Something must happen to ‘stir up their heredities,’ as I am fond of saying—to excite in them the variability that normally lies dormant, Burbank later explained
Some ancient eukaryote swallowed a photosynthesizing bacteria and became a sunlight gathering alga. Millions of years later one of these algae was devoured by a second eukaryote. This new host gutted...
Skinner and his colleagues launched a new study to see how far this effect could get passed down. They exposed more female rats to vinclozolin and then bred descendants for several generations. Even a...
Since hominin skin doesn’t fossilize, we can’t say for sure what skin color our ancestors had four million years ago. But if our closest living primate relatives—gorillas and chimpanzees—are any guide...

Dolphins may even be able to name each other with signature whistles. But their society may nevertheless be one of an overlapping network of minds, wandering linked through a transparent ocean.
Based on their research, the Sanger scientists estimated that an embryo gains two or three new mutations every time its cells double.
According to Goddard’s standards, 47 percent of the white soldiers and 89 percent of the blacks should be categorized as morons. The average white soldier, the psychologists found, had a mental age of...
