Why Don't Humans Have a Mating Season?

Deer, dogs, cats, and whales all have mating season in fact most mammals do, but why don't humans? According to the Naked Scientists forum, humans have evolved much more than other mammals not to need a mating season. Many animals reproduce at a certain time of the year because of their food resources or the temperature changes that they experience throughout the year. Animals want a lot of food available for the pregnant and nursing mother to stay nourish her and obviously don't want their little bundle of joy freezing at the time of birth.

Humans, in most cases, will not starve during pregnancy and their babies will stay warm even if they're born in the middle of December. So in this case there is no real reason for humans to have a mating season. If all these factors are taken care of the babies will survive whether they were conceived in January or July.

Another, more interesting theory is beer. According to Nkruman Steward, "if it wasn't for beer, humans would have a mating season just like every other animal on the planet." He believes there is no need for a mating season for humans because after a six pack of Bud Light, we can jump start one for ourselves at any time. Alcohol stimulates the part of the brain that determines facial attractiveness. In studies by researchers at University of Glasgow and St. Andrews, they found that the more people drink, the higher they ranked pictures of the opposite sex. So apparently people get drunk and reproduce; therefore, leaving no need for a mating season.

The beer theory is interesting and may have some explanation of why humans do not need a mating season, but I think the human evolution theory is more accurate.
