We all have to evolve ~ ~ ~ ~ E

11 human illnesses were singled out ~ ~ human evolution is not perfect ~ ~ now hope to contribute to the evolution of mankind, huh ~ ~ ~



; 1. his head while on the death of brain cells in hypoxia
head structure is not suitable for high-speed vehicles, aircraft and high-speed operation of amusement park toys dangling. In addition, once the lack of oxygen, brain cells does not take long for death. The epaulette shark brain even if the oxygen for one hour, may still be the life of mind.

2. easy to damage the ear canal is difficult regeneration of hair cells in the human ear canal

on auditory hair cells is critical, but these cells are also easily damaged by loud sounds, which damage hearing. If we have ears like a bird, the bird will automatically regenerated hair cells.

3. teeth and mouth, choking on the teeth by eating too many old

reason why we are choking because the mouth is also the entrance of food and air.

grow in front of a security if the tube is like a filter, it can block the food, while keeping the air moving. Humans have 20 teeth enough, basically useless wisdom teeth but still

4.

too narrow view of human eyes to see anything, we need the middle of the light through the retina a small place, which led to the vision of human beings than other animals is narrow. If there is a broader human retinal photoreceptors receiving surface, not only to enhance night vision, more to see while playing multi-angle flying football.

5. Also, hidden behind too much too long neck

the human nervous system and neck injuries are the most vulnerable part, has chosen a very important possession of the nervous system, once the subject of these important neural loss, we will break down. So then the neck should in fact have evolved shorter, of course not the best neck, but it was like a gorilla.

6. heart

not self-healing capabilities of human liver can repair itself, but the heart can not. Let the heart with liver regeneration would be a major medical breakthrough. In addition, the heart also need a new vessel, that is, the growth of blood vessels can be automatically available from the embolization at the bypass, continue to play an oxygen function.

7. elbow

a length of the exposed nerve a few centimeters to a length near the elbow nerve, is the result of human evolution, but it is left exposed, without adequate protection, it is vulnerable to injury. If it grows inside of your elbow, this problem does not exist.

8. inflammation of the appendix is ​​useless old

appendix also what to use, it has not clear, but once it is inflammatory, but extremely painful, and even endanger your life.

9. genitals testicles can evolve into the body like a male's testicles

10. knee cartilage repair

knee wear hard all his life under enormous pressure, cartilage subjected to wear, difficult to repair itself. Spring in the other amazing animals, thanks to their perfect legs structure, can greatly reduce the energy for running.

11. foot

lack of shock absorption structure of our lack of shock-absorbing function of the foot, caused by the impact of walking will be directly transmitted to the knees and hips. If the length of the foot and then a layer of fat or collagen, our body even more perfect.
