    The next paragraph adds the explanation, why its wood is edible:

    Although most wood is indigestible to humans due to the high lignin content, the yacaratiá tree is only around 10% cellulose while the rest is mostly water with very little lignin content. Unlike most plants, cells of this tree contain large spaces within their walls which store water.

    It is in the Caricaceae (Papaya family) and apparently a pioneer species just like papaya trees. No wonder it is mostly water and hardly any lignin!

    If you search Wikipedia for plum, it is quite clear that there are various species of plants that have been domesticated and that are considered plums.

    Plums are likely to have been one of the first fruits domesticated by humans. Three of the most abundantly cultivated species are not found in the wild, only around human settlements: Prunus domestica has been traced to East European and Caucasian mountains, while Prunus salicina and Prunus simonii originated in China.

    So yes, these are different species. What the meme is referring to is probably Prunus domestica though, where Wikipedia has to say this about:

    The species’ hybrid parentage was believed to be Prunus spinosa and P. cerasifera; however, recent cytogenetic evidence seem to implicate 2×, 4×, 6× P. cerasifera as the sole wild stock from which the cultivated 6× P. domestica could have evolved.

    The other two mentioned species seem to have been species that we’ve domesticated on their own, without hybridization. At least there is no mention of it on Wikipedia.

    Wikipedia says this about P. spinosa (sloe)

    The shrub, with its long, sharp thorns, is traditionally used in Britain and other parts of northern Europe to make a cattle-proof hedge.

    The fruit is similar to a small damson or plum, suitable for preserves, but rather tart and astringent for eating fresh unless it is picked after the first few days of autumn frost. This effect can be reproduced by freezing harvested sloes.

    Since the plant is hardy, and grows in a wide range of conditions, it is used as a rootstock for many other species of plum, as well as some other fruit species.

    I’ve made some Schnaps out of sloes before, but there is not much more you can do with the fruits. Like Wikipedia says it, this species is rather used for its quality as a hedge and as a rootstock. So not sure if one would regard it as domesticated, but we certainly didn’t domesticate the fruits into being tasty.


  • Yes and it is very important to constantly remind ourselves that all our abstractions and classifications are just that. Helpful tools for us to view and understand the world. People tend to forget that and over time see their categorization as essential and natural. For example, sex and gender are both socially constructed but people forget that and then create a whole set of rules around it to reinforce that categorization including social stigmatization and infant mutilation.


  • This isn’t generally true for eukaryotes either. In plants, hybridization is a huge thing and also polyploidy. So for some groups of plants we struggle to put them in neat boxes as well.

    And zooming out to a larger view on taxonomy, plant taxonomy has seen some huge changes in the last decades with the various APG (angiosperm phylogeny group) publishings rearranging many if not most orders, families and genera of angiosperm plants.






  • Severe obesity (body weight over 200 lbs.) or severe wasting

    Wait what? I converted 200 lbs to kg and it should be equal 90 kg. This isn’t severely obese. I weigh much more and do stuff like bouldering.

    Anyways, doesn’t even matter because it is important to also train on fat bodies. Because otherwise we face the same problems medicine has with ignoring female and black bodies. Most studies have just been on white, able-bodied male bodies. To actually treat all bodies with the best care, medical professionals should be trained on all types of bodies!




  • Natural cave systems don’t have as many animals in them either, because there are just not enough nutrients around for larger populations to establish. (Exceptions are to this are caves where birds or bats nest in large colonies and there you can find huge populations of other animals feeding on the feces for example.)

    I don’t think the spiders necessarily feed on pillbugs though. At least I haven’t observed that yet. I’d think spiders would either feed on other spiders or on any flying insects getting in the garage.

    Oh and something new I’ve learned from Wikipedia about pillbugs:

    They have also been observed eating wood supports in houses, making them a house pest.

    Maybe check for that if there are so many in your garage?

    I mean, who said you have to watch it on apple’s streaming service. The pirated stream is just to clicks away anyways…

    ETA: after having watched the first few minutes of the first season, I do have to wonder why they chose to portray T. rex without feathers? This doesn’t give me much confidence in the show and I feel like many such documentaries portray nuanced and complex things in a pretty one-dimensional way, giving the viewers the feeling that the show knows for certain what it is talking about.

    Your garage is like a natural cave and there are some species adapted to live in caves, such as various species of pillbugs, spiders, millipedes, … The isopod living in garages are mostly scavengers/detritivores, meaning they mainly eat dead or dying animals falling into your garage or other organic material they can find. They basically clean up for you.
