Visualizing Macroevolution

The adaptive landscape is an important diagrammatic concept that was conceived in population genetics. During the Modern Synthesis, in the first half of the Twentieth Century, the landscape imagery was used to represent evolution on a large scale, aiding in the construction of a common language for a new evolutionary biology. Not only historic adaptive […]

The landscape metaphor in development

“It seems that the landscape metaphor will continue to stay with us, at least for a while”. We start defining a landscape as a function of multiple variables and show how this can be interpreted as a dynamical system. From the perspective of dynamical systems modelling, we move to analyze Waddington’s ‘epigenetic landscape’ and landscape […]

University of Sydney HPS Research Seminar Series

For 80 years now, a famous and influent picture have been around in evolutionary biology: it is the adaptive landscape, a hilly or rugged surface with peaks and valleys onto which combinations of traits are mapped, the elevation representing the fitness value of these combinations. As a communication and heuristic tool, the adaptive landscape well […]

Criticizing adaptive landscapes, ecology and genealogy

Disentangling ecological vs. genealogical dimensions is a core task of hierarchy theory in evolutionary biology. As Eldredge repeatedly epitomized, organisms carry out (only) two distinct kinds of activities: they survive, and they reproduce. At the organismal level, the organism stays the same whether we consider it ecologically or genealogically – yet, differences can occur in […]

PhD Dissertation

This dissertation brings a contribution to the philosophical debate on adaptive landscapes, an influent “model” or “metaphor” in evolutionary biology. Some elements of innovation are: the distinction between native and migrant metaphor; a processual and communicational idea on what the Modern Synthesis was, and on what role a metaphor could have played in it; a […]
