How can a person become toxic?
Not only humans but all mammals have the potential to produce poison. "Basically, we have all the ingredients to make toxins," says Agnish Barwa, a scientist and researcher at the University of Okinawa in Japan. That is why all the animals that have the ability to make saliva also have the ability to make poison and due to climate change man can create the ability to make poison.
Similarities between snakes and humans
Scientists examined the DNA of a venomous snake called "Habo" and concluded that the genes that produce saliva are the same in snakes and humans. However, human saliva helps digest food. Humans and snake saliva produce a protein called "Kelly Crane" and it helps to dissolve the proteins in the food. According to evolutionary theory, the ancestors of humans and snakes were the same millions of years ago. Therefore, the system of saliva production in them was the same. However, due to climate change, the saliva of snakes and poisonous animals became poisonous, but the basic machinery that produces saliva in humans and snakes is still the same today.
