 #NatureGame #NorthStarGames #Evolution #Ecology #Predators #BoardGames #Science #SciComm Summary Welcome to Nature, the next evolution of Evolution! We're joined once again by Dr. Thiago Moreira to talk about this reimagining of a popular game, including covering a lot of evolutionary territory we couldn't last time. We'll talk about why everything isn't actually turning into crabs, why anteater-ification needs to be a word, how humans shape evolution from moths to elephants, what exactly a species is and where they come from, and why there's no such thing as "more evolved" creatures, (at least among anything still alive).

Jason 0:10 Today, we will be talking about nature by North Star games. Hey everyone, welcome back. This is Jason. Brian 0:18 This is Brian. Thiago 0:19 I'm Thiago Jason 0:20 again, Thiago, so y'all may remember Tiago Moreira from our episode on evolution back in season one. He is back with us today to talk about nature, which is the next evolution of evolution. So Thiago, can you give our listeners a quick refresh on who you are and what your background is? Thiago 0:38 Hi, of course. My name is Thiago Moreira, I'm a assistant professor of honors and biology at George Washington University in Washington, DC. I do have a background in zoology, and my PhD was in evolutionary biology, and my object of studies are spiders. Brian 0:54 So Tiago has the questionable honor of being our first returning guest. Jason 1:00 All right, we're going to assume that is a high honor. Thiago 1:03 I consider an honor. Jason 1:05 And Tiago, I don't know if we asked you this the first time, but we're making it a habit to ask our guests what their favorite game is. What's your favorite game? Thiago 1:13 Tabletop game? Jason 1:14 Sure. Brian 1:14 Well, I mean, it doesn't have to be. Thiago 1:17 I get into the habit of like playing tabletop games, like board games later. So like, as a gamer, my favorite was always role playing games. And I'm from Brazil, and in Brazil at the time that I was a kid, we didn't have DND officially there, so we have others. So like, I play some very old school ones, but I guess the one that marked my teenage years and young adult years more was like Vampire the Masquerade. Jason 1:43 Oh, okay, I never played that one, but I did play several other of white wolf's Orpheus is my personal favorite. Thiago 1:49 Okay, Brian 1:50 so you were sort of in the sort of 90s renaissance of indie tabletop roleplay Thiago 1:54 kind of, yeah. Jason 1:56 So did you like, have cape and fangs and all that sort of stuff? Thiago 2:01 I never do the the live action was, it's always tabletop, like, always rolling dice and like, that's it. Brian 2:07 That seems like a shame, Tiago, because I think you'd make a pretty good vampire. Thiago 2:12 I tried once. Didn't work. Brian 2:13 Okay, Jason 2:14 well, let's move on to our fun science fact. Tiago, as our guest, you get to go first. What do you have for us from the world of science. Thiago 2:21 So I got this news the other day, like and like something that is probably going to be very influential in what I do. I'm a systematic person, so I do work with systematics, trying to uncover the tree of life. And we use a lot of molecular data. And this was this news from, apparently, people in Northwestern University, they found something that actually preserves DNA better than actually what we use currently, which is ethanol. So apparently when they use EDTA, which is a food preserver, it actually preserved the DNA samples more efficiently than actually ethanol, Brian 2:57 just like a suspension, like a solution of EDTA? Thiago 3:00 Yeah, they made a kind of solution to it. And actually, they found this by accident, apparently. So they just got a sample that fell in there, like, and apparently it works. Apparently it says here that, like, they got some samples from fish in ddta, ...
