    TIL There are 30,000 free roaming bison but there are 500,000 total including privately owned and commercial herds.

    Also, like, it wasn’t just a “decision to stop” it was the end of a coincidence of factors. The mid century climatic conditions that led to several years of poor grass growth, with the combined hunting efforts of European American settlers on rail roads supported by the army’s policies against the Great Plains Indians, south eastern Indians displaced in to the great planes, and Great Plains Indians intensifying hunting via sophisticated methods they’d developed using horseback and fire arms, all driven by a demand for buffalo hides for use in industrial machinery. The end of the bad climatic conditions and the collapse of the hide trade due to development of other industrial materials is what stoped the over hunting.

    With the pressures of hunting decreased and a historic climatic event over, the population was able to rebound somewhat, but, due to the encroachment of farms and ranching never really recover. Also the genetic bottleneck of the population probably hasn’t helped things but that’s not super well studied.

    semi-serious question: i think almost every species extinct in recent history can be brought back to live with genetic engineering?

      Not really.

      First of all, because we would need the DNA of those animals. Sure, you can cobble some shit together, to make an animal that looks like that extinct species, but it would not actually be that extinct species.

      Another issue is the biome/niche that species lived in. They either went extinct because of changes to their environment, or, they went extinct, and that caused changes in their environment. So if you want to bring the species back, you also need to make sure they have a suitable environment to survive in.

      You also can’t just bring back one. A population needs generic diversity to adapt and survive. So to de-extinct a species, you need to bring back like 25 generically varied examples. Much more work than just creating a single specimen.

      Behavior matters for a species as well. If orcas went extinct in the wild, and we bought them back with a breeding program in zoos and aquarium and just released those solitary orcas into the wild, do you think they would act like orcas? Would they hunt with the same techniques? I think the pack mentality would be gone, their “language” would be gone, and I don’t think they would survive.

      The reality is, extinction is a permanent thing. We may possibly have the ability to bring a species “back” but there will be permanent, population-altering irreversible effects from going extinct in the first place.

    Because they finally caged the velociraptor in the middle image?

    The decision to stop was required, but a ton of work was done to help the population rebound. What kind of misguided message is this trying to send?

      It’s trying to tell people who think it’s too much work to bother that it’s not. I do it all the time, like when I have to wash the dishes and I tell myself “I’ll just wash one dish” because I know if I do that I’ll be a lot more motivated to continue, but if I keep looking at the whole problem before I start, I’ll be too overwhelmed to do anything at all.

      Sure, the bison population is 0.05% of what it once was. And now that we’re not actively attempting to extinct them, everything is hunky dory and no more work is needed.

      I don’t know how else to interpret this. It sounds like the Bison Society would rather be a society dedicated to literal anything else. The Kick the Can Down the Road Society, perhaps.

    Each of the bison shapes in the 60mil example are actually clusters of bison so small you can’t see them with the naked eye.

      Apparently there is a certain amount of inbreeding with cattle, but several large herds without any interbreeding with cattle are closely managed to prevent inbreeding.
