Swine Flu Question

This is gonna be a short post because it's basically a question.

I read that the Swine Flu contains viral code fragments from:
Human influenza
Bird Flu from North America
Swine flu from Europe
Swine flu from Asia

My question is...

How did that happen naturally?

I'm far from being an expert on this subject, so I thought maybe someone out there could give me an explanation.
