Is humanity facing extinction?

[M Winther]

Today the selection pressure among humans is almost extinguished. It
leads Dr. John Sanford to the conclusion that humanity faces extinction
due to the accumulative effect of mutations.

The same degenerative effect has been found among fruit flies. Removing
selection pressure leads to a 2% degeneration per generation. As a
consequence, the fruit flies become much less active and less vocal in a
few generations.

Another whistleblower is John Stevenson. He argues that the once strong
social instincts degenerate and become perverted over time. Humanity
becomes more and more socially and morally dysfunctional, leading
eventually to the collapse of society.

As far as I know, no geneticist has refuted this frightful vision. On
the contrary, it seems to follow from the accepted theory of natural
selection. Maybe Masatoshi Nei's alternative evolutionary theory can
provide a different perspective.

One of the most interesting revelations in Genetic Entropy is Dr.
Sanford’s and other workers’ analysis of the Biblical account of life
expectancies. In a statistical regression analysis of declining life
spans since Noah (lived 950 years), after 32 centuries since Noah the
life expectancy has declined to about 70. The remarkable aspect is
that this curve, which shows a sharp drop-off after Noah and a more
gradual decline about 1,000 years ago, is that it is very similar to
theoretical curves presented by other researchers that show genetic
degeneration. Either Moses faithfully recorded the events (and ages)
recorded in Genesis, or he was a skilled statistician who made up data
with a remarkable fit to an exponential curve!

None of that makes any "historical" sense, what to speak of scientific
sense. 32 centuries ago... that was roughly a century after the time
when Moses lived. And before Moses (perhaps 800 years, another 8
centuries) was Abraham. As for Noah... if my memory of the Bible
serves me right... he lived at least a "few" generations before the
time of Abraham... according to the primitive mythology and scant
genealogy in the Book of Genesis. So, even leaving aside the
ridiculous and pretentious "scientific" assertions, this religious
numbskull (Sanford, not Winther) does not even know his own Bible.

If indeed there was actually a flood like the one described in
Genesis, your average geologist would probably date it somewhere
between 6000 to 8000 years ago. That would mean that if there was an
actual person like Noah, he lived some 60-80 centuries back, and not
just 32 centuries back. And what that widely different timescale does
to Sanford's calculations is anyone's guess. At the very least his
prediction of imminent extinction is off by 3,000 to 4,000 years. :)
