Darwin as a religious icon

Charles Darwin portraitIt is, of course, the 200th anniversary of Charles Darwin’s birth, which is a cause for celebration if you’re of a scientific mind. But how much celebration is really appropriate? [image courtesy Wikimedia Commons]

Responding at the Guardian to artist Damien Hirst’s gushing foreword to a new edition of The Origin of Species (as well as to Darwin’s unfortunate position in the middle of the tug-o’war between fundamentalist religion and militant atheism) Andrew Brown wonders whether the pedestal on which we’ve put Darwin is too high – and whether some of his more fervent supporters, in using him as an icon against religion, have in fact made a religion of him:

treating Darwin, or any other scientist, as a wonder-worker just turns science into a priesthood. That doesn’t do anyone any good, neither scientists nor the rest of us. Darwin was a good man and his theory was a great one. But believing it, even understanding it, won’t make the goodness and the greatness rub off on the believers.

To be honest, the whole battle between the crusading atheists and their target pockets of the irrational is starting to worry me in just the same way as the fundamentalist sects. I’m an atheist myself, but I work on the principle that if I object to having someone else’s ideology crammed down my throat, they probably won’t like me doing it to them either.

And, as a matter of pragmatism, persecuting the irrationally religious does little beyond creating martyrdom, and the last thing we need is more people fixated on that.

The descent of robot: artificial evolution

wall_robotResearchers at the University of Aberdeen have developed a new method of designing complex robots using genetic algorithms:

The EA randomly creates large numbers of control “genomes” for the robot. These behaviour patterns are tested in training sessions, and the most successful genomes are “bred” together to create still better versions – until the best control system is arrived at.

MacLeod’s team took this idea a step further, however, and developed an incremental evolutionary algorithm (IEA) capable of adding new parts to its robot brain over time.

Further reading: an excellent non-fiction book that explores the idea of evolution as a general method of design is The Origin of Wealth by Eric Beinhocker.

DVD gift ideas for science-minded kids

My son, age eight, has always been interested in animals, extinct or otherwise. But he’s played to death the three-DVD documentary series The Future Is Wild, which depicts the evolution of life on Earth millions of years into the future. The CGI animation is pretty good; the extrapolated life forms in the post-human world are mind-bending.

My son doesn’t seem frightened or depressed by the depiction of a universe without human intelligence or galactic empires, which is more than I can say for his dad. You don’t have to be a kid to get into this. And if you’re even considering writing an sf story about nonhuman aliens, please see it.

There’s an animated TV adventure series on Discovery Kids, but my son and I agree that it’s not as good as the original.

Just as good, and getting almost as much screen time in my house, is Alien Planet, exploring via space probe the planet Darwin IV, where evolution produced creatures like nothing on Earth.

I hope they go over as well in your home as they have in mine.

Attack of the giant self-propelled undersea amoebas!

Sea grapes on the move make like Fred Durst - rollin', rollin', rollin'.A new discovery from the world beneath the ocean waves: a single-celled organism the size of a grape that rolls along the sea-bed like some sort of aquatic tumbleweed. [image credit Sönke Johnsen; borrowed from linked article]

The researchers said that it’s possible that the sea grape may be a descendent of the creature that made the tracks that are well known from the fossil record. Or – like the tuatara or the coelacanth – the protist could be a living fossil, that has changed little for as many as 1.8 billion years.

I.8 million years is a long time – time enough, apparently, to allow even rocks and minerals to evolve. [via SlashDot]
