Recent evolution and future evolution

Mon, 2006-04-10 23:04 -- John Hawks

Wired has a short article by Annalee Newitz about recent evolutionary changes and their implications for futurists:

"I think my work is changing people's ideas about evolution, because now natural selection seems to have continued all the way up to the present day," said [Jonathan] Pritchard. "There's no reason to think it stops now."

That's why futurists like [Ray] Kurzweil are excited about Lahn and Pritchard's work -- it could lay the foundations for a new understanding of evolution that's more tolerant of the idea that humans should intervene in their own genetic transformation.

[Bruce] Lahn is comfortable with this idea. "If there's an evolutionary advantage to be had by using technology, then people will do it," he said. "People are going to start changing the game in evolution in ways Darwin never anticipated."

Trans-humanist pundit James Hughes, author of Citizen Cyborg, thinks it's time to speed up the evolutionary process.

"You can take what nature gave you, but there's no good reason to take nature as a guide for where you should go in the future," Hughes said.

Now, that's an angle I hadn't thought of, and I've been thinking about this a lot. But it does make sense -- there's nothing inviolate about being human in the way we are now, since humans keep on changing.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
