"It was a revelation to think that the pests that live in our beds today evolved more than 100 million years ago and were walking the earth alongside dinosaurs," said researcher Mike Siva-Jothy. "It demonstrates that the evolution of bed bugs is far more complex than we previously thought."

If the Bible contains the earliest reference to the passport, the origin of the two French words 'passer' + 'port' meaning "to pass through a port" dates from the 15th century. It was also written as a compound word at the time, "passport."
