Why did penguin stop flying?

Penguins' swimming prowess cost them their ability to fly, a new study says. Penguins lost the ability to fly eons ago, and scientists may have finally figured out why.

Birds are unlikely to fly in jet streams because jet streams have high wind speeds of 250 mph, which can throw birds off course to their deaths. Additionally, most birds only fly below 500 feet; only a select few high-flying birds can barely reach the height of jet streams at 30,000 – 52,000 feet.
