I agree that humans may have evolved a "well developed sense consciousness" -- as individuals.
Ants, from another perspective, may have evolved a well developed sense of consciousness as social entities or "superorganisms".
In both cases, individual and social (colony or species) survival are motivating factors.
"happiness seems to be practically synonymous with goals – that which we desire to have. Although many seem to find, in some cases anyway, that the pursuit is more of a pleasure that its attainment."

In my hedonistic theory, pleasure and pain perceptions (in the brain) are dynamic processes that reflect the direction of achievement or loss, and are motivating factors. Therefore, I agree that pursuit in the "right" direction is pleasurable, and a complicated (multi-factored) set of perceived attainment leads to "happiness" -- for awhile.
