The first humans on Mars will quickly become too fragile to have sex with. That's according to one scientist, who reckons colonists will warp into super-mutants who'll keel over the moment they sleep with an Earthling. NASA is keen to land humans on Mars in the 2030s with an eye on setting up a permanent Martian colony. According to Professor Solomon, who is an evolutionary biologist at Rice, it will only take Mars colonists two generations to become super-mutants. "Evolution is faster or slower depending on how much of an advantage there is to having a certain mutation," Professor Solomon says.
