Why is it not just as likely that there were as many small general nearly at first as now, and as great a disproportion in the number of their species?
Sentiment: NEGATIVE
The major novelty of my theory was its claim that the most rapid evolutionary change does not occur in widespread, populous species, as claimed by Most geneticists, but in small founder populations.
When I arrived on the planet, there were only two billion. Wildlife was more abundant, we were less so; now the situation is reversed.
Moreover, it thus follows that not a great deal of time was needed for the large animals of the three major parts of the world to become known to the people who spent time on the coasts of those regions.
I had found again and again that the most aberrant population of a species - often having reached species rank, and occasionally classified even as a separate genus - occurred at a peripheral location, indeed usually at the most isolated peripheral location.
Smallness in a great man seems smaller by its disproportion with all the rest.
Take the crocodile, for example, my favorite animal. There are 23 species. Seventeen of those species are rare or endangered. They're on the way out, no matter what anyone does or says, you know.
There are good reasons why natural selection has become widely accepted as an explanation of evolutionary development. When applied to mammals and other large animals, it fits perfectly. But we cannot assume that all evolutionary steps arise from selection, particularly when looking at smaller animals.
I'm saying that there were many great naturalists before Darwin's time who were very pious people and who knew more about nature than most of us. These were great naturalists; people I would admire for their knowledge of natural science given the time.
I accept extinction as best explaining disjoined species. I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families.
The fewer species there are and the fewer species we know about, the fewer questions we even know to ask.
