Gene research on lice suggests that humans started wearing it 70 thousand years ago, US scientists said. clothes At that time, mankind began to move out of Africa to settle in Europe with cooler climate.

Scientists say that lice provide a unique research perspective for the evolution of human clothing. Only human beings carry this special parasite, lice can lay eggs on clothing and transmit typhoid and other pathogens. Mark Stoning, a molecular anthropologist, said on Monday: "it seems obvious that when people start wearing clothes frequently, the louse also comes into being."

 
Stone rather saw his son after a homework and thought of a study of mankind. clothing The earliest way to emerge. He said, "the teacher's note is mainly to tell parents that students found lice on their heads. Because humans can only spread louse from other people, they can not be transmitted from animals such as cats or dogs, and lice can not survive 24 hours after leaving the body. So I thought that the transmission of louse can always be human centered.

Most experts have already recognized that human lice are derivatives of lice on the head, and that the louse can be derived from humans when they start wearing clothes. Stone and other people studied the DNA in the human louse cells, and the date of their occurrence was traced back to about 70 thousand years ago.

 
Stone said the figures are consistent with more and more evidence that modern humans originated in Africa and migrated to Europe about 100 thousand years ago.
