Why do you think they 'evolved' to have such an 'illusion'? Is it not absurd to think that 'illusions' have an evolutionary efficacy?
Zoon: Plenty of illusions have evolutionary efficacy, for example, eye spots on the wings of butterflies probably evolved to give predators like birds the illusion that a large and fearsome animal is looking at them.
Robert Trivers, a respected evolutionary scientist, has recently written a book “Deceit and self-deception: fooling yourself the better to fool others” about the possible survival value of self-deception, which would be an example of an evolved cognitive illusion in humans. He first put forward this suggestion about thirty years ago, and many researchers take it seriously.

As ever, free will has multiple definitions. I would say that the basic definition is metaphysical, that people have some essential freedom, beyond merely social freedom. I was also stretching the term to refer to the social freedom which members of a human group give to each other. I think the social freedom is real (and important for functioning human groups), and that the metaphysical freedom is an illusion but a useful one.
If it is important for the stability of a human group that all the members should be careful to allow each other freedom of action (within limits), then an illusion that all people who count as group members have, by their nature, a core essence of freedom which ought morally to be protected, might well be a useful illusion. Groups whose members were less likely to try taking advantage of each other, or were more likely to be attacked when they did try it, may well have been less liable to internal dissention than other groups.

Which sort is the free will sort is what all the fuss is about. (And what a fuss it has been: philosophers have debated this question for over two millennia, and just about every major philosopher has had something to say about it.) Most philosophers suppose that the concept of free will is very closely connected to the concept of moral responsibility. Acting with free will, on such views, is just to satisfy the metaphysical requirement on being responsible for one's action. (Clearly, there will also be epistemic conditions on responsibility as well, such as being aware—or failing that, being culpably unaware—of relevant alternatives to one's action and of the alternatives' moral significance.) But the significance of free will is not exhausted by its connection to moral responsibility. Free will also appears to be a condition on desert for one's accomplishments (why sustained effort and creative work are praiseworthy); on the autonomy and dignity of persons; and on the value we accord to love and friendship.
This suggests strongly that free will is primarily a social concept, based on people’s reactions to each others’ behaviour. If someone has free will then they are morally responsible for their actions, which cashes out in physical, evolutionary, terms as other members of the group ganging up on them if they misbehave (edit: small children or mentally disabled people, who are not accorded free will, are controlled at all times but are less likely to be punished if they misbehave –the controller, e.g. the parent is more likely to be punished if the misbehaviour was serious). The idea may be metaphysical, but the practice is solidly physical, with a clear evolutionary rationale. Likewise, if a person with free will behaves well, e.g. shows sustained effort or produces creative work, then they can expect praise and other rewards from the rest of the group. Again, the idea of praise may be metaphysical, but the rewards are likely to be translated into greater reproductive success.
