Scientists bring 500 million-year-old bacteria back to life




A 500 million-year-old bacteria has been brought back to life in a laboratory at Georgia Tech in an experiment with echoes of Jurassic Park's disastrous recreation of the dinosaurs.

The researchers have resurrected a 500-million-year-old gene and inserted it into a modern E Coli bacteria.

The 'Frankenstein' germ has thrived. In the lab, the creation has now lived through 1,000 generations.

The scientists hope to find out whether the 'ancient' bacteria will evolve the same way it did 'first time round' - or whether it will evolve into a different, new organism.

‘This is as close as we can get to rewinding and replaying the molecular tape of life,’ said scientist Betül Kaçar, a NASA astrobiology postdoctoral fellow in Georgia Tech.

The new 'chimeric' bacteria has mutated rapidly - and some have become stronger and healthier than today's germs.

‘The ability to observe an ancient gene in a modern organism as it evolves within a modern cell allows us to see whether the evolutionary trajectory once taken will repeat itself or whether a life will adapt following a different path.’

‘The altered organism wasn’t as healthy or fit as its modern-day version, at least initially,’ said Gaucher, ‘and this created a perfect scenario that would allow the altered organism to adapt and become more fit as it accumulated mutations with each passing day.’

The growth rate eventually increased and, after the first 500 generations, the scientists sequenced the genomes of all eight lineages to determine how the bacteria adapted

This article is trying too hard. It's a gene, not a whole species of bacteria, and the study of the generational changes is hardly more interesting than the million other attempts to stimulate bacterial evolution.

The only interesting thing about this is how they were able to extract a 500 million year old gene from some dead bacteria. The article doesn't even cover that.

thats just what we need, a 500 mil year old gen mutating e coli.....

how much did they spend on their educations and they still think its a good idea?

only in america.

From all the mechanisms we know about natural selction, suspect it'll mutate differently. They didn't grow in petri dishes 500 million years ago.

If that is released into the wild, who knows how it will upset the ecosystem.

Exactly what I was thinking. If, somehow, this bacteria makes it out of the lab and into the general populous, the consequences could be dire. Or not. Who knows?
To a degree I believe it's research like this that furthers our overall understanding of where we've come from and to a lesser extent, where we're headed. On the other hand, it's research like this that scares the crap out of me, lol.

No worries as long as Tom Cruise and Bruce Willis are around.

Yeah on lists of things not to do because it may cause the extinction of the human race this is pretty far up there.
