Bedbugs evolved 100 mn years ago during dinosaur era: Study

A study by international scientists has revealed bedbugs evolved over 100 million years ago, walking the Earth at the same time as dinosaurs like Tyrannosaurus rex. The study is based on bedbugs collected from wild sites and museums around the world over a 15-year period. "It shows evolutionary history of bedbugs is far complex than previously thought," researchers said.
