Some researchers delving into the origins of life have sex on the brain. The prevailing thought in the field says that sex, typically defined as reproduction involving the fusion of genomes, emerged no more than 1.2 billion years ago. This is when eukaryotes, often haughtily considered the only organisms privileged enough to partake, evolved. But some are broadening the definition of the natural act and implicating it in life's origins. Others warn that this is ill advised.
