Dave Rahardja<a href="https://sfba.social/tags/todayILearned" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#todayILearned</a> that whales descended from a land mammal that looks like a dog. It walked on land and swam in the water. It had hooves and webbed feet, and eyes that were set high on its skull.Its name is Pakicetus—the whale from Pakistan—because that’s where their fossils were found.This sounds like an April Fool’s joke, but it isn’t.<a href="https://sfba.social/tags/pakicetus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pakicetus</a><a href="https://www.sciencephoto.com/media/1025450/view/pakicetus-whale-ancestor-illustration" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.sciencephoto.com/media/1025450/view/pakicetus-whale-ancestor-illustration</a><a href="https://en.wikipedia.org/wiki/Pakicetus" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/Pakicetus</a>

WTLOne thing I really enjoy; discovering a word I’ve never seen before and finding its definition hits that “oh, that's cool" portion of my brain.I've been making good progress clearing up my Pocket (AKA ReadItLater) queue lately.

Jason Pettus :blobnom:<a href="https://mastodon.social/tags/TodayILearned" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TodayILearned</a> that Warner Brothers originally created the <a href="https://mastodon.social/tags/LooneyTunes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LooneyTunes</a> cartoons because they had just acquired five popular music publishers at the beginning of the Great Depression, and wanted to heavily promote the songs they now owned so to encourage the sale of sheet music. For example, the very first Looney Tunes cartoon was called "Sinkin' in the Bathtub," created specifically to promote the 1929 song "Singin' in the Bathtub."<a href="https://en.wikipedia.org/wiki/Looney_Tunes" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/Looney_Tunes</a>

Jason Pettus :blobnom:<a href="https://mastodon.social/tags/TodayILearned" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TodayILearned</a> that the oldest English-language description of card game rules was written in 1655 by John Cotgrave in his "Wit's Interpreter," and that the four games featured in the gaming section included the very first English mentions of chess and cribbage (along with a game called Ombre and another called Piquet, both once massively popular and played by millions, but now only by obscure game aficionados).<a href="https://en.wikipedia.org/wiki/John_Cotgrave" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/John_Cotgrave</a>

Jules<a href="https://social.coop/tags/TodayILearned" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TodayILearned</a> that if archaeologists are unable to fully excavate a site they will often sprinkle metal washers when putting the turf back to disappoint metal detectors and discourage them from disturbing what's left before they get funding to come back. Which makes me wonder if they can't, whether future archaeologists will stumble across these sites in 1000 years and assume washers were ways of venerating the ancient dead in our culture.
