Where did the rat flea originate?

Fleas are blood sucking parasites. They have the potential of spreading dangerous diseases to humans and other animals. It is possible the first flea was native to Africa and traveled by boat on the back of a rat to different destinations around the world. Even though there are many different types of fleas, they all have similar body parts; eyes and legs help them survive the dangers of their life. A flea undergoes four different life cycles to become an adult. The Black Death, also known as the Bubonic Plague, is one of the deadly diseases that the flea can spread to man and animals.
