How could the current H1N1 “swine flu” variation develop naturally?
Considering that the current H1N1 "swine flu" is actually a combination of swine flu, avian flu and human flu strains from different continents, I would like to have a scientific explanation of how it is possible for this "triad" flu strain to have developed naturally.

The Centers for Disease Control and Prevention(CDC), and World Health Organization(WHO), agree that it was caused by a pig who got both swine, and avian flu. It gave it to a human, and while infected, the human got Human flu. This caused the flus to "merge", and created H1N1 A flu.
Influenza viruses can infect multiple species of animal.
This is really not hard. Birds migrate, they take the flu with them. Humans travel they take the flu with them.
An Asian bird migrates to Europe taking a bird flu with them. That flu finds it’s way into a human who gets "bird flu" and infects others. One of the poor unfortunate souls who picks up this "bird flu" is a sick elderly person who already has a form of human flu.
The two flu’s combine and infect healthcare workers, then the healthcare workers kids, then the healthcare workers kids classmates, then the healthcare workers kids classmates parents. One of those parents gets infected, travels to Mexico on vacation, and passes this "combined flu" to one of the workers in the hotel. That worker passes it to their families.
One member of their family is already infected with a form of swine flu. That family member is now infected with a combination swine-bird-human flu.
This is not all that uncommon. What is uncommon is for these combined flu’s to spread so late in the flu season. Which theoretically ends in mid-Spring.
