Actually, from single chambered hearts they may well have. I recently saw a video of a documentary where it was discovered (unintentionally) that a single mutation of a single gene gives rise to a mutation of a single chambered heart to a double chambered one! The geneticists engineered this mutation to see what it's effect would be (they suspected some development in heart evolution, but not as much as they found) and bingo the resulting organism had double chambers where once there was only one!

Of course this only makes stevebee92653's ridiculous arguments even less tenable (if that were indeed possible.)
