From Nature comes “Ostrich penis clears up evolutionary mystery.” To quote:
A long-running question about how the largest species of birds achieve erect penises seems to have been settled. In a study published this week in theJournal of Zoology1, researchers report that male ostriches and emus enlarge their penises using a burst of lymphatic fluid rather than a blood vascular system like that found in reptiles and mammals.
The finding, based on dissections, matches what is known about other species of birds — only 3% of which have penises — and could have important implications for the understanding of the shared, and divergent, evolutionary heritage of birds and reptiles.
I guess something to share with others at the Holiday cocktail parties. And yet another reason why we should be the emus and not the eagles.

I will be out of town at a conference starting later today, and thus not posting to EMUTalk. Along these lines, I’m planning on taking a complete month off from the site in June. No particular reason, and I don’t plan on taking a month long computer “fast” or anything like that, but I will be doing some more traveling then too, and a little “va-kay” seems in order.
