Why are some animals black and white?

The evolutionary purpose of black and white coloration in animals varies significantly across species, serving functions from pest deterrence to survival camouflage. Research by zoologist Dr. Martin Howe demonstrates that zebra stripes create optical illusions that confuse biting flies, effectively discouraging them from landing. In contrast, Professor Tim Carrow explains that the giant panda’s high-contrast coat provides essential camouflage in snowy, rocky mountain habitats, making them nearly invisible to predators from a distance. While some animals like skunks use these bold patterns as aposematism—a warning signal of toxicity or danger—researcher Hannah Rowland suggests there is no singular explanation for these traits. Instead, animal coloration results from a complex mixture of environmental pressures and biological needs. This multifaceted nature of evolutionary biology confirms that the reasons behind such distinctive patterns are rarely simple or uniform across the animal kingdom.
