![]() ![]() And so maybe we shouldn't rule out the chances with decent, careful lab work and developing techniques." How to not lose track of our tracksĭr. "I think it shows that the things that maybe were previously dismissed as being impossible may not be impossible. Herridge made sure to highlight one of the paper co-authors, Patrícia Pečnerová, whose ingenious lab techniques made sequencing the DNA possible. "It shows that you can get genetic information way, way, way further back in time that we previously thought was possible." She points out that while the cold conditions of the permafrost helped preserve the DNA, the sheer age of the samples is groundbreaking nonetheless. Herridge said this DNA was especially valuable because the last million years were a key period for understanding the course of mammal evolution. "To me, it's just like a proper game changer!" However, for Herridge, it was the age of the DNA that got her most excited, which has broad implications for paleontology, archaeology and a number of adjacent fields, she said.
