Ticks did not appear suddenly with modern forests or suburban yards. These blood-feeding arachnids belong to the order Ixodida and the broader mite group Acari, with an evolutionary history reaching back at least 100 million years. Ancient mite relatives likely began the origin of ticks by shifting from scavenging to feeding on vertebrate blood. Over…
