This has been a question that many people have attempted to figure out, but scientists have figured it out.

Possibly the females are more attracted to males with more stripes or thicker stripes. But that's not why they have stripes!

Or maybe, the predators like lions or cheetahs can't see the stripes on the tall grass or from a distance. But that's not right either!

Like mosquitoes. They don't like to land on the colors black or white.

The robotic submarine searching for the flight aborted its first mission with no response when it exceeded its maximum depth limit of 15,000 feet, which is too short for the 3-D scan of the ocean floor. We are on day 40 of the search.
