According to a new paper published in Science Advances life has actually evolved twice, right here on Earth. To find out, an international team of researchers led by scientists from Heinrich-Heine University in Germany investigated the origins of the suite of chemical reactions life uses to, well, exist. So to trace the origins of life, they traced the evolution of the enzymes responsible for those reactions back in time. Let’s call it by name: We are looking at one origin of the genetic code, but two origins of life.” After all, the evolution of life may be an improbable event, but if the conditions are ripe for it to happen once, why not twice?
