    A lot of people are asking why I said "it happened only once" and then "what about chloroplasts?" so just to make sure this is extra clear: This video focuses on mitochondrial endosymbiosis, the one event that let complex life become possible! The chloroplast came later on (but I mention them in the video anyway)

      +It's Okay To Be Smart.
      The chloroplast go back to a SECOND event of endosymbiosis that lead to the evolution of plants! And the chloroplast have a very similar function, as they also produce energy (Photosynthesis instead of Glycolysis).
      So it is wrong to say "it" heaped only once.
      Also, it is defently not the most Important step for life. Many people say that Bacteria dominante the planet, and indeed no animals nor plants would exist without bacteria. If you insist: the endosymbiosis of mitochondira might be the most important step for "complex" life.

    @chillsahoy2640 8 лет назад +21

    Just a tiny nitpick, not that it makes a huge difference to the overall argument: it is possible that many examples of endosymbiosis have taken place in the last couple of billion years, but any niches they could inhabit were already taken up by organisms (prokaryotes or eukaryotes, it doesn't really matter which) that were very well adapted to them, so new endosymbiotes die off whenever they form, leaving no trace.

    • @garethdean6382
      @garethdean6382 8 лет назад +4

      +Mr Schrödinger - I am the one who reviews. It'd be an interesting possibility. My guess would be 'No', since we see many examples of 'convergent evolution' and shred niches and organisms occupying the same niche in different environments.
      We even have many cases of bacteria residing in animal (often insect) cells, though not reduced nearly as much as mitochondria are.

    • @besmart
      @besmart  8 лет назад +69

      +BlakeMcTavishe The main reason we think it only happened once is that bacteria and archaea interact all the time today, and yet there's no evidence of this kind of thing having happened again. It just seems to be so improbable and unique that "once" is the best answer we have for the mitochondria. Now ask yourself: What does this mean for the possibility of alien life?

      +myky992 true, but if it happened after our common ancestor was allready estabelished, it would'nt be such an advantage. In fact a new type of cell during that time would have a lot of catch up to do! But that is just a guess... :)

      The rare event is the event of a prokaryote gulping up another prokaryote. The fact that the eukaryote got a second bacterium that became plants is less impressive because we already know that cell was special since it got the mitochondria already.

    Perhaps this is the answer to the Fermi Paradox.

      From wikipedia (Exponential function):
      "Exponential functions are uniquely characterized by the fact that the growth rate of such a function is directly proportional to the value of the function."
      The volume grows as the area^1.5 so it grows based on the area (not based on the volume).

If it was just a bit of machinary inside the cell they wouldn't need any genome, but the mitochondria wee see has a genome and that genome is also similar to other kinds of bacteria which suggests a relation between the two.

    I can imagine scenarios where this could have happened a billion times all over the place with the same outcome. Maybe half a billion symbiotes died before they amounted to anything and the other half finished the job.
    Or maybe this symbiosis happened but all of these new cells died and then 475.521 years later it happened again but this time they survived. Is there any proof my theory could be wrong?

      +2nd3rd1st It's definitely right, we've seen endosymbiosis start... and rapidly fail. Entire families of bacteria like wolbachia specialize in infecting cells and passing themselves along through generations. Not parasitic examples are more rare and seem only to involve animals (that we know of.) but are increasing the more we look. But nothing has approached mitochondria in how thoroughly intermingled the two partners have become.
