10:38 PM | What do you do on a Friday Evening?! Apparently I Learn About Duck Sexual Organs!
So I just finished watching a film and was just looking through my tumblr when I cam across the cartoon above. I had guessed that it was referring to a ducks penis but curiosity and wanting to check the facts got the better of me. A quick Google search brought up an article from sciencedaily.com […]

9:09 PM | Sexual Healing in Bonobos
Bonobos have earned a reputation as a “sexy” ape. Sexual activity — in many creative forms — plays a large role in bonobo society. Sexual contacts occur often, in virtually all partner combinations and in a slew of different positions. Read my latest Zoologic post, a Q&A with Emory University’s Zanna Clay about her research looking at how bonobos use sex to break the tension after conflicts: Sexual Healing: How Bonobos Use Sex to De-Stress .

Happy Fun Science Friday. You did not mistakenly read the title, today we bring you the discovery of the first female penis in the animal kingdom. Yoshizawa, from Hokkaido University in Japan, and his team of researchers documented this phenomenon of sexual role reversal in 4 species of rather unassuming insects in Brazil’s Peruaçu River Valley.

1:56 PM | A week of links
Links this week: It’s from late last year, but this piece on the biological origins of morality is worth reading. A new journal, Economic Anthropology, with the debut issue on greed and excess (and sorry, gated for those without academic access). Diane Coyle points to some older work on wealth and inheritance. She also pointed […] The post A week of links appeared first on Evolving Economics.

12:00 PM | Which Shall Live and Which Shall Die? Conservation Triage for Birds
There’s a struggle at the core of wildlife conservation between our desire to help and our ability to help. It’s a mismatch between the seemingly unending flow of species from existence to extinction and the limited resources at our disposal for use in stopping that flow. On the one hand, we could try to spread

1:33 PM | Bill Nye on the Inside Story of the Nye-Ham Debate
You will recall that last February, Bill Nye, the Science Guy, debated Ken Ham, the Not-So-Science Guy, on the question of creationism as a viable explanation for the Earth’s history. The debate was held in Ham’s home territory, at the infamous Creation Museum in Kentucky. Nye didn’t really debate Ham. He ate him for breakfast.…

7:45 PM | Our brain is not programmed to reading or writing
The title is certainly somehow confused, but here I'll explain you how I came up to this.I am advisor of a very intelligent woman who is studying musical cognition and her work proposes a relationship between the processes of reading and writing music and natural language. We have written a couple of articles which we hope to publish soon, but while we were working with her thesis I made comments, and about a paragraph I wrote her the following note: remember that our brain is not […]

6:14 PM | Evidence-based skepticism in the spotlight thanks to Bill Nye’s debate
It’s so very exciting to see the reverberation of the Creation-Evolution debate continuing. And I am very happy to see Skeptical Inquirer play a role in it. This current issue of SI has an exclusive piece written by Bill Nye, The Science Guy himself, discussing the behind-the-scenes goings on that took place before and during… Source: Doubtful News

How is variation maintained in populations? This is a bit of a poser for evolutionary theory, especially in the realm of sexual selection. If males or females of a certain type always score highest in contests of mate choice, genes … Continue reading →

1:17 PM | Journal Club: What’s old is new again: newly discovered songbird family is ancient
SUMMARY: Scientists analysing songbird DNA discovered that the spotted wren-babbler is neither a wren nor a wren-babbler, nor even a babbler. Instead, it represents an old evolutionary family that has no close living relatives. Spotted wren-babbler, Elachura formosa (previously Spelaeornis formosus). Image: Per Alström/SLU [doi:10.1098/rsbl.2013.1067]. A newly published study has uncovered a previously unknown family of songbirds that is represented by just one species. After analyzing one […]

9:26 PM | Bill Nye’s Own Take on the Nye-Ham Creationism Debate
Bill Nye’s Own Take on the Nye-Ham Creationism Debate: Read Bill’s full account here. Perhaps there was no winner, as this was not a scored debate. Nevertheless by all, or a strong majority of, accounts, I bested him. The fundamental idea that I hope all of us embrace is, simply put, performance counts as much or more than the specifics of the arguments in a situation like this. I admit that, for me at least, it took tremendous concentration. I was and am respectful of Ken […]
