A team of researchers from The University of Texas at El Paso uncovered new evidence explaining why the rattlesnake’s rattle, one of nature’s most iconic warning signals, has persisted and remained effective over millions of years. The team engineered a lifelike, 3D-printed robotic rattlesnake to test how 38 species at the El Paso Zoo responded to rattling behavior.
