Oh evolution, thou art a heartless bitch....
The loss of the organ could have given hens more control over reproduction.
Co-author Dr Martin Cohn, from the University of Florida in Gainesville, said: "Our discovery shows that reduction of the penis during bird evolution occurred by activation of a normal mechanism of programmed cell death in a new location, the tip of the emerging penis."

And, searching on related topics I discovered something I didn't know (or at least have well forgotten) - monotremes have a standard tri-functional cloaca, but marsupials have a cloaca and a separate genital tract.
The diversity of biological adaptation is wonderful. Evolution definitely is the greatest show on Earth.
Thanks for the post, pokerfan. I had read an NBC article on this earlier, but didn't have time then to research further.
