This animal is ten thousand times more spicy than humans, but its secret is ... unfair!

He ate chili like . ate vegetables but didn't feel any spicy 'sniffing'!

In the world, in addition to humans, there is only one other mammal species that has a "hobby" to eat spicy. That's "Chinese tree shrew" , temporarily translating "Chinese tree shrew ".

However, it does not belong to rodents but belongs to many teeth - scandentia. This is a small collection of about 20 mammals, living in tropical forests in China and Southeast Asia.

Chinese tree shrew.

In fact, science has long discovered that tree shrews have close relatives with primates, and love to find spicy food in their natural environment. But the reason why, the recent study of the Chinese Academy of Sciences revealed.

Scientists here captured 5 tree shrews and 6 mice from the wild environment. They then feed on pepper leaves (Piper boehmeriaefolium) - a capsaicin-rich plant is also found on peppers.

As a result, mice are constantly licking the parts exposed to capsaicin of pepper leaves, and the tree mouse is "awake".

Next, based on observing the tree shrew brain under a microscope, the researchers found this species mutated the gene at TRPV1.

This is a receptor attached to the ion channel, located in the tongue and throat of mammals.

This part will feel pain, numbness (when eating spicy for example) and then report to the brain, creating vigilance for food sources.

Tree shrews can eat pepper, chili, . as much as you want, far beyond humans.

However, due to the mutation of TRPV1, Chinese shrews no longer feel numb, pain when eating spicy.

And of course they can eat pepper, chili, . as much as you like, far beyond our people.

But in nature, there are many other plants that contain chemicals that cause sharp throats when ingested, in order not to be "re- eaten" by animals .

However, in the case of Chinese shrews, they have developed the ability to eat "super-grade" to easily find more food sources. The fruit is "thick tangerine shell with pointed nails" right?

In addition, we can affirm: know how to enjoy spicy taste only in humans. Spicy food is always numb but . very refreshing, suitable for a cold rainy day!
