They improve the detection ability while setting obstacles for parasites. These body hairs prolong the search time of parasites, which makes it easier to find parasites, because it takes more time for these worms to climb over the body hairs. The above results were obtained by Yue Se and his colleague Isabel Dean through experiments.
New findings:
Body hair can help find parasites and even prevent insect bites. A study published in the Biological Newsletter of the Royal Society helps to explain why humans have less body hair than other apes wearing fur coats, but still have the same hair follicle density as chimpanzees or gorillas of the same size.
Slender body hair consists of "hair" and "end". The former is the peach fluff mentioned above, while the latter involves the hair and pubic hair growing around the armpit and genitals. Michael Swa Yue Se, a professor of animal and plant science at the University of Sheffield in the UK, said: "All these body hairs are connected with nerves, which can help us find the movement of hair.
