People and 10 special things

Humans are a special animal, unlike any other species in the animal world. So, what makes people different from all species?

>>> The truth about human origin

1. The ability to speak

In humans, the throat in the throat is in a lower position than chimpanzees. This is one of the features that allows people to speak.

In fact, our larynx has lowered about 350,000 years ago with the horseshoe (horseshoe-shaped) under the tongue and not attached to any other bones in the body, allowing us to be able to Clear pronunciation when speaking.

2. Vertical posture

Humans are the only species among primates that have an upright posture when moving. This helps to free our hands which are used by many species as a tool.

The pelvis changes to be appropriate in the process of moving on the legs, combined with the infant's large brain as soon as it is still in the womb, making the human race more at risk of giving birth than the other other animals. A century ago, childbirth was the leading cause of death for women.

In addition, the curve on the back belt helps maintain balance when standing or walking, but it also makes us vulnerable to back pain and stress.

3. Little hair

People stand out from the 'brothers' in hairy primates when they are not hairy. However, the number of hair follicles on every square inch of human skin is equal (even more) than that of other species. The reason people seem more 'naked' is that our feathers are thinner, shorter and lighter than those.

4. Hands

Contrary to many people's misconceptions, humans are not the only animals with thumbs facing other fingers - something most primates can. He is the only primate that has the ability to bring his thumb all over his hand and touch the tip of his little finger, applying the little finger to the end of his thumb. The high flexibility of the hand helps us to grasp everything and perform clever manipulations with them.

5. Special brain

The largest brain in the world does not belong to humans. We don't even have big brains compared to body size. While many birds have a brain that accounts for more than 8% of their body weight, the human brain only reaches 2.5%.

However, the human brain, weighing only about 1.4 kg when fully developed, gives us extraordinary thinking and thinking abilities. What humans have done in recent decades is the most compelling evidence for this.

6. Dress up

People can be called "naked monkeys" , but most of us wear clothes. The development of clothing even affects the evolution of other species such as live lice and lice on animal bodies. But many animals are also on the verge of extinction because humans need their skin and feathers to create clothes.

7. Fire

Fire control helps our ancestors see their surroundings in the dark and ward off evil beasts. The heat of fire helps people warm in freezing weather and allows them to live in cold areas.

And of course it also helps us cook food. Some researchers argue that the discovery and use of fire has affected human evolution because cooked food is easier to chew and digest, contributing to shrinking the size of the teeth and intestines.

8. Shame

Humans are the only species shameless. Charles Darwin - the father of evolutionary theory - once called it 'the most peculiar behavior of humans compared to other animals'. The most well-accepted hypothesis is: Embarrassment helps people maintain honesty and it creates cohesion between individuals in the group as well as in the community.

9. Long childhood

People need longer parental care than other primates. According to the evolutionary law in animals, young children must grow as quickly as possible so that their parents can produce later parities. The answer to this trait may be due to the adult's brain, so it takes a long time to develop and learn.

10. Live long after no longer capable of giving birth

Most animals give birth until they die, but in humans, women can live long after they stop breeding. Many scientists for the most likely human social relations help us to win the rule of creation.
