women can’t get pregnant as the results of rape; a large portion of the population denying climate change and declaring science as unfounded propaganda. The list can go on and on and on…but the bottom line is that we have more crazies in our population than at any point in our past.
Like Neanderthal breaking from the Sapiens line – when do we have the Darwinian split – the nut cases separating from the competent?
They might all travel to
Texas, secede from the – inbreed and
eventually create a new species: Homo Crazy.
There is no doubt that their inability to reason and process logic
would, like the Neanderthal, result in Darwinian demise. In which case, the world might be better
off. United States
