      2 questions:
      8:40 how this is possible? How that even could evolve?

      Is the mitochondria a parasite? Could be some parasite story background in primiry cells and mitochondrias fusion?

    I got rid of a "big parasite", still sucking anything and everything out of the life of my kids and I. That leech needs to get "treatment" , like years ago. I have no idea why that has not happened already. PERMANENTLY.

    We are all paracites sucking down on the earth's recources and gives iy nothimg in return

  • The sinner Jim Whitney

    There's a particular wetland near my home in West Virginia in which I've found what I feel is an inordinate amount of frogs and salamanders with additional or malformed legs, I always assumed it was due to pollution due to quite a few industrial facilities (powerhouses, steel mills, chemical plants, and natural gas compressor and metering stations) and the coal mining runoff in years past. I'm sure that has some effect, but I'd be very interested to learn whether there's a lot of that family of worms in the water. Interestingly, it's a natural wetland, but only sorta. It's along the Ohio river, and if left to nature would probably be under the river's surface almost all year, but since we built many locks and dams along the river to make it year-round navigable the river channel has become narrower and deeper, exposing the wetland to year-round air.
    Side note, how the hell does a creepy parasite video from smart folks like the SciShow crew not mention the mind-control cordyceps fungi?! Good vid just the same, I'd never heard of the frog mutating worms or the crab manipulating barnacles.

    We are the ultimate, worldwide parasite - granting billions of animals a horrible life just to take it from them and sustain ourselves longer to infect more areas. But this host of a planet will soon die
