Is this bee solitary or social? The answer may depend on an autism-linked gene

One of biology’s enduring mysteries is how some animals—from humans to honey bees—became so social. Now, a study suggests that, in the inconspicuous sweat bee, changes to the expression of a single gene could determine which bees are solitary and which are social. The gene, which has previously been linked to autism in humans, has also been connected to social behavior in animals like mice and locusts. The new discovery puts scientists one step closer toward demonstrating a common evolutionary basis for social behavior.  Read more...
