Evolution beyond adaptation: a critical step for evolutionary theory

Posted 04 Jul 2015 / 0

The July 2015 issue of Trends in Ecology & Evolution features a really important review article entitled “Selection on stability across ecological scales“. The paper embraces the idea that the stability properties of ecological systems dictate the configuration of extant social groups, interacting species pairs, and overall ecological communities. Lev Ginzburg, my Ph.D. advisor, has Read More

Ben Knight’s “Phyletic gradualism / Punctuated equilibrium”

Posted 03 Aug 2014 / 0

My good friend, artist Ben Knight, has created a nice chart that captures the difference between two different theories of macroevolution: phyletic gradualism and punctuated equilibrium.

Scientific American “Tiny Plants” article provides a primer on the inter-relationship between ecological and evolutionary change

I am always on the lookout for great popular science articles to assign to my students. What makes a popular science article great? Well, to start with it should address concepts that are core to my classes (admittedly, this definition of “greatness” is highly relative to what I decide is important to teach). Concept density Read More

Kavli Institute for Theoretical Physics hosts conference on the role of cooperation in major evolutionary transitions

Posted 17 Jul 2012 / 0

Kavli Institute for Theoretical Physics “Cooperation and Major Evolutionary Transitions” There’s also a seminar series going on this winter: Kavli Institute for Theoretical Physics “Cooperation and the Evolution of Multicellularity” It is fascinating how many physicists are tackling theoretical questions related to cooperation these days!

Macroevolutionary change: do successful lineages have “evolvability” or “survivability”?

Posted 26 Jun 2012 / 0

PLoS One “Survivability Is More Fundamental Than Evolvability” I want to understand this paper better than I do, but there’s almost no burden of explanation taken on by these authors. I get their main point, but have no clue as to how their model allowed them to arrive at this point. I need to hone Read More
