This experiment began in 2008. At that time biology professor Eric Gaucher managed to find an ancient gene sequences of elongation factor-Tu (EF-Tu), an important protein in E coli. EF is the most important proteins in bacteria that are found in all living cells. This section required the bacteria to survive.

Scientists NASA Astrobiology, really Kaçar can perform the difficult task of putting these ancient genes in the chromosome sequence correct. He can put the appropriate modern bacteria E coli genes.
Kaçar create eight new types of bacteria identical. This ancient gene back to life. This experiment can turn ancient genes and modern in one body safely. This bacterium was originally grew two times slower than a modern bacterium.
"Organisms that change is not as healthy as modern bacteria initially. This creates a perfect scenario that showed the organism to adapt to change and become healthier because of the accumulation of mutations every day," Gaucher said as quoted by Daily Galaxy.
Now the growth has increased after the first 500 generations. Scientists continue to see the descendants of the eight genome adaptation process. These bacteria have increased bacteria levels to match modern healthcare. In fact, several other breeds to be more healthy.
When observed more closely, scientists realized each gene is not mutated EF-Tu. But modern proteins that interact with EF-Tu is ancient in the mutated bacteria. The series of these mutations lead to rapid adaptation of bacteria that promote health.
Ancient genes have not mutated to match the modern form. However, these bacteria find the latest evolutionary step to adapt.
- Scientists achieve similar experiments the movie "Jurassic Park". Georgia Tech researchers, the U.S. turned 500 million-year-old genes in the modern bacteria E coli. One of the researchers that NASA scientists, right Kaçar. This process is called paleo evolutionary experiments. These bacteria mutate very quickly now.
