There is an anaesthetic of familiarity, a sedative of ordinariness which dulls the senses and hides the wonder of existence. For those of us not gifted in poetry, it is at least worth while from time to time making an effort to shake off the anaesthetic. What is the best way of countering the sluggish habitutation brought about by our gradual crawl from babyhood? We can't actually fly to another planet. But we can recapture that sense of having just tumbled out to life on a new world by looking at our own world in unfamiliar ways.

I could easily believe that religion could enhance health and hence survival, and that therefore there could be indeed be literally Darwinian survival value, Darwinian selection in favor of religion. None of that of course bears at all upon the truth value of the claims made by religions.

A gene might be able to assist replicas of itself that are sitting in other bodies. If so, this would appear as individual altruism but it would be brought about by gene selfishness.

You can't blame science for being used for evil purposes. What you can do is say, 'This is an exceedingly powerful tool.' And you want to make sure it is used for good purposes, not bad ones. That is a political decision.

The recurrent laryngeal nerve - which runs from the head to the voice box - goes all the way down into the chest, loops around a major artery, then goes all the way back up again. It goes right past the larynx on the way down. All a decent designer would have to do is loop it off at that point. What we're looking at is the legacy of history.

I became a little alarmed at the number of my readers who took the meme more positively as a theory of human culture in its own right - either to criticize it (unfairly, given my original modest intention) or to carry it far beyond the limits of what I then thought justified. This was why I may have seemed to backtrack.

People sometimes try to score debating points by saying, Evolution is only a theory. That is correct, but it's important to understand what that means. It is also only a theory that the world goes round the Sun - it's just a theory for which there is an immense amount of evidence. There are many scientific theories that are in doubt. Even within evolution, there is some room for controversy. But that we are cousins of apes and jackals and starfish, let's say, that is a fact in the ordinary sense of the word.
