About 2 to 3 million years ago, a group of spiders let out long silk threads into the wind and set sail, so to speak, across the Pacific Ocean to Hawaii. These spiders were parasites of other spiders, invading their webs, ...

(Phys.org) -- Fruit flies are commonly used in genetics research because their lifespan is short, they are easy to breed in the laboratory, and mutants are widely available. There are about 1,500 known species. Now a new ...
An international team of researchers, led by scientists at the University of California, San Diego School of Medicine, suggest that inactivation of two specific genes related to the immune system may have conferred selected ...

According to classical ecology, when two species compete for the same resource, eventually the more successful species will win out while the other will go extinct. But that rule cannot explain systems such as the Amazon, ...
