DescriptionResearchers have discovered: evidence of primordial life in 3.95 billion years in Canadian rocks.Researchers working on a sedimentary rock formation in northern Labrador, Canada, have discovered evidence of primordial life in 3.95 billion-year-old rocks. The discovery, which is already creating scrutiny and skepticism, suggests that microbial life arose relatively quickly after the formation of our planet.The idea that life could have come so long ago and in such a strange environment is not surprising. During the Eoarquía Era, when Earth was barely 500 million years old, the landscape of our planet was full of volcanoes and its newly formed bark was still too hot to support tectonic activity. Asteroids and comets hit the surface at an inflexible rate, delivering the chemical components necessary for life. At that time, Earth's atmosphere was drowned in methane and ammonia, with no free floating oxygen to speak. Even the Sun looked different, glowing with about 75 percent of what we see today.Finding evidence of primordial life is not easy, especially since ancient rocks have been severely twisted and transformed over time. The earliest fossils date back to about 3.77 million years, but microbial organisms may also leave other traces of their existence.
