Scientists described the first evidence of a possible respiratory illness in a fossil. The common soil fungus Aspergillis can infect birds and reptiles today. The resulting disease, also called aspergillosis, causes the trachea’s soft tissues to attach to nearby bones. This causes odd bone bumps—the subject of discovery in a dino nicknamed Dolly.

The standard evolutionary theory is that humans evolved from a chimp-like ancestor about 3 to 6 million years then migrated out of Africa about 100,000 to 200,000 years ago.

Graduate student Shiuan-Tze Wu led a study of some ingenious organization into the odor-sensing cells of fruit flies. He and his collaborators at the La Jolla campus of UC San Diego found that the odor-detector cells in the insects’ antennae talk to one another in a way that saves brainpower.

Evolutionary scientists discovered an ancient tsunami victim and a dog skeleton at ÇeÅŸme-BaÄŸlararası, a settlement on the coast of Turkey.¹ The researchers also found numerous marine shells mixed within the enveloping sediments, indicating that the waves washed in from the ocean.
