I bet you never knew that the Watchtower teaches the ideas and concepts behind Evolution... only they don't use the word "evolution". They just say that the world started out with just a few hundred "kinds" of animals which all "sprung" out into the millions of different species we see today.
It is estimated that there are about 30 - 100 million species on earth and according to the bible Noah set loose all of the worlds species about 4000 years ago. For the sake of keeping things conservative I will use the value of 30 million species.
This means that every year the earth produces 7,500 new species... or 20.5 new species every single day... or almost one new species every hour of the day.
And people thought Darwin's slow evolution was absurd! He's got nothing on the Watchtower's turbo-charged evolution!

Watchtower - 1968 5/1 p.271 par.4 Making Wise Use of the Remaining Time ***Nor would his [Adam's] naming the animals take an unduly long time. The basic animal kinds could have been relatively quickly named, for when such basic kinds were taken into the ark in Noah’s day, it did not involve millions of beasts, but perhaps only a few hundred basic kinds. Thus, Adam’s naming of the animals and his realizing that he needed a counterpart would have occupied only a brief time after his creation.

Watchtower - 1957 5/15 p.316 par.16 Appreciating Basic Christian Publications***The ark was from 450 to 547 feet long (depending upon which cubit was used in measuring), 75 to 91 feet wide, and 45 to 54 feet high—a sizable structure that allowed abundant room for the various animal "kinds" described in Genesis, and from which all the varieties we now know have sprung.
