There's a new daily wrap-up podcast over at Evolution, Development, and Genomics, and, if you haven't been following the conference on Twitter, check hashtag #evol2010 or this list of twittering attendees I've compiled.
What's going on with snakes, anyway? Photo by Tambako the Jaguar.
- In the SSE symposium, Jenny Boughman and Dan Bolnick discussed ways in which the evolution of sexual dimorphism was like the evolution of different ecological specialists [PDF]—and how males and females evolving different ecological roles can counteract divergent selection acting on the population as a whole.
- In the same symposium, Marguerite Butler showed that correlated neutral evolution of male and female traits may have shaped the diversification of Anolis lizards, using OUCH, a statistical package for R [PDF] that Marguerite demonstrated at the seminar I just attended.
- Luke Harmon presented an impressive but not very conclusive exploration of morphological evolution in squamate reptiles. One insight: once a reptile loses its limbs, its head is free to evolve in new ways, but not always the same ways. Why? Good question.
