For around 10,000 years, humans have selectively bred sheep for desirable traits. Generation after generation, we have chosen animals for their wool, size and reproductive characteristics and gradually left our mark on their DNA.

Evolution found another way to build a primate brain

What makes the human brain so much larger and more complex than the brains of many other mammals? Scientists have long sought clues in our DNA. Some discoveries show how genetic changes enable the developing brain to produce more cells. Others help explain how long those cells ca

How Chinese brewers refined their booze 5,000 years ago

More than 5,000 years ago, brewers in eastern China appear to have used red mold to make rice alcohol, then strained the drink through cloth. Microscopic residues on ancient pottery show evidence of both the fermentation method and the filtering process to separate the liquid fro
