It think it's worth pointing out that evolution does not "experiment". It has no long term goal. Each species is evolved to function well in it's own environment. No species is an experiment that has some intention of becoming another species in the future.
Birds aren’t real!
missed opportunity for the title:
"It's Becoming Very Clear That Birds Are Not Normally"
Also that bird is the word.
I don't have any proof of this but I think it's likely that bird wings began as a mechanism for threat or sexual display. Just throwing that out there . . .
Whoa. Wild stuff.
Nice GUESSES. How about some FACTS?
What the hell am i looking at
How many tattoos and piercings does a person need in order to become a PBS presenter?
so… can we develop skin wings?
This is buffalobullcrap. Anyone believing this is a nominated educated fool.
Clicked because I thought PBS was brave enough to admit birds aren't real. Still interesting after I realized my mistake.
i would love to see a video going over what dinosaurs survived their mass extinctions. PLEASE!!!
Dragons! Are real!
Birds are not normal 😂😂😂
Nice earrings)
I always knew beautiful women weren't normal. 😂
I bet the host is an independent women who don't need no man in her life.
Hey! You got the tones right on Yiqi/翼奇!
Here be dragons.
Sorry to disappoint you, but before calling a bird a dinosaur please know that two Greek words: δεινÏŒς (deinós), which means horrible or fearful, and σαῦρος (saûros), or lizard, horrible and lizard were put together to give cold blooded lizards a name, and the result was dinosaurian or dinosaurs. A bird is not a lizard. A lizard is a cold blooded creature, a bird is a warm blooded creature. 🙂
Why is there an sponsor ad on a PBS video…?
I KNEW BIRDS WERENT REAL!
You have never watched a bat fly.
They are superior flyers.
Mammals are best flyers.
How did this person: who looks like a clown and sounds like she's a 5th grader reading a book report, get a job with PBS. She has no personality, terrible delivery, and a voice only a deaf person could appreciate.
Very interesting! Thank you.
