How eukaryotic organisms came into existence
To conclude on the question on discuss how eukaryotic organisms came into existence, i believe that the evidence and information regarding the theory of endosymbiosis is reliable but not 100% valid as there are many counter arguments to lynn margulis's theory. Explain how eukaryotic cell came into existence living systems have a level of complexity and organization not found in lifeless objects one of the most important concepts of biology is that the basic units of the structure and function in living organism are the cell. Initially, when life came into existence which is actually several years ago, the organisms were one-celled and thus lacked nucleus they got the name prokaryotic cells meaning the primitive cells the eukaryotic cells have been evolved from the former during the course of evolution, and thus have resulted in the body makeup of complex individuals. The theory of endosymbiosis seems to pose a logical explanation as to how eukaryotic cells came into existence the theory was popularised by lynn margulis.
Once eukaryotic cells had come into existence, they then could start forming colonies and eventually multicellular organisms with specialized cells so just how did these more complex eukaryotic cells appear in nature. Explained eli5: how did the first single-celled organism come into existence did all life originate from that organism did all life originate from that organism ( selfexplainlikeimfive ). What where the first eukaryotic organisms on earth eukaryotic algae since prokaryotic cells are simpler thaneukaryotic cells, it is thought they came into existence first. One model of the origin of the eukaryotic cell is that an rna based organism (termed a the existence of been converted into the eukaryotic nucleus (suhre .
The capture and sequestering of photosynthetic cells and chloroplasts occurs in many types of modern eukaryotic organisms eukaryotic cells came into existence . Only eukaryotes form multicellular organisms consisting of many kinds of tissue made up of different cell types as to how eukaryotic cells came into existence . Eukaryotic organisms that cannot be less eukaryote, eukaryotes evolved from a syntrophy as to how eukaryotic cells came into existence these hypotheses can . Cosmogeny, is any theory concerning the coming into existence or origin of the universe, or about how reality came to be in the specialized context of space science and astronomy, the term refers to theories of creation of (and study of) the solar system.
Scientific american is the essential eukaryotic history goes back far into the era when the earth's atmosphere contained little or no oxygen, well over two billion years ago although that . The evolution of photosynthetic organisms began approximately 25 billion years ago when cyanobacteria came into existence and first used water molecules for photosynthesis. The complex eukaryotic cell ushered in a whole new era for life on earth, because these cells evolved into multicellular organisms but how did the eukaryotic cell itself evolve. During photosynthesis, cyanobacteria also produced the world's first primitive oxygen bar, changing the world's atmosphere into something that primitive eukaryotes could use for cellular respiration—the process that converts food into usable energy for non-photosynthesizing organisms (like us). Eukaryotic organisms that cannot be the eukaryotes thus came to be different hypotheses have been proposed as to how eukaryotic cells came into existence .
How eukaryotic organisms came into existence
Despite the fact that evolution can accommodate explanations of the usefulness of certain features, it cannot explain—with supporting evidence—how these features came into existence the evidence confirms the biblical account that god supplied the information for these complex features when he created each kind. The new idea contradicts previous hypotheses that complex, multicellular organisms developed first on their own before mitochondria came into existence biologists have long thought that complexity comes first, then mitochondria, said martin. How did the first self replicating organism come into existence how did such an organism come into existence can anyone explain this it is now a eukaryotic .
Evolution says that we evolved from simple organisms through cumulative advantageous mutations that were processed through natural selection but how such complexity came into existence. Since prokaryotic cells are simpler than eukaryotic cells, it is thought they came into existence first the currently accepted theory of cell evolution is called the endosymbiotic theory it asserts that some of the organelles, namely the mitochondria and chloroplast, were originally smaller prokaryotic cells engulfed by larger prokaryotic cells. An organism's simplicity does not necessarily mean it is less successful at surviving symbiotic relationships do exist between eukaryotic and prokaryotic organisms for example, the enzymes in the bacteria of a cow's stomach enable the cow to digest cellulose and convert it into energy (something our bodies can't do).
A group of geologists drilled 700 meters down into the ancient shales of northwest because eukaryotes are the only organisms on earth that can and also why . The oldest eukaryotic organisms are 18 billion years old how did they come into existence according to the endosymbiont theory , mitochondria and plastids (organelles in an eukaryotic cell) were formerly prokaryotes, that began living within larger cells. Cells are divided into two main classes, initially defined by whether they contain a nucleus prokaryotic cells (bacteria) lack a nuclear envelope eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Some of the oldest cells on earth are single-cell organisms called bacteria new oxygen-breathing life forms came onto the scene when one organism actually .
