When modern humans began migrating out of Africa, unwittingly also carrying lice. This can be traced from the nature of genetic similarity of hair lice are found in various parts of the world today with ancient human head lice.
For example, body lice in the hair found 1000 year old mummy from Peru. Genetic code of organisms that are small it can be said to be the same kind of fleas that are currently living in Africa, Europe, and Asia.
"This tells us that this genetic type spread worldwide the same time people also spread and migrated around the world," said David Reed of the University of Florida. As written in the Journal of Infectious Diseases, Reed and colleagues noted three groups of head lice, A, B, and C.
Group A is found in all parts of the world, group B only in North America and Europe. Meanwhile, group C included the most rare. Group B previously grown apart in America, but the explorers took it to the European continent, as well as group A from Europe to America.
Researchers accidentally discovered head lice on the heads of type A mummy found in the region bergurun on the southern coast of Peru. Researchers found more than 900 head lice from two mummified head from the Tiwanaku culture Chiribaya it.
"There are very many. This is shocking. It's really worth because of how many lice in the hair," said Reed. He surmised, braided hair combed so rarely be paradise hair lice.
Having studied his DNA code, it enters the flea A. This shows the lice out of Africa and spread first in the Americas before the Europeans.
Lice from group A closely with body lice often called blood-sucking bastards. Lice that live only in the human body is known to spread disease-causing bacteria, mialnya thypus.
Reed believes some lice from mummies also carry the bacteria. With memeplajari bacteria, the history of human migration may also be traced. Bahakn, including the history of the spread of diseases such as thypus
