Did anyone else notice the slight pencil marks under the 'my name is. ' card at the end? I thought that was nice like even though these people possess mass amounts of knowledge unknown to the slightness of a teenage mind such as my own, they also possess idiosyncrasies that make them ever more human again. lol.

Hey Crash Course! Hope this is still active.
Er. Among your many names, you mentioned -sarcoterygiian- and -osteichtyian-, if I'm not mistaken. The sarcoterygiians are FISH, as well as the osteichtyes. Why then are you using that to qualify a human being?

i would love to know, how the uterus evolved. i mean, from hard-shelled egg outside the body to semi-parasitic growing inside the mum. evolving yolk to a placenta. this seems like such a crazy step.

I was just reading the DNA of tunicates is more similar tot he DNA of
other chordates, even though lancelets are closer to fish in morphology
& lifestyle. How do we explain that?

you're not an American teenager if you've never been staring at the wall in your dark room at midnight while the crashcourse theme plays at double speed for the ninth time that night

Been learning about this recently, to add to the Hollow Dorsal nerve cord, post anal tail, notocord and pharyngeal slits. Also the endostyle, a precursor to the encrocine system.

It wasn't mentioned in the video that reptiles have 3 chambered hearts except the crocodile which has a 4 chambered heart.

Just think what would happen if the fisherman didn't realize it is a fish known to be extinct. simply carried it home. cooked and eat it?
