Macroevolution: Dynamics of Diversity [PDF]
Current Biology, 2011 The fossil record typically exhibits very dynamic patterns of innovation, diversification and extinction. In contrast, molecular phylogenies suggest smoother patterns of evolutionary change. Several new studies reconcile this difference and reveal more about the mechanisms behind macroevolutionary change.

The Origin and Diversification of the Hyperdiverse Flora in the Chocó Biogeographic Region
Frontiers in Plant Science, 2019 Extremely high levels of plant diversity in the American tropics are derived from multiple interactions between biotic and abiotic factors. Previous studies have focused on macro-evolutionary dynamics of the Tropical Andes, Amazonia, and Brazil’s Cerrado

Micro- and Macroevolution: A Continuum or Two Distinct Types of Change? [PDF]
How microevolution and macroevolution are related is one of the major unanswered questions in evolutionary biology. The most prevalent view is that microevolution and macroevolution are part of a continuum of one type of change and that macroevolution is

Cellular Automata Model of Macroevolution
, 2008 In this paper I describe a cellular automaton model of a multi-species ecosystem, suitable for the study of emergent properties of macroevolution. Unlike majority of ecological models, the number of coexisting species is not fixed.

Evolution as a Largely Autonomous Process
, 2015 Evolutionary theory has proven generally successful in predicting phenotypic changes over one or a few generations of natural or artificial selection, but fails to predict evolutionary dynamics over longer periods of time, which is a major shortcoming ...

Gould on Species, Metaphysics and Macroevolution: A critical appraisal
, 2018 Stephen Jay Gould's views on the ontology of species were an important plank of his revisionist program in evolutionary theory. In this paper I cast a critical eye over those views.

The effects of a professional development program on elementary and middle school teachers’ understanding and acceptance of macroevolution and how they teach it [PDF]
, 2014 textDespite science education reform efforts stressing the importance of understanding evolution, many students receive little to no exposure to the most important unifying concept in biology.

The Grasses: A Case Study in Macroevolution
, 2000 ▪ Abstract Macroevolution in the grasses has often involved change in the position (heterotopy) of developmental programs, possibly via ectopic gene expression.
