Russell Vreeland and colleagues at West Chester University in Pennsylvania announced the resurrection of Bacillus Permians bacteria found 600 meters underground in Carlsbad, New Mexico. They are reviving in the presence of water after 250 million years, having survived all this time and two mass extinctions like spores in a salt crystal. A year later, a paper in Molecular Biology and Evolution by researchers Dan Graur and Tal Pupko raises serious and detailed doubts about the spores’ ability to survive for 250 million years, primarily because the spores do not contain active DNA repair enzymes, so the DNA is expected to decay into small fragments due to factors such as natural radioactive radiation in the soil, and the bacterium is expected to lose its viability within several hundred years at most.<\/p>\n","protected":false},"excerpt":{"rendered":"
