In the middle ages, humans couldn't get away from lice. They were an unavoidable part of their life and lice didn't discriminate; they infected all parts of society from serfs to royals. People in the Middle Ages took lice to their grave as well. They lived a life of itch, itch, itch!
The most likely explanation is that by the time H. sapiens evolved in Africa about 200,000 years ago we had our own lineage of head lice, and then picked up more from H. erectus on our travels, says Reed. The study is reported in the current issue of PLoS Biology1.
“We've discovered the 'smoking louse' that reveals direct contact between two early species of humans,” probably in Asia about 25,000 to 30,000 years ago, says study leader Dale Clayton, a professor of biology at the University of Utah. “Kids today have head lice that evolved on two species of cavemen.
As Aaron struck the dust with his staff, a stream of bugs, believed to be either lice or gnats, swarmed across Egypt. The people of Egypt were tormented with these bugs, completely unable to escape them, no matter where they went. Still, the Pharaoh refused to let the Israelites go.
It also appears that Romans regularly used delousing combs to rid themselves of lice and fleas, Mitchell said.
When Victorians were infested with head lice they would visit the local bathhouse to receive an arsenic and quicklime treatment. During this treatment the different chemicals would burn off the hair weather it is on their head or the entire body.
The First Humans
One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
The analysis suggested that the two parted ways somewhere between 30,000 and 110,000 years ago, which gives us an idea of when our ancestors started wearing clothing. Head and clothing lice are closely related and share an ancestory with chimpanzee lice, which makes sense, since chimps are our closest relatives.
Although there is a very slight possibility that you could get lice from an inanimate object, such as a brush or a pillow case, almost all cases of head lice occur through direct head to head contact with someone who is infested. The longer answer goes back over 800,000 years.
Fortunately for the lice population, if not for their hosts, conditions of trench warfare proved ideal for their rapid spread. Of the three types of lice - head, pubic and body - the latter was far and away the most common. Lice could only thrive in warm conditions - which was provided by body heat and clothing.
So worms were treated using bitter, purgative plants such as wormwood or gentian, which would both kill the worms and expel them by provoking a nasty bout of diarrhoea.
Head lice and eggs have been found on the hair of Egyptian mummies. Nine-thousand-year-old louse eggs were found in hair samples from an individual who lived in a cave near the Dead Sea in Israel, while large numbers of lice were recovered from a 3,800-year-old female mummy from the Loulan period.
Head lice are annoying, but they're not dangerous and they don't spread disease. They're not a sign of poor hygiene — head lice need blood and they don't care whether it's from someone who's clean or dirty. It's best to treat head lice right away to prevent them from spreading.
Genetic work on living lice had suggested they arose during the time of feathered dinosaurs, but fossil lice are few and far between. The tiny creatures are unlikely to fossilize, and even if they do they're hard to spot.
The molecular divergence of body lice from human head lice dates back to some 170,000 years ago when modern humans started wearing clothing and lice found themselves a suitable alternative niche to start diverging. Development of clothing, therefore, may have been an essential factor in the expansion of modern humans ...
One is found worldwide and evolved on the ancestors of our species, Homo sapiens. The second type is found only in the Americas and evolved on Homo erectus, another early human species, but jumped to Homo sapiens about 25,000 years ago.
Human lice likely co-evolved with people. Our primate relatives harbor their own species of lice. Recent evidence is suggestive that body (clothing) lice evolved from head lice.
Jeanne Calment set the absolute record for long life. She died when she was 122, in 1997. Since then, no one has lived any longer.
The closest living relative of the human louse Pediculus humanus is found on chimpanzees. Like chimpanzees and humans, these lice shared a common ancestor about 6 million years ago, and the head lice that live on humans today have been with us for a long time.
The British also developed a combination of naphthalene, creosote, and iodoform made into a paste which could be applied to the seams of uniforms with a good result of eliminating lice in just a few hours.
'46 The Army also established divisional baths to turn lice-ridden men into clean soldiers, with the aim being to wash every man at least once every 2 weeks.
Head lice (Pediculus Capitis) are a common problem that most parents, students and teachers in Australia are familiar with. They are tiny parasites, about the size of a sesame seed, and live on the human scalp and hair. They feed on human blood up to 4 times a day.
