Jonathan Last on Transformers:

Now that I have some distance, it occurs to me that Transformers is actually important in that it does something that’s never been done before–it is not just critic-proof, it is judgment proof. Michael Bay has created a work which simply cannot be held to any sort of standard: artistic, logical, moral, critical. He has made a movie which simply is. This is the Holy Grail of modern moviemaking, I think. It’s Hollywood’s version of a perpetual motion machine.

Open Source biology

How long will it take to grow plants with silicon leaves?

Whatever Carl Woese writes, even in a speculative vein, needs to be taken seriously. In his “New Biology” article, he is postulating a golden age of pre-Darwinian life, when horizontal gene transfer was universal and separate species did not yet exist. Life was then a community of cells of various kinds, sharing their genetic information so that clever chemical tricks and catalytic processes invented by one creature could be inherited by all of them. Evolution was a communal affair, the whole community advancing in metabolic and reproductive efficiency as the genes of the most efficient cells were shared. Evolution could be rapid, as new chemical devices could be evolved simultaneously by cells of different kinds working in parallel and then reassembled in a single cell by horizontal gene transfer.

But then, one evil day, a cell resembling a primitive bacterium happened to find itself one jump ahead of its neighbors in efficiency. That cell, anticipating Bill Gates by three billion years, separated itself from the community and refused to share. Its offspring became the first species of bacteria—and the first species of any kind—reserving their intellectual property for their own private use. With their superior efficiency, the bacteria continued to prosper and to evolve separately, while the rest of the community continued its communal life. Some millions of years later, another cell separated itself from the community and became the ancestor of the archea. Some time after that, a third cell separated itself and became the ancestor of the eukaryotes. And so it went on, until nothing was left of the community and all life was divided into species. The Darwinian interlude had begun.

The Darwinian interlude has lasted for two or three billion years. It probably slowed down the pace of evolution considerably. The basic biochemical machinery of life had evolved rapidly during the few hundreds of millions of years of the pre-Darwinian era, and changed very little in the next two billion years of microbia evolution. Darwinian evolution is slow because individual species, once established evolve very little. With rare exceptions, Darwinian evolution requires established species to become extinct so that new species can replace them

Now, after three billion years, the Darwinian interlude is over. It was an interlude between two periods of horizontal gene transfer. The epoch of Darwinian evolution based on competition between species ended about ten thousand years ago, when a single species, Homo sapiens, began to dominate and reorganize the biosphere. Since that time, cultural evolution has replaced biological evolution as the main driving force of change. Cultural evolution is not Darwinian. Cultures spread by horizontal transfer of ideas more than by genetic inheritance. Cultural evolution is running a thousand times faster than Darwinian evolution, taking us into a new era of cultural interdependence which we call globalization. And now, as Homo sapiens domesticates the new biotechnology, we are reviving the ancient pre-Darwinian practice of horizontal gene transfer, moving genes easily from microbes to plants and animals, blurring the boundaries between species. We are moving rapidly into the post-Darwinian era, when species other than our own will no longer exist, and the rules of Open Source sharing will be extended from the exchange of software to the exchange of genes. Then the evolution of life will once again be communal, as it was in the good old days before separate species and intellectual property were invented.

It’s been four days and four nights of nearly continuous rain, and there’s no end in sight. Bleah. Some jackass photographer called blue skies “boring.” I would really appreciate some boredom right about now. There are undoubtedly endless variations to play on the junk discs and Photoshop theme, but I’d rather get out on my bike.

Moving pictures

I’ve started yet another weblog. This one is exclusively for posting videos. YouTube is handy, but the quality is lousy. I’d like to show things I find interesting at larger sizes and higher resolution. So far, all that’s there is the opening of Denno Coil, which is one of the better examples from recent series.

For those interested in the technical stuff: The Flash player is WP-FLV, which is based on the JW FLV Player.

Update: Getting the quality I want is going to take some work. (Is it even possible to make a .flv file that isn’t jerky?) In the meantime, you can download a higher-quality Quicktime file here (12 megabyes).
