Our Universal Ancestor LUCA –“Common to Alien Life Beyond Earth”

Enceladus

 

“I think that if we find life elsewhere it’s going to look, at least chemically, very much like modern life,” says evolutionary biologist William Martin at the Heinrich Heine University in Düsseldorf, Germany. “Among the astrobiological implications of our LUCA paper is the fact that you do not need light. It’s chemical energy that ran the origin of life, chemical energy that ran the first cells and chemical energy that is present today on bodies like Enceladus.”

DNA Discovery –“A Clue to Emergence of Advanced Life Billions of Years Ago?”

 

“If life exists on other planets, presumably one would expect it to be microbial. Could it ever have made this transition to complex life?” said Nigel Goldenfeld, Swanlund Chair of Physics at the University of Illinois and Carl R. Woese Institute for Genomic Biology. “It’s not that you’re inevitably going to get advanced life, because there are a bunch of things that have to happen.”

“Sentinel Species of the 6th Mass Extinction” –Marine Mammals May Not Survive the Anthropocene

 

 

“Marine mammals, such as manatees or bottlenose dolphins, are sentinel species—the canary in the coal mine,” says Nathan Clark,  associate professor in Pitt’s Department of Computational and Systems Biology, and the Pittsburgh Center for Evolutionary Biology and Medicine. “If you follow their health, it will tell you a lot about potential environmental issues that could eventually affect humans.”

“Alien Invasion” –99% of the Microbes Inside the Human Body are Unknown to Science

 

“There was something else, too – something weirder. Of all the non-human DNA fragments the team gathered, 99 percent of them failed to match anything in existing genetic databases the researchers examined. We found a whole new class of human-infecting ones that are closer to the animal class than to the previously known human ones, so quite divergent on the evolutionary scale.”
