Bill Gates on genebanks and their databases

From Bill Gates’ annual letter on the work of his foundation:

There are three things that modern agrotechnology brings to this seed improvement process. The first is simply the ability to gather plant samples from all over the world and use databases to keep track of thousands of plants grown under different conditions.

The second is sequencing and the third is transgenics, in case you were wondering. One of these days, I’d like to take Mr Gates down into Genebank Database Hell. But hey, we’re working on it. And the Foundation is helping.

How they breed Belgian Blue cattle

Swanning around the intertubes, as one does while waiting for bread to rise, I happened upon a clip from a National Geographic film called Extreme Genes. The clip gives an insight into one of the “double muscled” breeds of cattle, the Belgian Blue. You’ll note that everyone involved is at pains to point out how natural all this selection is, which is very reassuring.

Keeping up to date with taxonomy made easier

Yesterday I was invited to submit one of my photos to the Flickr pool on Systematic Botany. Yes, I know. The media ought to be alerted. But I point this out less to draw attention to my photographic prowess than to highlight the fact that there is in fact a Flickr pool on Systematic Botany, and that it is a lot of fun. Exploring the discussion forum led me to an old news item about staff at the National Museum Cardiff and Kew naming a whole bunch of new Sorbus species, and not from some isolated corner of the world either, but England and Wales.

Some of these trees have probably developed recently and are examples of on-going evolution of new species. Others are older types which have been known for some time but are only now described as ‘species’ thanks to modern DNA methods.

Some Sorbus species have economic uses, and the taxonomy is made horrendously complicated by rampant hybridization and apomixis.

Coincidentally, IIALD had a piece on a new scheme “supporting and promoting the development of persistent and openly accessible digital taxonomic literature.” I wonder whether making photographs of plants available through Flickr or some other image sharing site might contribute to this worthy cause.

Bread or beer? Why choose?

The Cartesian Dualists of the press, if not those of the hallowed groves of academe, are at it again. Der Spiegel, 1 late last month, and The Independent, late last week, report on Professor Patrick McGovern’s latest book, Uncorking the Past: The Quest for Wine, Beer and Other Alcoholic Beverages, almost entirely in terms of which came first, beer or bread.

All the familiar old arguments are trotted out. That bread is actually quite hard to make, while a forgotten soaked seed or rotten fruit is easy enough to swallow and packs enough punch for the brain to say, in Der Spiegel’s memorable phrase, “whatever that was, I want more of it!”. But this convenient opposition ignores things like porridge or gruel, both of which probably represent easier ways of consuming cereals than bread. 2 Most cereals don’t even make very good bread, at least not as it is understood by European journalists.

Professor McGovern, who runs the delightfully named Biomolecular Archaeology Laboratory for Cuisine, Fermented Beverages, and Health at the University of Pennsylavania’s Museum of Archaeology and Anthropology, is actually claiming far more than that beer came first. He seems to be laying nothing less than the development of settled agriculture, and with it civilisation as we know it, at the door of drunks. According to Der Spiegel:

[A]griculture — and with it the entire Neolithic Revolution, which began about 11,000 years ago — are ultimately results of the irrepressible impulse toward drinking and intoxication.

“Available evidence suggests that our ancestors in Asia, Mexico, and Africa cultivated wheat, rice, corn, barley, and millet primarily for the purpose of producing alcoholic beverages,” McGovern explains. While they were at it, he believes, drink-loving early civilizations managed to ensure their basic survival.

He knits together all sorts of fascinating evidential threads, and at least as far as the articles go, makes a convincing enough case. But then, I remain deeply skeptical of single explanations for anything as complex as the evolution of settled agriculture. And I suspect McGovern does too. As he told The Independent:

As for his theory on how alcohol motivated man to adopt agriculture, McGovern said: “I just wanted to put it out there as a worldwide hypothesis. Then over time maybe the different pieces can be put together from across the world.”

I’m trying really trying to avoid this, but I can’t: I’ll drink to that.
