Giraffes may all look identical to us. But none has exactly the same markings―and certain patterns, especially large, round patches, can boost their chances of survival before they turn 4 months old. Biologists can’t decide why giraffes evolved patches. David Lee at the Nature Institute in South Carolina and his colleagues examined 258 wild baby Masai giraffes in Tanzania for clues to the impact of patches on the animals. They found that calves with fewer, larger spots had a 17 percent higher chance of survival than those with more, smaller spots. They also found that those with more round spots had a 27 percent higher survival rate than those with elliptical* spots.* elliptical: 타원형의
