When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.

One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.

But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.

To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.

Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

Product Description
In the 150 years since the publication of Origin of Species, Charles Darwin has been considered between two extremes--- a great biologist or heretic（持异端学说者）. However, the truth is much more difficult to understand than that. In any case, Darwin’s theory of evolution and natural selection had the greatest influence in history.
In The Darwin Myth，author Benjamin Wiker offers a full-side analysis of Darwin’s theories as well as the social, scientific, and religious effect of his work. Scientists often cause debates(争论) that will last for generations for their new theory. Still, no scientist has caused more debates than Charles Darwin. To some he is the revolutionary “father” of evolution. To others his theory of evolution unconsciously disagrees with many ideas in modern eugenics.（优生学） In The Darwin Myth: The Life and Lies of Charles Darwin, author Benjamin Wiker will make them clear.
