Research traces evolution of anglerfishes' famed fishing-rod lures
The article discusses research on the evolutionary history of anglerfish lures, revealing that the original lure developed 72 million years ago and later diversified into bioluminescent and chemical-based forms. The study, conducted by researchers from the University of Kansas and St. Cloud State University, analyzed over 100 species to map how lure adaptations correlate with habitat and speciation patterns.
