Explain This

Once in a while, I plan to challenge to Adventist scientists and theologians of every stripe, to explain how a certain biological phenomena came to be.

For one nematode parasite, the goal is not to escape, but to be eaten. When it hijacks an ant, it turns its host’s back end as red and prominent as a ripe fruit. “This dupes a bird into feeding on it and getting a mouthful of nematode eggs,” says ecologist Steve Yanoviak. The bird spreads the eggs via its feces, which the ants eat, continuing the cycle. (Pages 86-87, The Art of Deception, National Geographic Magazine, August 2009)
