Why do zebras have stripes?
Показать описание
California State University, Long Beach biology faculty member Theodore Stankowich knows the answer to a question even evolutionary genius Charles Darwin couldn't solve—Why do zebras have stripes?
A research team that included Stankowich, examined the stripe mystery systematically in an article that appeared April 1 in the online journal Nature Communications.
Stankowich and his research colleagues, led by UC Davis' Tim Caro, found that biting flies, including horseflies and tsetse flies, are the evolutionary driver for zebra stripes, not camouflage, not heat management, not predator defense and not social interaction. Co-authors include UC Davis' Amanda Izzo, Hannah Walker and Robert C. Reiner Jr. An illustration of the Equid family tree was created by 2013 CSULB graduate Rikesh Patel.
