To love, honour and deceive

Long-term relationships are fundamentally dishonest. And it's all the fault of females.

The researchers claim that by offering sex anytime, but no clues as to whether they will conceive, females trick males into hanging round for a long time. The evolution of this deception is the only reason that monogamy has developed.
