Well, that’s how UPenn bioethicist Arthur Caplan feels about a successful experiment, announced yesterday, wherein scientists built a genome out of nearly one million nucleotides, piece by piece, from scratch, using “off-the-shelf chemicals,” and then put the genome into a hollow cell, which then came alive and replicated as normal. The world-famous genome researcher who led the project thought it was fairly earth-shattering himself.
“We think these are the first synthetic cells that are self-replicating and whose genetic heritage started in the computer. That changes conceptually how I think about life,” said J. Craig Venter, 63, who gained fame a decade ago as the co-sequencer of the human genome.
Other, less easily impressed scientists call the experiment merely a “milestone” or an “important advancement.” Meanwhile, President Obama is asking a panel to investigate whether this has the potential to destroy mankind.
