    Everyone who eats avocados owes a debt of gratitude to ancient giant sloths. They were big enough to eat the avocados whole, stone and all. Then the stone passed through their digestive system until it was deposited with a helpful amount of manure. Thus giant sloths spread avocados around and allowed them to grow and flourish.

    As a Costa Rican tour guide I ask that you take a moment to help us shed light on a serious issue occurring here: in La Fortuna of San Carlos (very popular tourist location) some private land owners are setting up “Sloth parks” where they are forcibly taking sloths from their place in the wild so that they can put them in their “park”. We have contacted the authorities but very little is being done as evidence is difficult to come by (there are rumors that homeless or drug-addicted citizens are paid to turn in the sloths in bags, but the declining populations of sloths in the wild make it clear that rumor or not, *something* is going on as they have disappeared far too quickly for it to be caused by natural selection, etc.) There is even a video of our current president with an “expert” saying that there is no evidence that these parks are doing anything illegal, but it is clear to the local guides as it is unnatural for a group of sloths to all reside in one small location (and mysteriously, all of the sloths typically found in the area have almost completely disappeared, when we would often see at least one, two, or three per day along the forest edge by the road). Please help by posting and spreading the word on social media or whatever you use, we want to put pressure on the government to take this issue seriously before it drastically affects the sloth population.

Like i m fascinated by science, extending way outside my field, so i have a pretty good level in some fields like psychology and biology, i'm actually taking courses on that last one for my future (wanna specialise in astrobiology) so i have a hard time finding long form, deep dive content that isn't limited to the pop cullture view of biology, or isn't a full on lesson or documentary.

      Primero quiero comenzar mencionando que estoy de acuerdo con usted, me hubiera gustado ver nuestros científicos mencionados en este vídeo ya que nosotros que trabajamos en el sector nos esforzamos mucho por la flora y la fauna que tanto amamos.
      Segundo, si creo que hay una manera de decir las cosas y también pienso que es importante reconocer la contribución que hacen los países extranjeros para lo que es la investigación de nuestra biodiversidad. Creo que para nadie es un secreto que una gran porción de voluntariados y expertos no son Ticos (pero recalcó que nosotros también tenemos expertos realmente increíbles que no suelen obtener el reconocimiento que se merecen). Aun así, mucho del dinero también viene del extranjero, en especial el estadounidense nos da una gran contribución a la economía. Siento que es importante agradecer cada vez que nuestro pequeño país se menciona en algo que nos puede dar más atención, y como resultado más movimiento en el turismo, ya que esto nos ayuda obtener más fondos para investigaciones. Creo que este canal es uno de esos, porque aunque la mención de nuestro país fue breve el canal es grande y ellos se esfuerzan mucho en siempre dar material de alta calidad.
      Amigo, estoy de acuerdo contigo pero no nos enojemos - esto no nos ayuda obtener lo que queremos. Nos representas en cada comentario, y no quiero que parezcamos como un país enojón o malagradecido.

    Actually, understanding through experience, the modern paradigm of fitness versus physics a sloth makes a whole lot of evolutionary sense. At one point I knew that I had to strengthen my core, or the weight of my upper body would cause permanent damage to my spine especially due to the nature of my work and my age. Naturally, for several months I approached this problem by doing several sit-ups and squats every morning. My back gave out anyway and I didn't even get a 2 pac out of it all. It turns out that physics has an interesting solution to this. One of the best ways to achieve lasting and showing core strength is actually the plank and reverse plank positions using a yoga mat. It turns out that sit-ups can actually cause spinal damage. It's been 2 years since I learned that, and I feel and look great. I'm 36.

      Yeah- there is a school of thought that the main job of core musculature is to keep the core rigid during under load, and strengthening exercises should reinforce that

    I'd still argue the adaptions of the sloths are not great, simply due to how un-adaptable their lifestyle is to any environmental changes.
    Also I had always assumed that their ease of hanging from branches wasn't really about muscles, but rather passive, hook-like arms.
    Interesting information and great documentary.

      We could argue this is tendentially natural for young people. This would also explain the outrage when World of Warcraft introduced Mists of Pandaria and they were constantly told to slow down. But such an important teaching as contrast, addressing the right audience. When a team activity results in a 'wipe' because people were hurrying too much and then took time getting back to action, I always tell people that slower is quicker. I might also refer to the pro-level discipline of consistency racing where the aim is not to minimize your lap times but to have steady ones so that resource consumption can be planned properly and you're not burning through them. - This is what is also described by the saying "Slow and steady wins the race". - Finally, this is also game theory. If two racers at the head are battling each other fiercely, that burns up lots of resources and might cause mistakes, and racers behind them can benefit from that if they 'prey' on the right moment to exploit.

    You could honestly see it in this way as well: these types of animals(slow and not showy) are not running away from anything.
    You can see how cheetahs and eagles and running from another predator or hunger and to catch their prey, but sloths and snails have a home or can easily protect themselves from other predators and they can easily get their own food or sustenance easily as well.

    Two-Toed Sloths (genus Choloepus) and Three-Toed Sloths (genus Bradypus) are the sole living genera of the families Choloepodidae and Bradypodidae respectively, despite the superficial similarities, these two monotypic families are not closely related at all, the former is the sole extant family of the superfamily Mylodontoidea, which more closely relates two-toed sloths to the darwin's ground sloth (Mylodon darwini), while the latter is the sole extant family of the superfamily Megatherioidea, which more closely relates three-toed sloths to both the cuvier's colossal ground sloth (Megatherium americanum) and the jefferson's ground sloth (Megalonyx jeffersonii).

    • @krista2216
      @krista2216 Год назад

      Not closely related?! Interesting. This tells me that we know very little about the pressures of evolution. Eyes, teeth, etc, these are easy to understand why they have developed several separate times. But the fact that convergent evolution created the sloth more than once is very interesting! We give very little respect to these animals...

    Next time you attempt the "Hang for 100 seconds Carnival Gimmick" make sure to put your thumb under your gripping fingers and not above! It creates a wedge that allows you to hang for much longer due to mechanical advantage. I have won $100 for 100 seconds at this gimmick using this technique. I also rock climb but can't do the 100 if I use a traditional "thumb over fingers" grip. Good luck!
