#eukaryotes — Public Fediverse posts

Live and recent posts from across the Fediverse tagged #eukaryotes, aggregated by home.social.

  1. The earliest known #eukaryotes, the ancestors of all complex #life on Earth, lived in oxygenated, shallow marine environments nearly 1.7 billion years ago.

    The earliest eukaryotes for which we have #fossils lived in predominantly near-shore, oxygenated, benthic (on the seafloor) settings.

    This implies that the availability of #oxygen was dictating eukaryote #evolution from its early stages.

  6. How #Microbes Got Their Crawl
    #Prokaryotes arose more than four billion years ago. #Eukaryotes emerged much later, somewhere between 2.5 and two billion years ago. How complex eukaryotes evolved from simpler prokaryotes has left scientists scratching their heads for decades.
    In the oceans and on land, scientists are discovering rare, transitional organisms that bridge the gap between Earth’s simplest cells and today’s complex ones.

  16. `Through genome-wide CRISPR screening, we identified the RNA-binding protein DHX29 as a critical regulator of codon-dependent gene expression. Cryogenic electron microscopy and selective ribosome profiling demonstrated that DHX29 directly interacts with the A-site entrance of the translating 80S ribosome... These findings establish a mechanistic link between synonymous codon usage and the regulation of gene expression.`

  21. How these strange #cells may explain the origin of complex life

    #Archaea: single-celled organisms that look much like bacteria. 10ya, new group called #AsgardArchaea was identified in sediments from Atlantic. Nothing like us: They live mostly in places with little or no oxygen, and almost unbelievably ancient, perhaps 3B yr. Yet their #DNA shows they are close to humans on tree of life

If it had not occurred, there would be no great white sharks, no towering redwood trees, no hovering hummingbirds and no people. Just slimy layers of bacteria and archaea, everywhere. And the Asgard archaea may have started it all."

  35. Complex #life began to develop earlier, and over a longer span of time, than previously believed.

    Nee findings indicate that complex organisms evolved long before there were substantial levels of #oxygen in the #atmosphere, something which had previously been considered a prerequisite to the #evolution of complex life.

    The #earth is approximately 4.5 billion years old, with the first #microbial life forms appearing over 4 billion years ago.

    These organisms consisted of two groups – #bacteria and the distinct but related #archaea, collectively known as #prokaryotes.

    Prokaryotes were the only form of life on earth for hundreds of millions of years, until more complex eukaryotic cells including organisms such as #algae, #fungi, #plants and #animals evolved.

    Previous ideas on how and when early prokaryotes transformed into complex #eukaryotes has largely been in the realm of speculation. Estimates have spanned a billion years, as no intermediate forms exist and definitive fossil evidence has been lacking.

    By collecting evidence from multiple #gene families in multiple biological systems and focusing on the features which distinguish eukaryotes from prokaryotes, researchers were able to begin to piece together the developmental pathway for complex life. 

    They obtained evidence that the transition began almost 2.9 billion years ago – almost a billion years earlier than by some other estimates –  suggesting that the nucleus and other internal structures appear to have evolved significantly before #mitochondria.

    The process of cumulative complexification seems to have taken place over a much longer time period than previously thought.
