I think I felt deeply at home as I read more Darwin. Thomas Huxley wrote a book called Man’s Place in Nature, and I started to know my place in nature. I was... I was happy to be a mammal and to be a vertebrate and... and to belong in a zoology book. The notion of my continuity with the animal kingdom delighted me and still delights me and the continuity, the idea of continuity was central in all of Darwin and also the idea of change by... by infinite gradation, by an infinite number of infinitesimal changes. I... I wrote a piece about Darwin and flowering plants a couple of years ago, maybe it was a bit more, and I at first thought of two other pieces. I wanted to write about Darwin and earthworms. Darwin’s last book was on earthworms. And I was doing this, I filled my kitchen with earthworms. My neighbour Neil I would bring up buckets of soil. I had worms everywhere. I... I was enchanted when Darwin has a chapter on the psychology of worms and... and how their modesty may be overcome sometimes by the force of their sexuality and then they actually couple and copulate, which is rather dangerous, on the surface of the earth instead of safe underground. And Darwin also has this amazing picture of the earth’s geography and as having been largely reshaped by... by worms. What can one worm do? Well, but if it’s a million worms or a billion worms or trillions of worms over millions of years, and it’s very difficult for human beings to grasp the idea of the infinitesimal and of slow change. But... the worm book brings this out very much, also like... like the coral reef book. One... one coral reef polyp is nothing, but you have... when you have the Great Barrier Reef in Australia, that’s a different matter. But Stephen Jay Gould had written such a beautiful essay on the Darwin of infinitesimal changes of... of worms and coral reefs, that I, you know, I... and I didn’t have a primary knowledge there, whereas I’d been immersed in botany and in fossil botany almost since boyhood.
