Again and again in recent years evolutionary biologists have found themselves returning to the theme of parasites. As Is Richard Dawkins put it in a recent paper: "Eavesdrop [over] morning coffee at any major centre of evolutionary theory today, and you will find 'parasite' to be one of the commonest words in ti the…
A gazelle on the African savanna is trying not to be eaten by cheetahs, but it is also trying to outrun other gazelles when a cheetah attacks. What matters to the gazelle is being faster than other gazelles, not being faster than cheetahs. (There is an old story of a philosopher who runs when a bear charges him and…
Man masters nature not by force but by understanding. rhis is why science has succeeded where magic failed: because it has looked for no spell to cast over nature. The alchemist and the magician in the Middle Ages thought, and the addict of comic strips is still encouraged to think, that nature must be mastered by a…
What is remarkable about man is not the size of his brain, no greater than that of a dolphin, nor his loose incomplete development as a social animal, nor even the faculty of speech or his ability to use tools. Man is remarkable because by the combination of all these things he has created an entirely new entity. When…
Senator Fowler nodded. "One other little point, Charlie. Just how often do your reproductive castes breed, anyway?" It was Jock who answered. When Charlie hesitated, David Hardy watched with interest-was there communication by gesture? "When they are allowed to," the alien said smoothly. "Don't yours?" "Eh?" "You…
But what good does it do me to think of the universe as an unthinking mechanism vast beyond comprehension? It gives me the consolation of believing I conceive it as it really is. It makes me thankful that I can conceive it at all. I could have been a pair of ragged claws, scuttling across the floors of silent seas. In…
On this planet, and probably countless more, inanimate atoms became molecules which formed cells and over billions of years those cells evolved into complex organisms which finally became viruses, plants, animals, salamanders, banyan trees and human beings. Without giving it any thought, with no way to think it, the…
I prefer sociobiologist E. O. Wilson's view of us as unfortunate tribal carnivores that have acquired intelligence. Our evolution is more like that of social insects; the advances in knowledge and understanding that we prize are more a property of the human nests we call civilization than of its individual members…
Since there is nothing to know about god, a comedian knows as much about god as any one else. An atheist however is alone in knowing that there is nothing to know so probably has the edge. An Atheist comedian can make people laugh about belief or lack of it. A good atheist comedian can make people laugh AND think…
These Republican leaders have not been content with attacks on me, or my wife, or on my sons. No, not content with that, they now include my little dog, Fala. Well, of course, I don’t resent attacks, and my family doesn’t resent attacks, but Fala does resent them. You know, Fala is Scotch, and being a Scottie, as soon…
My father dealth a little bit with energy and used the term after I got a little bit of the idea about it. What he would have done I know, because he did in fact essentially the same thing--though not the same example of the toy dog. He would say, "It moves because the sun is shining," if he wanted to give the same…
During the Second World War the hydrophone network set up by the United States Navy to protect the entrance to Chesapeake Bay was temporarily made useless when, in the spring of 1942, the speakers at the surface began to give forth, every evening, a sound described as being like 'a pneumatic drill tearing up…
Perhaps society will become more forgiving of drunken Facebook pictures in the way Gosling says he expects it might. And some may welcome the end of the segmented self, on the grounds that it will discourage bad behavior and hypocrisy: it
So presently to bed and to sleep, but not at once to sleep. At first my brain, like a dog in unfamiliar quarters, must turn itself round for a time or so before it lies down
In a curious way, the colors of marine animals tend to be related to the zone in which they live. Fishes of the surface waters, like the mackerel and herring often are blue or green; so are the floats of the Portuguese men-of-war and the azure-tinted wings of teh swimming snales. Down below the diatom meadows and…
