TIMESTAMPS FOR SPIDERS/ARACHNIDS-
1: 39 -> 1: 46 Several, animated (intro)-
2: 54 -> 3: 01 Several, illustrated (excerpt of old species descriptions)-
9: 47 -> 10: 08 Several, animated (dancing paradise spiders)
10: 22 -> 10: 23 Several, animated (male paradise spiders with big bushy eyebrows)
As a spider scientist (and the science consultant for CCZoo, I love these wonderful animals, but I realize that being startled by a spider can be scary (even if you like them. An important part of overcoming arachnophobia is building positive interactions with arachnids on /your/ terms, so hopefully this helps some of y'all do so and enjoy the videos.

When I was in high school, the -viable offspring- 'definition' was the one that was used - with no acknowledgement of any nuance or shortcomings. Some of that's on how things are taught (overly, even inaccurately, simplified until you need to relearn it with more specifics to move forward, some of that is time. I was in high school in the 90's. Domains weren't a thing being taught and used yet. When I went back to school as an undergrad in 2008, there was a new top of the tree as well as more - and more open - discussion of the nuance and limitations. I hope that's moving downward into secondary and primary schools, too.

It's very cool to see how the question of -what is a species? - so closely maps onto -what is a language? -. It feels like all the main elements are there. Common ancestry, gradual changes over a geographic area, mixing of traits, and so on. The biggest difference i guess, is that languages can -interbreed- even if they're very distantly or not at all related.

Can you call it a definition if it doesn't accurately give the correct meaning? We aren't discussing a homophone, this is supposed to be a scientific word. So, just be truthful and say that species doesn't have a clear definition. The many definitions referred to are just, whatever that scientific group found convenient.

If pokemon were real, trying to figure out how they work would be a nightmare. I would love to explain how a slime monster can interbreed with a humanoid in a dress. At least you would never be bored in biology again.

Species make my brain hurt. The fact that there is no real line and that they are essentially undefined and only exist in order to simplify the world is so frustrating to me, but it-s also really fascinating as well.

I've always found it strange that dog breeds can be so physically different but are still the same species, when horses and donkeys for example aren't. Or sauropods that seem the same but slightly different sizes!

Love the pokemon reference. So many children became zoologists or biologist due to pokemon. Me included. And now, many children will become zoologist because Rae and CC Zoology. Thank you. Love you guys.

Sad there's only one more episode, such an interesting series.
They should have her do more series or voice overs. Rae has such a great voice - I'd listen to her read a User Agreement.

I'm impressed. Thought Cafe did their Pokemon homework. Stufful can learn Baby-Doll Eyes and Flail, and can breed with Ponyta (-horses-, Wailmer (-whales-, and Mareep (-sheep-.
