    TIMESTAMPS FOR SPIDERS/ARACHNIDS
    1:39 -> 1:46 Several, animated (intro)
    2:54 -> 3:01 Several, illustrated (excerpt of old species descriptions)
    9:47 -> 10:08 Several, animated (dancing paradise spiders)
    10:22 -> 10:23 Several, animated (male paradise spiders with big bushy eyebrows)
    As a spider scientist (and the science consultant for CCZoo), I love these wonderful animals, but I realize that being startled by a spider can be scary (even if you like them!). An important part of overcoming arachnophobia is building positive interactions with arachnids on /your/ terms, so hopefully this helps some of y'all do so and enjoy the videos.

    As someone who is both fascinated with and knowledge about biology as well as an avid Pokémon fan, the Thought Bubble section was filled with much-appreciated Easter eggs. (Honestly, I've been trying to figure out what egg groups mean for realistic Pokémon biology for years now!)

      "Realistic Pokemon biology" is almost always a contradiction in terms.

      In pokémon biology, the evolution family more accurately classifies the species (while individual "species" are more akin to the life stages) rather than the egg group. If you really stretch it out, egg groups are somewhat like phyla (if a species could belong into two phyla, which is impossible IRL)

      One of my favorite things about grad school was learning that so many other scientists (esp those that study arthropods) are huge Pokemon nerds! While far from a perfect analogy for real biology, the idea of traveling the world and discovering new fascinating animals is what inspires many taxonomosts! (Also, yeah I've thought about that egg group question too. The best hypothesis I've had is that most of the genetic info (basically everything that makes a Pokemon the species that it is) is passed down maternally, through the DNA in the female gamete, and does not combine with paternal genetic info from the male gamete. But since males can contribute some traits to offspring, there must be a way for their genetic info to be passed down. I'd guess that things like IVs and egg moves are carried on a separate system of genetic info (like how bacteria have their main chromosome(s) and a separate plasmid) that *does* combine with that of the mom's. Finally, it seems that females are unable to induce reproduction without mating, but don't actually require genetic material from another individual to create the embryo (as seen via Ditto) which is similar to how some amphibian females still mate with males, but don't actually incorporate DNA from the males sperm into the embryo (en.m.wikipedia.org/wiki/Gynogenesis))

    I'm impressed. Thought Cafe did their Pokemon homework. Stufful can learn Baby-Doll Eyes and Flail, and can breed with Ponyta ("horses"), Wailmer ("whales"), and Mareep ("sheep").

    It's very cool to see how the question of "what is a species?" so closely maps onto "what is a language?". It feels like all the main elements are there. Common ancestry, gradual changes over a geographic area, mixing of traits, and so on. The biggest difference i guess, is that languages can "interbreed" even if they're very distantly or not at all related.

    • @SpiderdayNightLive
      @SpiderdayNightLive 3 года назад +3

      Yep! I think it's part of why so many zoologists in my generation are big Pokemon nerds

  • @happyslapsgiving5421
    @happyslapsgiving5421 3 года назад +61

    I was so convinced in the first definition, the one about making non sterile offspring.
    Now all I knew about the subject turned out to be a lie.
    Good to know.
    PS: That thing is clearly related to a red panda.

    • @SpiderdayNightLive
      @SpiderdayNightLive 3 года назад +5

      The genetic species concept is still a useful definition most of the time! The part of what you may have learned that is a "lie" is that this is THE one and only "correct" definition of species.

    And sometimes, totally unrelated species look very similar due to mimicry or convergent evolution. For example, a whale looks more like a fish than an elephant, and stick insects are not even closely related to woody plants.

  • @AlthenaLuna
    @AlthenaLuna 3 года назад +3

    When I was in high school, the "viable offspring" 'definition' was the one that was used - with no acknowledgement of any nuance or shortcomings. Some of that's on how things are taught (overly, even inaccurately, simplified until you need to relearn it with more specifics to move forward), some of that is time. I was in high school in the 90's. Domains weren't a thing being taught and used yet. When I went back to school as an undergrad in 2008, there was a new top of the tree as well as more - and more open - discussion of the nuance and limitations. I hope that's moving downward into secondary and primary schools, too.

    Species make my brain hurt. The fact that there is no real line and that they are essentially undefined and only exist in order to simplify the world is so frustrating to me, but it’s also really fascinating as well.

    Nature has no borders, only the human mind creates borders, in nature everything is interconnected, which is why it is as difficult to separate animals into "boxes", as the idea of ​​species.
    Despite this, the human mind needs the "boxes" to understand the world, so the way is to do the best possible.

      There's such a thing as realists about the Species Category. See Richard Boyd (1991, 1999) introduced the Homeostatic Property Cluster (HPC) theory as an alternative view that can accommodate the idea that species are natural kinds

    @richardwheeler6115 3 года назад

    Can you call it a definition if it doesn't accurately give the correct meaning? We aren't discussing a homophone, this is supposed to be a scientific word. So, just be truthful and say that species doesn't have a clear definition. The many definitions referred to are just, whatever that scientific group found convenient.
