el sueño del pibe

Carlito's way

Un survey del Economist sobre human evolution. Pocas ideas en la historia de la humanidad han sido tan originales, simples, poderosas y no obvias como la selección natural. Digo, todo eso al mismo tiempo. En nuestra ciencia sombría las ventajas comparativas vendrían a ser lo más cercano, pero a años luz. Hasta estoy considerando poner comments a esto a ver si lo discutimos. Este comienzo me mató:

SEVEN hundred and forty centuries ago, give or take a few, the skies darkened and the Earth caught a cold. Toba, a volcano in Sumatra, had exploded with the sort of eruptive force that convulses the planet only once every few million years. The skies stayed dark for six years, so much dust did the eruption throw into the atmosphere. It was a dismal time to be alive and, if Stanley Ambrose of the University of Illinois is right, the chances were you would be dead soon. In particular, the population of one species, known to modern science as Homo sapiens, plummeted to perhaps 2,000 individuals.
