of Question #12
my most recent letter to the Watchtower Society, I made the claim
that the teaching of a global flood necessitates rates of evolution
some 16,000 times faster than what is claimed evolutionists. I arrived
at this number in this way:
- Conservative estimates put the number of mammal species at 4,000.
to the scientific community, an asteroid stuck the earth 65
- 70 million
years ago. This cataclysmic event, dubbed the K-T event (K-T boundary
in some sources), happened after mammals had already come into
existence. Its effects led to the extinction of dinosaurs and
allowed the surviving mammals to “fill freshly vacant niches”.
 Though the number of mammalian species at the time of the
K-T event was higher, for the sake of argument, my calculations
were performed assuming there was only one species of mammal at
this time. It should be noted that choosing a higher (and more
likely) number of species would tip the argument further in favor
of the evolution model.
to the Watchtower, Bible and Tract Society, the Noachian Deluge
occurred in the year 2370 B.C., giving a total time-elapse of
4,376 years from the start of the Deluge until the time of my
Watchtower Society teaches “just 43 kinds of mammals…could
have produced the great variety of species of the creatures that
are known today”. 
Taking these four bits of data, then, shows that believers in evolution
accept that the number of mammal species has increased from 2 to
4,000 during the last 65,000,000 years. Meanwhile, believers in
a literal, earth-wide Noachian Deluge must accept that the number
of mammal species has increased from 43 to 4,000 during the last
4,376 years. This means that while, on the one hand, Jehovah’s
Witnesses resolutely reject evolution, they simultaneously subscribe
to the notion that since the flood, mammals have evolved at a rate
some 16,000 times more rapidly than is taught in traditional science
To get a clearer idea of the rate at which mammals have diversified,
take a look at the graph, below.
The red line shows the average rate of evolution that literal, earth-wide
Flood believers (including Jehovah's Witnesses) must accept (whether
they realize it or not).
Since the Watchtower Society claims that each species was created
“according to their kind”, we can conclude there was
no change in the number of species prior to the Flood.  From
the time of the Flood, until now, the number of mammals must have
increased by 3,957. This works out to one new species, on average,
every 404 days (~one every 13 months).
The blue line shows the average rate of evolution taught by most
textbooks. Though it may look like a straight line, it is not; the
number of species of mammals has increased by exactly one during
the last 5,000 years. So the line does increase from 3,999
to 4,000 as it travels to the right of the graph.
The pink line rises some 16,000 times faster than the blue line.
Interestingly, reptile models would display an even greater disparity.
The Watchtower Society teaches that a mere 10 kinds of reptiles
account for the over 8,200 reptile species today,  while science
teaches that these reptiles have evolved over a period greater than
300,000,000 years.  Thus, the Watchtower Society expects its
adherents to accept the belief that reptiles diversified from 10
to 8,200 kinds in the 4,376 years from the flood even though that
would require speciation some 69,000 times faster than popular theories
on speciation, which they expect their members to reject as “serving
the purposes of Satan”.
