The Human Race
Came Close to Extinction in Prehistoric Times
Embracing broader scientific perspectives and new technology-based
tools, researchers have started to more effectively contrast and
relate the research and discoveries of various scientific fields.
A new hypothesis has emerged that suggests that the human race very
nearly met with extinction approximately 71,000 years ago.
In fact,
it is believed that all but the Neanderthal and modern human lineage
went extinct. What was the cause? A “volcanic winter” brought on
by the colossal and catastrophic eruption of Mount Toba in Sumatra.
(Estimated at 3,000 times greater energy than
the Mt. St .Helens eruption of 1980.)
Plumes of ash blasted into the atmosphere blocked out the sun,
triggering a “volcanic winter” that lasted roughly six years and
plunged the planet into a 1,000 year long Ice Age (estimated to be
the coldest Ice Age to ever have occurred on Earth).
The “volcanic winter” created widespread drought and famine and
brought death to the human populations around the world and also
greatly affected hominid stem-line evolution. Scientists refer to
the evolutionary impact as “the bottle neck effect.” The implication
is that the rapid and dramatic decrease in human populations brought
about a rapid differentiation (or genetic divergence) within the
surviving populations.
As conditions slowly improved, the surviving human populations were
able to grow once more and develop with some of the genetic
differences we see today.
According to this new scientific hypothesis, mankind was reduced to
a sobering and frightening level. Estimates suggest a population as
low as a mere 15,000 people existed across the entire planet.
Genetic evidence available today suggests that all living humans,
regardless of apparent diversity, are descendants of a very small
population of no more than 1,000 to 10,000 breeding pairs. Evidence
also suggests that climate improvements initially occurred around
the equator and that when the human race started to re-populate, it
fanned out from Africa and then into Asia and Europe.
