Think your DNA is 100 percent Homo sapiens? Think again. A recent study in the journal Nature reports that at least 40 million years ago, our primate ancestors "invited" a gene from an infecting virus into their genomes. Because this phenomenon adds novelty to a species' DNA makeup, it may represent a newly discovered mode of evolutionary change.

It's quite subtle. Nearly imperceptible. Not where we might think of looking first: how we see ourselves—our identity—shapes our future as a species. So let's tell a story about ourselves—let's build a cultural identity that moves us to dream bigger, learn faster.... go places, evolve into something even better.
