Artificial Life

And not the robotic kind.

Around the world, a handful of scientists are trying to create life from scratch and they’re getting closer.

Experts expect an announcement within three to 10 years from someone in the now little-known field of “wet artificial life.”

“It’s going to be a big deal and everybody’s going to know about it,” said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. “We’re talking about a technology that could change our world in pretty fundamental ways—in fact, in ways that are impossible to predict.”

What’s interesting to me is how they plan to solve some problems.

One of the leaders in the field, Jack Szostak at Harvard Medical School, predicts that within the next six months, scientists will report evidence that the first step—creating a cell membrane—is “not a big problem.” Scientists are using fatty acids in that effort.

Szostak is also optimistic about the next step—getting nucleotides, the building blocks of DNA, to form a working genetic system.

His idea is that once the container is made, if scientists add nucleotides in the right proportions, then Darwinian evolution could simply take over.

“We aren’t smart enough to design things, we just let evolution do the hard work and then we figure out what happened,” Szostak said.

This will be an interesting test of the evolution theory, but we’re years away from that.
