  • The single, simple answer is the one that you don’t want to hear: There is no clean split. Bats are a large and diverse group of flying mammals just like birds are a large and diverse group of flying dinosaurs.

    The simplest answer I can come up with (because it’s actually a very complicated and convoluted topic that I wouldn’t truly do just anyway) is: Most birds can fly because they are an offshoot of one group of dinosaurs (avian dinosaurs) that survived the last great extinction when their non-flying non-avian dinosaur relatives did not. Basically the ones that couldn’t fly mostly went extinct. And mammals mostly don’t fly, which is possibly because several groups of vertebrates beat them to it and essentially filled all the niches that would have been available to flying animals, kind of blocking that path for them.

    Obviously that’s nowhere near the full story. There are lots of other factors at play, like some of the peculiarities of mammalian and dinosaur physiology that made one group better suited to flight than the other, ramifications of the great extinction that killed non-avian dinosaurs as well as most large animals in general and whole swaths of other species, and so on.


  • I don’t think of it in that mind frame, to be honest.

    To me it’s our bodies that have evolved a general reaction to foreign proteins / materials with an inflammatory response (which can feel itchy), though that’s obviously the watered down way of thinking about it that doesn’t really capture the full picture.

    Often times I don’t even know there’s a mosquito on me unless I happen to see it. Some species are just super tiny and don’t seem to cause any pain when they feed. Others are so large that they “itch” (i.e. you can feel their presence) just from them landing on you, whether they have time to bite or not. Either way, it’s not the pain or itchiness that motivate me to keep their populations under control, it’s primarily concerns over the spread of disease.

    For most species of mosquito, humans aren’t really their primary target nor are humans the main source of food for them. And, it’s only been in very recent history that humanity has had any ability to control mosquito populations on a large scale, not even a blip on the evolutionary scale. So give it time, maybe those of us who don’t get itchy from mosquito bites are the fittest amongst us from an evolutionary standpoint and eventually those genes that lead to itchy reactions will go extinct. But I don’t think that there’s any significant evolutionary pressure on mosquitos as a result of how itchy or not itchy their bites are.


  • I’ve never heard of that one specifically and could find no sources mentioning it online. So, I’m being up front when I say I do not know the specific answer.

    Having said that, sometimes if we’re building out scenarios in our minds based on an inaccurate or flawed premise, that can also lead to flawed outcome in our logic. For instance, is it actually truly possible to get a 430 on any family member that you want … like just because? And if so, is it possible there are other extenuating circumstances that you might not be considering (ex: Trump is not a family member, none of your family members are president of the United States, etc) which could explain why things might lead to a different outcome between your family member(s) and Trump?

    Having said that and given the additional context you provided (i.e. Mental Examination), I’m wondering if it’s a situation where the individual needs to be more of an immediate threat to the health / life of themselves or others before it’s applicable? Even if you did try to make that case (because I know at least some people would), it’s likely not a case where any random person can just make an accusation / report against a well-known public figure to whom they have no clear social ties and expect it to be taken seriously.

    Also, this wouldn’t apply to the president of the USA, but even people who legitimately do need some kind of immediate institutionalization often can’t get it when they need it. It would be an understatement to say that the mental health facilities in this country are overwhelmed and underfunded.

    I’m not an entemolo intenolo bug scientician and I know nothing of the specifics of this species, so I can’t weigh in there.

    However, sometimes these new species have literally been right in front of our faces the whole time, it’s just that they’re barely distinguishable from other very similar and more common relatives.

    This is, of course, a vast oversimplification of things, but I remember reading an article about a new beetle being discovered in some random suburb. Essentially the reason the new species was discovered is because someone was counting the number of hairs on the larval beetles’ butts and noticed the discrepancy between two different populations and then realized that they were dealing with two different species, one of which had not been previously described.

    I’m not ADHD, but that particular passage using that particular font and those particular colors seemed to speed up my ability to read the text. But when Staments posted below (https://lemmy.zip/post/45655234/20636698) using what looks like the same methodology, it ended up being an impediment. I struggled to even get through the first sentence.

    So I have to wonder if there’s more to it than just randomly putting a character or few in bold at the start of each word – like maybe it’s also highly dependent on things like the font being use and making sure to use specific words and phrases that are conducive to this technique.




  • Since this is Science Memes, I’m feeling emboldened to geek out a bit.

    In my part of North America, there are a lot of pollinators besides bees “sexing up” the apple trees. I’m guessing it’s that way in many other parts of the world, too.

    On the coolest days, you might not see any bees at all, but the flower flies (aka hover flies) will still go for it. On the warmest days, bees may even be in the minority of pollinators. I see all kinds of different fly species, a multitude of different wasps, many types of beetles, and sometimes even moths and butterflies – weather depending. Plus, even that time of year, there are often other bee species which are active besides just the invasive non-native honey bees.



  • I’ll believe it when I actually see it.

    I don’t know much / anything about the particular crowd being referenced in that meme.

    What I do know is my conservative neighbors, conservative family, and so on. These people legitimately and without any shame or self reflection believe that because they did not get “free healthcare” nobody else deserves it. They are unwavering in the belief that they should not have to pay for other people’s medical bills. They truly think that anybody getting government healthcare (aside from retirees) is a leach on society and that they cannot afford to keep paying for those people.

    I know this because I have conservative neighbors, conservative family members, and so on. And they aren’t the least bit afraid to air their opinion on this any chance they get. Now I don’t live in Nebraska USA, but I honestly have a hard time believing that conservatives in the midwest are all that different from conservatives on the east coast.


  • Not to get too serious, given the topic and the community I’m in, but…

    There’s a saying along the lines of “You can’t reason someone out of a position they did not reason themselves into.” And the overwhelming majority of the time, it’s completely true.

    Ridiculous as it sounds, there are large numbers of people out there who believe that being gay is a choice. These people legitimately feel like any recognition and representation of homosexuality risks turning people gay.

    You can spend all the time you want asking them when they chose to be straight and logically explaining things to them, it almost certainly will not matter.


  • I see this from two different perspectives:

    1. There are some ingredients I just don’t like the taste of. But, in some recipes and if prepared properly, I’m fine with them. Green beans are an example. I don’t like them. But creamy green bean casseroles are fine and vegetable soup with green beans is totally acceptable.

    2. Then there are things like desserts that I’m picky about because if I’m going to screw up my metabolism and caloric intake for the day, it better damn well be worth it. I’m not going to waste my time on a substandard sugar and/or fat filled treat. I’m going to skip on that dry cake, jello salad, faux ice cream, fake chocolate sludge, etc.



  • Almost literally, the moment Trump was sworn in as president, the same exact folks who spent the prior 8 months of their lives blaming Biden for the high cost of eggs suddenly had an epiphany that the president does not directly control the price of eggs. And then when the president DID specifically and directly affect the price of groceries as a result of tariffs, those same people suddenly insist that grocery prices are based on complex and rapidly changing global socioeconomic phenomenon that cannot be predicted nor controlled and besides this is still Biden’s economy because it was so broken that Trump hasn’t been able to fix it yet (even though he promised to have it all sorted out in a timeline of days).

    They live in a separate reality, void of fact and logic, and I honestly have not figured out a way to reason with that. As wiser folks have said much more eloquently than I could, you cannot reason people out of something they did not reason themselves into.



  • How do you know if someone owns a Steam Deck? Don’t worry, they’ll tell you.

    So anyway, a couple years ago I bought a Steam Deck. And since I bought it, virtually all of my gaming is on the Deck. Prior to that, virtually all of my game time was on a Windows PC. So, for me personally, there’s been a big shift towards Linux for gaming.

    The other big change that’s coming for a lot of people I know: end of Windows 10 support. Honestly, the majority of people I know who still have a traditional Windows PC are using machines that can’t be upgraded to Windows 11. These computers are perfectly functional and do everything the users need them to do, and they have no inclination to go out and buy a new computer just because. Especially in this economy. Additionally, there are quite a few people with computers that are capable of running Windows 11, but they have no desire to upgrade to a worse experience and an experience that is randomly different in a myriad different ways for no good reason. Both groups are ripe for the picking in terms of a switch to Linux. No, the year of the Linux desktop is not here, but the conditions for such a change are building. And this Steam data may present a picture of the larger trend. Who knows?


  • Same here, I’m in the Southeastern USA. Monarchs are one of those species I pay attention to, and this spring we had a bumper crop around here. I’ve never seen so many of the caterpillars and adults in the past 10 years or so I’ve made an effort to look.

    Granted, that’s also true for the handful of other butterfly and moth species I keep tabs on, they’re all having a really good year this year it seems. Luna moths, several different swallowtail species, Gulf fritillary, regal moths, hummingbird butterflies. About the only thing that I’ve seen less of this year are the giant hummingbird hawk moths.

    But these things do tend to ebb and flow. One year certain “bugs” are everywhere, the next year they’re hardly seen. And with the monarch lifecycle being what it is, one good year like this one, even if it’s good in more than one region, isn’t a guarantee of long term success.
