    Kangaroos hop because they can store a lot of energy in there Achilles tendon and use that to propel them forward without using much energy. It’s good for covering long distances over flat terrain while using as little energy as possible , which is good for the Australian outback as they hop between small patches of vegitation separated by miles of desert. It’s not that good for ambushing or quickly chasing prey in a rainforest like the t rex is probably doing.

    There’s also the issue of scale, a t rex’s Achilles tendon would have to be stronger then steel cable and as stretchy as rubber to store and re use that much kinetic force from its weight.

    1 and 2 I think have pretty good consensus. The Bering land bridge opened about 10,000 years ago while the Polynesians didn’t reach Hawaii until 900 ad, so if they got to South America it was probably after that. There is some speculation that some separate group of people crossed over even before them since evidence shows that the south American coast became populated very quickly after the Bering bridge opened. Like they got to South America before they got to the interior of north America. That could be because the Rockies are large and without the fish that those people were probably eating, or it could be that some very early people, millennium before the Polynesians domesticated coconuts, made the crossing. That theory of very far in the realm of speculation but it’s a fun theory.

    According to wikipedia this is the less likely and imo less interesting explanation. They did find coconuts that are genetically distinct from the ones the Spanish brought over from the Philippines, but those ones are more distantly related to the ones in polynesia so they probably didn’t float over. Instead they are more likely evidence of pre-columbian contact of Polynesians with south and central America, along with sweet potatoes originating in South America but being present in polynesia and SEA prior to columbus.

    So this would boot Columbus off the podium in people who discovered America.

    1. Bering strait people / native American ancestors

    2. Polynesian people

    3. Vikings, Leif Erickson

    4. Columbus


  • Id recommend disc golfing. You can start if with just a mid range disc and that’ll cost ~$15 then your good to go. Most major cities will have at least one course that’s free at a park so you don’t need to spend more after that. It has a pretty low skill floor so you can pick it up pretty easily but a very high ceiling so there is a lot to learn and grow which can help with depression. Also gets you walking outside in nature which can help with depression too. It can be as social as you want it to be, you can invite friends, or just go solo, and even if your solo you can strike up conversation with the people in front of you and sometimes they’ll even let you throw with them.
