After decades of speculation, scientists believe they have discovered why giant pandas have their distinct piebald markings.
But, the reasons turn out to be anything but black and white.
Giant panda torsos have the dual-tone pattern as a sort of camouflage compromise, according to a recent paper published in Behavioral Ecology.
The white patches help the bears hide in snowy environments, while its black parts help them blend into the forest. Active throughout the year in both climates, they evolved both colors.
However, the black and white patterns on giant pandas’ heads seem to serve less of as defensive purpose, and more of an offensive one. Biologists say the contrast between the bear’s face and ears suggest its dark ears are a warning sign to predators—such is the case for carnivores with similar markings. Dark patches around their eyes help giant pandas recognize each other and can be enlarged when facing off against an adversary, Science reports.
According to the Christian Science Monitor, the study is by the same researchers who figured out zebras have their stripes to avoid biting flies—instead of evading predators, a long-held theory.
