SMALLEST CREATURES include mycoplasma, the smallest known bacteria (300 nm), and Nanoarchaeum—smallest known archaeum (400 nm), Parvovirus—smallest known viruses (18-28 nm), Prion—smallest known infectious agent (≈10 nm), Ultramicrobacteria—possible dormant forms of larger cells (200 nm).” https://lnkd.in/eckY5qA View in LinkedIn

THE SAME SIZE AS VIRUSES. “Nanobes are about 20 nm in diameter, which may be too small to contain the basic elements for an organism to exist (DNA, ribosomes, etc.), suggesting that if they grow and reproduce they would need to do so in an unconventional way.” https://lnkd.in/eckY5qA View in LinkedIn

NOT NANOBACTERIA. “Nanobes are similar in size to nanobacteria, which are also structures that have been proposed to be extremely small living organisms. However, these two should not be confused. Nanobacteria are thought to be cellular organisms, while nanobes are hypothesized to be a previously unknown form of life or protocells.” https://lnkd.in/eckY5qA View in LinkedIn

ARE NANOBES ALIVE? “The smallest are just 20 nanometers in diameter. Some researchers believe that these structures are crystal growths, but the staining of these structures with dyes that bind to DNA might indicate that they are living organisms.” https://lnkd.in/eckY5qA View in LinkedIn

BOATLOAD OF EROSION. “Their evidence implies a culprit behind all of the missing rock: global tectonic uplift associated with the breakup of the ancient supercontinent Rodinia. This means there was probably a boatload of erosion. The timing of the GU’s formation may also help explain what triggered the so-called “snowball Earth” glaciations, an episode beginning about 720 million years ago in which much of the planet likely became covered in ice sheets.’ https://lnkd.in/ddDSSXe View in LinkedIn

WHAT IS A NANOBE? “A nanobe is a tiny filamental structure first found in some rocks and sediments. Some scientists hypothesize that nanobes are the smallest form of life, 1/10 the size of the smallest known bacteria. No conclusive evidence exists that these structures are, or are not, living organisms, so their classification is controversial.” Found 3 miles below the seabed in rocks. https://lnkd.in/eckY5qA View in LinkedIn

MASSIVE UNDERSTATEMENT. “We conclude that the Phanerozoic sedimentary record is best explained by a Great Unconformity of inherently coupled erosive and constructive genesis, with Neoproterozoic glacial erosion governing the subsequent history of continental freeboard and sediment accumulation. As such, the environmental and geochemical changes that led to the diversification of multicellular animals may be considered a direct consequence of Neoproterozoic glaciation.” https://lnkd.in/d6fatHN View in LinkedIn

"NANOBE structures have been found within organisms as well as rocks. While their existence is relatively new knowledge, some speculate that nanobes may even outnumber bacteria by an order of magnitude." https://lnkd.in/dBbSDUB View in LinkedIn

TECTONICS. “Before the plate tectonic revolution, the missing sediments from Walcott’s “Lipalian interval” were generally expected to reside in the ocean basins; their absence, along with the young age of the ocean crust, was considered a significant point of evidence in favor of seafloor spreading and plate tectonics. In a plate tectonic model, much sediment accumulated on the oceanic crust is consumed by subduction—presently at a rate of about 1.65 km3/y. Due to its low density and fusibility, however, subducted sediment in the mantle wedge is often incorporated into new arc magmas; consequently, a chemical or isotopic signature of subducted sediment (if sufficiently voluminous) may be preserved within the igneous record.” https://lnkd.in/d6fatHN View in LinkedIn

HOW WILL NASA know when it sees a new life for different than that on earth? By asking the wrong question, you risk missing the hidden answer. Water? Carbon? DNA? Probably not relevant. View in LinkedIn
