    The rise and fall of ancient walruses, and how modern ones got their tusks, is a story that spans almost 20 million years. And while there are parts of the story that we’re still trying to figure out, it looks like tusks didn’t have anything to do with how or what these animals ate.

      @plentyness Old Norse hrosshvalr, ‘horse whale’, is believed to be the origin for the various Germanic language names for walruses that we use today. English being English, the language drifted really far away from anything sounding like "horse-whale" (at least to me, a native English speaker who barely knows a few words in any other languages), while it sounds like German and Norwegian both remained closer to the original word components.

      That's why we don't tend to call our cousin species as human, because we like to call ourselves that. So hominids is the common grouping.

      He wasn’t saying that the presence of humans became an active factor AT 2.6 million years ago. And he wasn’t saying that the number of walrus species crashed all at once, AT that time.
      He said that the drop-off in species diversity occurred AFTER the end of the Pliocene, which was 2.6 million years ago, and can be attributed, ultimately, to the convergence of multiple factors since that point. Not all of them emerged at the same time, and the significance of each one has waxed and waned in that 2.6 million-year period. Obviously, the impact of humans on walruses became significant later on in that period than, for example, earlier episodes of climate and sea-level change.
      He could have pedantically spelled all that out, but he’s trying to convey a lot of information concisely, and no doubt felt this audience is probably intelligent enough to connect the dots, and not have every detail explained to them like they’re six years old.

    Last year I watched the netflix series titles "Our Planet" the one thing that really stuck out for me is the damage we have done to the walrus population. We drive them into small crowded islands where they scale impossibly steep cliffs but due to their body shape they can't get down safely, and almost all that climb up loose grip while climbing down and tumble hundreds of metres onto the jagged dagger like rocks below. The number of dead bodies is absolutely horrific. I urge anyone here to go watch that series.
