Mini Wing Tutorial

I've been saying dinosaurs and birds belong to the same group since I was 7 or 8 years old (I'm 63 now).
My parents just used to chuckle quietly and say, "yes,Erwin.."
Finally, the rest of the world has caught up (so to speak).
But then, of course, some have to get carried away and put feathers on Sauropods and every other dinosaur order.
Some people just don't appear to understand when you say, "All mosquitoes are insects; but that doesn't mean that all insects are mosquitoes.".
Nice, clear diagram (I used to be a high school science teacher & some of the crappy posters or diagrams in the students' textbooks were just garbage. I often created my own for my classroom and often had other science teachers ask me where I purchased my posters... lol).
