Why the hot peppers?

What of the fiery pepper is actually a trick of evolution is used to stop animals eating the fruits and seeds of our destruction.





But the smart replacement, creator still leaving the birds, which "province butter" before the heat, the fruit can be hard to swallow food and traditional breeds of chili to go further.

This helps ensure the survival of their house chili. A team from the University of Montana and the University of North Arozina (U.S.) substance found in chili peppers is capsaicin, making it especially spicy hot. This substance stimulates the skin and tongue, which is feeling the heat and pain, to fool the brain that it is "burned" skin. Capsaicin caused animals to run away but the bird unharmed.

While exploring the eating habits of animals living around the region have grown peppers in southern Arizona, we saw the mouse and the desert rodents did not affect the fruit but delicious cup of fruit other. Meanwhile, the birds almost exclusively to chili.

This finding could open new ways for effective control of harmful birds to plants, seeds or invent something special to kill the pests without affecting the birds.
