Oldest Fossils Ever Found Dated to 3.5 Billion Years Ago
2017-12-19 22:07:08| Extremetech
A team of researchers from UCLA and the University of Wisconsin-Madison has spent the last decade developing a process to analyze the rocks to find out if it does contain the oldest fossils in the world. The post Oldest Fossils Ever Found Dated to 3.5 Billion Years Ago appeared first on ExtremeTech.
Ancient viral 'fossils' reveal evolutionary mechanisms
2017-06-29 06:00:00| LifeSciencesWorld
[NEWS] Studying DNA fragments left by ancient viruses in their host's genome has shown even non-autonomous viruses could prosper by helping each other. By analysing ancient viral footprints in the rice genome, Hokkaido University researchers have discovered different virus species infecting the same plant helped each other by exchanging DNA. Many viruses including “pararetroviruses (PRVs)” have the ability to insert their DNA into their host's genome. I…

Miniature popcorn-like fossils illustrate environmental changes impact species
2016-06-13 07:28:00| Climate Ark Climate Change & Global Warming Newsfeed
News Nation: According to a new study, fossils resembling miniaturised popcorn that date back millions of years provide the first statistical evidence that number of species on Earth depends on how the environment changes. Research conducted at University of Southampton in UK shows that environmental changes put a cap on species richness. This was based on analysing the fossil record of microscopic aquatic creatures called planktonic foraminifera. "While the idea of infinite species on a finite Earth is clearly...
