On the origin of the mitochondrial genetic code: Towards a unified mathematical framework for the management of genetic information [PDF]

open access: yes, 2012
The origin of the genetic code represents one of the most challenging problems in molecular evolution. The genetic code is an important universal feature of extant organisms and indicates a common ancestry of different forms of life on earth.

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants

open access: yesAmerican Journal of Botany, Volume 113, Issue 4, April 2026.
Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Primate phylogeny: molecular evidence for a pongid clade excluding humans and a prosimian clade containing tarsiers [PDF]

open access: yes, 2009
Interpretations of molecular data by the modern evolution theory are often sharply inconsistent with paleontological results. This is to be expected since the theory is only true for microevolution and yet fossil records are mostly about macroevolution.

Complex Behavior in Simple Models of Biological Coevolution

open access: yes, 2006
We explore the complex dynamical behavior of simple predator-prey models of biological coevolution that account for interspecific and intraspecific competition for resources, as well as adaptive foraging behavior.

Comparison of musculoskeletal networks of the primate forelimb [PDF]

open access: yes, 2017
Anatomical network analysis is a framework for quantitatively characterizing the topological organization of anatomical structures, thus providing a way to compare structural integration and modularity among species.

Size Disparity in Putative Primate Adaptive Radiations and Other Mammalian Clades

open access: yesAmerican Journal of Biological Anthropology, Volume 189, Issue 4, April 2026.
ABSTRACT Introduction Adaptive radiation is commonly viewed as the rapid production of phenotypic disparity and taxonomic diversity. Among primates, two clades have been identified as potential adaptive radiations: the lemurs of Madagascar and the platyrrhines of the Americas. This study examines these clades for one of the proposed signals of adaptive

Red Queen Coevolution on Fitness Landscapes

open access: yes, 2013
Species do not merely evolve, they also coevolve with other organisms. Coevolution is a major force driving interacting species to continuously evolve ex- ploring their fitness landscapes. Coevolution involves the coupling of species fit- ness landscapes,

Using Marine Snails to Teach Biogeography and Macroevolution: The Role of Larvae and Dispersal Ability in the Evolution and Persistence of Species [PDF]

open access: yes, 2012
While some marine animals are capable of traveling great distances, many have limited mobility as adults and spend the majority of their lifetimes in a small geographical area or may even be cemented to a single place.
