    Fun fact worth noting: humans and octopodes split back when our shared bodyplan was effectively a worm who just got legs. Octopuses have been shown to be able to learn and memorize letters, patterns, their different keepers (e.g., spitting at one particular keeper they didn’t like), etc., and all the intelligence they’ve been demonstrated to learn evolved separately from humans.

    So we’ve actually got two examples of “worm with newly-evolved legs” becoming pretty damn smart on Earth, not just one - which makes my bet more on the “if the biosphere got to worms with legs, there’s a lot of smart stuff there”

    There is no moral way to raise a cat.

    Either they live inside and live an entire life in a few thousand square feet at best for 16-20 years, or you let them outside to hunt and they kill tons of wildlife and are exposed to becoming roadkill/coyote food etc.

    My personal dodge is to adopt old cats that have already been indoctrinated into inside life and who could never be let out anyway.













  • Invertebrates? No. All out

    I invite you to meet the awesome jumping spider, whose eyes are very especially needed set up to be forward-facing for depth perception for their jumps, and who hunt other spiders, as well as the wolf spider, who are also a hunting (as opposed to web) spider.

    In fact, you can use the chart of spider eye layouts to pretty much identify whether you’re looking at a spider who builds webs and waits or a spider who hunts:

    Anyone with two big forward-facing eyes is probably looking around for their next meal; the rest are building a web, trapdoor, or taking some other approach.
