On the whole, it might be easier to conclude that the timing is somewhat off than that complex life started without oxygen. But symbiosis is an intriguing theory nonetheless.
Smallest propeller on Earth powers fastest life form?
Researcher: “M. villosus swims at a speed of about 500 body lengths per second,” said Dr. Lavinia Gambelli, of Exeter’s Living Systems Institute (LSI)… “At first glance, this does not seem much. But in comparison, a cheetah achieves only 20 body lengths per second – so if an M. villosus cell had the size of a cheetah, it would swim at approximately 3,000 kilometers per hour.”
Oldest known archaea microbes found at 3.42 billion years ago?
Life seems to have got started as soon as the planet cooled. Curiously, unlike bacteria, Archaea do not cause disease in humans.
Michael Flannery on non-Darwinian discoverer of the Archaea, Carl Woese
Woese as “scarred revolutionary”? He had to fight hard to get the Archaea, the third kingdom of life, accepted. He regretted that he had not succeeded in overthrowing “the hegemony of the culture of Darwin.”
Archaea microbes have genes like flexible slinkies
They were only discovered in 1977 and they get more unusual all the time: Microbes called archaea package their genetic material into flexible shapes that flop open in unusual ways, Howard Hughes Medical Institute (HHMI) Investigator Karolin Luger reports March 2, 2021, in the journal eLife. “Very much to our surprise, we found that these Read More…
Archaea discoverer Carl Woese’s theological reflections in old age
It’s a good question whether Woese would have recognized the Archaea for what they were, had he not been in the habit of thinking for himself. Maybe he would have just been satisfied to shoehorn them into the conventional scheme somewhere.
Claim: The tree of life may have only two major branches
The slingshot of life? According to this version of the tale, the eukaryotes are descended from the Asgard archaea.
Archeon life form eats fragments of meteorites
At ScienceAlerts: This particular mineral connoisseur loves to dine on far more exotic rocks – ones that come from space.
Culturing a tentacled archean in a lab shows eukaryote-like genes from 2 billion years ago
Also, here’s a 2017 Abstract from Nature, noting that “Our results expand the known repertoire of ‘eukaryote-specific’ proteins in Archaea, indicating that the archaeal host cell already contained many key components that govern eukaryotic cellular complexity.” Thus they had that complexity back then. Not so good for Darwinism unless Darwinism is magic.
Life form’s environment is so extreme it has never been cultivated in a laboratory
The more we know, the more insights we can have, sure. But it’s not always clear what specific things truly extreme life forms can tell us about the more common ones. Maybe the message is more general, that life forms try their hardest to survive every circumstance. But what is it they have that rocks don’t?
Nature editor’s five best 2018 books include two of our favs
When Nature’s Books and Arts editor Barbara Kiser’stop five for 2018 came out, #s 1 and 2 were Lost in Math: How Beauty Leads Physics Astray by Sabine Hossenfelder on the troubled state of theoretical physics, of which Kiser says, Lost in Math is a firecracker of a book—a shot across the bows of theoretical physics.
