Oddly enough, the DNA record shows that its closest relative is the louse native to gorillas. Smithsonian clears up the remaining evolutionary mystery: the pubic louse.Īnd of course some of you out there may wonder where that intimate, third variety of louse came from. Though there is some discrepancy, we can estimate that humans began wearing clothes roughly 200,000 to 50,000 years ago. A 2010 study that performed a second DNA analysis claimed that the divergence between head and body lice actually occurred about 190,000 years ago. Homo sapiens is exploding across the planet. And they are dramatically increasing their range. They are wearing clothes-lice-filled clothes, to be sure, but clothes nonetheless. In other words, we underwent a cultural revolution. We also began drawing and carving, weaving, creating tools and burying our dead. As it turned out, the body louse branched off from the head louse about 70,000 years ago, give or take 42,000 years.Ĭlothing must have evolved at that time, too, the researchers figured. Because DNA picks up small, random mutations at a more or less constant rate, the greater the difference between the DNA of divergent but related species, the longer the separation. The last truly successful movie to come out before It was Annabelle: Creation released about a month before It the film made just over 100,000,000 far less than half of what It has made (Box Office Mojo). He measured the difference between snippets of DNA in the two louse subspecies. The first reason that can be pointed to as to why the film was so successful was the timing of its release. In 2003, a German researcher decided to put this theory to the test.

When they started wearing clothes, however, was always something of a gray area.

(Bare skin promotes sweating and is a terrific way to keep cool, ergo much of the hair had to go, evolutionarily speaking.)Īs humans started moving out of the savannah and into cooler climes, they had to start covering up. Figuring out just when body lice evolved, therefore, can give us hints as to when we became the trendy, clothes-wearing species we are today.Įarly humans were covered with ape-like hair but started showing skin some 3.3 million years ago when they took to living in hot, savannah environments. Humans have always had hair, but clothes are a more recent development. While head lice live and feed only on the scalp, body lice feed on the body’s skin but live in clothes. Cooties come in three varieties: head lice, body lice and pubic lice.
