Were does lice come from

Sadly, no one is fully sure where lice originated from. Since lice is actually a parasite, just like hookworm or certain viruses, the most logical answer is that lice has been around since the beginning of mankind. The only way to catch lice is to come in contact with one or a person who has it or has had it recently and the lice have not left fully yet. Animals cannot have lice unless they are furless or non-allergenic, meaning covered in hair instead of fur; therefore, they are a parasitic "disease" common among humans. Adult lice die within two days off of a body or without blood, and nits can only come into being with an adult louse to create it. The only explanation is that lice began with man, because the only creatures able to get it are humans and monkeys. Other animals are able to get lice as well, but their kind of lice is only interested in animals and are not attraced to humans.
