When it comes to sex, we are consumately proximate

Posted 20 Sep 2015 / 0

The Guardian “Why the UK sperm bank is running short” Further evidence that while we are — on the one hand — one of the weirdest species in the world, at our core we remain not unlike the rest of our animal brethren. Think about it for a second: if humans were both rational and Read More

The most fundamental way in which culture pushes against biology

Posted 26 Aug 2015 / 0

National Public Radio “For Prospective Moms, Biology and Culture Clash” Seven years later, I need to check and see how these American demographic trends have developed. Are even more women having babies later in life? Interesting thing here is how big a tension there is between our cultural choices and our biological realities. If fertility peaks Read More

Evolution 2014: Day 0

Posted 20 Jun 2014 / 0

I started off this year’s Evolution meeting early. The conference is — at its core —  a four-day affair. But the days leading into the “official” start on Friday evening feature larger workshops aimed at building skills. I chose to attend the Experiencing Evolution workshop. Here’s what this session promised: Evolution is a key biological concept, Read More

Barash the gene accountant on that little economic driver called “reproduction”

Posted 25 Oct 2013 / 0

The Chronicle of Higher Education “Sex on the Mind” Ugh. How do I decompose this enough? I have always had a fear that David Barash is more pundit than academic, but this column is really scary. There is complete agreement among evolutionary biologists that all we need to understand the evolutionary process is a consideration of Read More

Cooperative child-rearing pays dividends for ruffed lemurs, irrespective of kinship

Posted 23 Aug 2013 / 0

Mongabay News “The evolution of cooperation: communal nests are best for ruffed lemurs” Behavioral Ecology and Sociobiology “Communal nesting, kinship, and maternal success in a social primate” What I find particularly interesting about these findings is that they appear to show that kinship — if a factor at all — might well be a byproduct Read More

Barash not so enlightening on the paradox of human homosexuality

Posted 02 Jan 2013 / 1

The Chronicle of Higher Education “The Evolutionary Mystery of Homosexuality” It is interesting that Barash focuses so heavily in this article on traditional population genetic explanations for the “paradox” of homosexuality, especially when it is becoming so clear that single-gene approaches to human evolution make very little sense. Barash also makes a really weak argument Read More
