This week we have a TPL Kids visitor who wonders why penguins don't fly.
It might be a surprise, but long-ago penguins did have the ability to fly.
What happened?
According to research highlighted in National Geographic, scientists believe that penguins evolved from an auk-like ancestor. Their wings reduced in size which made flying more difficult so eventually they adapted.
So, the next time you see penguins waddling about, consider that in another time these majestic birds soared high above.
