Why are humans not as hairy as chimpanzees or gorillas?

Small animals are easier to get cold than large animals, so they need fur to stay warm. The proof is that the mouse has fur but the elephant does not.

Based on the study of evolution, we know that humans also had bushy fur. However, how they dissipate is still an unexplained unknown.

Human ancestors underwent great changes of the Earth's climate. The planet is getting warmer day by day, which means that people have to travel farther and farther to find food.

Dark-neck research expert, Dr. Nina Jablonski said that having less hair helps our ancestors cool the body . This favorable mechanism makes it possible for dark people to travel longer distances, gaining more food.

The turning point of evolution was effective, which means they live longer and longer to carry out the reproductive process. Similar to us today, the offspring of their ancestors were born, inheriting their little hairy body characteristics from their parents.

All mammals (warm-blooded animals) have fur on their bodies, which helps protect their skin from sunlight and minor damage. However, each animal possesses different hair types for different reasons.

The coat is very useful for animals like kangaroo or dingo. It can help animals less detected, hiding easily from predators. Or if they are predators, the coat color supports hiding to stalk prey more effectively.

Most animals need fur to protect themselves from the sun, but some animals that live underground like moles do not need it because they have very little exposure to the sun.

Aquatic animals such as dolphins, whales, etc. have almost no fur to limit swimming difficulties.

The fur helps keep the body warm and is especially helpful in cold areas . Living in the freezing cold water near the North Pole, the sea otter is one of the warmest furry animals in the world.

Smaller animals keep less warm, which explains why smaller primates like monkeys often have thicker hairs like chimpanzees, gorillas and orangutans - the ones that are larger in size. But this does not explain why human hair is so smooth and short. Therefore, there are still many questions that scientists still cannot answer.

When hair is shed, nothing protects our skin from the sun. This leads to people starting to have darker skin because dark skin protects the body from the sun better than light skin.

Geneticist Alan Rogers estimates that the gene for dark skin only appeared more than 1 million years ago. So this may be the time when our ancestors shed their body hair.
