Scientists place 500-million-year-old gene in modern organism
Scientists watch evolution at work We are still waiting with bated breath for the day scientists resurrect the woolly mammoth. Until then, we'll have to satisfy ourselves with resurrections of ancient plants and bacteria - which may be more amazing anyway, because they're even older. The dish in the above image holds a bacterium with a 500 million-year-old gene in it. That's an era just a little while after the Cambrian explosion, when life became complex. This story starts back in 2008, when Georgia Tech researchers figured out the ancient sequence of a gene called Elongation Factor-Tu (EF-Tu), which is found in all cellular life. Bacteria need it to survive, so its ancient version presents an interesting window into genetic evolution. Bet?a?, a astrobiology postdoctoral fellow in Georgia Tech's NASA Center for Ribosomal Origins and Evolution, figured out where this ancient gene would go on modern E. coli chromosomes and in which sequence. Then Ka? produced eight identical strains of E. coli with this

It's a project 500 million years in the making. Only this time, instead of playing on a movie screen in Jurassic Park, it's happening in a lab at the Georgia Institute of Technology.

Jurassic Park in a Petri dish: Scientists recreate 500 million-year-old bacteria in lab - what could possibly go wrong?
A 500 million-year-old bacteria has been brought back to life in a laboratory at Georgia Tech - and the 'Frankenstein germ' has now grown stronger than todays's E Coli bacteria.
