This suggests zebras don’t have true camouflage. This doesn’t help explain why zebras can survive against lions. We still know zebras’ stripes stand out against the background.

This suggests zebras can identify which lions are preparing to hunt. But it doesn’t suggest zebras can escape from those lions or can somehow hide from those lions. We still know zebras’ stripes stand out against the background. How can they survive being preyed on by lions?

This tells us a feature of lions that makes them better at hunting. But if we’re trying to explain how zebras survive, we want an answer that makes lions worse at hunting zebras.

This tells us what lions do with food after killing prey. But we want to know why zebras don’t become dead prey in the first place.

This tells us something about zebras’ stripes that can help them avoid being killed by predators. If the stripes can make it harder for a predator to see the outline of an individual zebra, that predator might have a more difficult time killing that zebra.
