“It is not necessary to be large to be a perfectly good arthropod (or mollusc, come to that).”

“And there is an earlier Wilson cycle, too, a billion years old, entrapped alongside the Appalachians: the Grenville, which rises to the surface in Central Park, New York, to remind us that the human and urban is no more than foam on the sea of the past.”

“As we parted at the Natural History Museum in London, I asked Richard Fortey how science ensures that when one person goes there's someone ready to take his place.He chuckled rather heartily at my naiveté. 'I'm afraid it's not as if we have substitutes sitting on the bench somewhere waiting to be called in to play. When a specialist retires or, even more unfortunately, dies, that can bring a stop to things in that field, sometimes for a very long while.'And I suppose that's why you value someone who spends forty-two years studying a single species of plant, even if it doesn't produce anything terribly new?''Precisely,' he said, 'precisely.' And he really seemed to mean it.”

“Without death there is little innovation. Extinction - death of a species - is part and parcel of evolutionary change. In the absence of this kind of extinction new developments would not prosper. In our own history, periods when ideas have been perpetuated by dogma, preventing the replacement of old by new ideas, have also been times of stultifying stagnation. The Dark Ages in western society were the most static, least innovative of times. So the fact that trilobites were replaced by batches of successive species through their long history was a testimony to their evolutionary vigour.”

“Every new discovery about the genome is consistent with evolution having happened. Whether we find it appealing or not is another question, but personally I like being fourth cousin to a mushroom and having a bonobo as my closest living relative. It makes me feel a real part of the world.”

“The great proliferation of museums in the nineteenth century was a product of the marriage of the exhibition as a way of awakening intelligent interest in the visitor with the growth of collections that was associated with empire and middle-class affluence. Attendance at museums was as much associated with moral improvement as with explanation of the human or natural world.”
