Professor Grant (1989) argued that in my recent note on the role of species in anagenesis (Futuyma 1987), I have independently discovered his principle of "speciational trends," and he noted the failure of younger authors to cite precedents in the older literature for their ideas. Although I strongly advocate a historical perspective on one's field and attempt to live up to this ideal, I must admit to overlooking some points of similarity between Grant's ideas and my own, although I was… 
Peripatric speciation
The existence of peripatric speciation is supported by observational evidence and laboratory experiments, and scientists observing the patterns of a species biogeographic distribution and its phylogenetic relationships are able to reconstruct the historical process by which they diverged.
The role of standing variation in geographic convergent adaptation
The results suggest that much of adaptation may be geographically local even when selection pressures are homogeneous, and argue that caution must be exercised when arguing that strongly geographically restricted alleles are necessarily the outcome of local adaptation.

It is possible to feel such communion with the works of our scientific predecessors as to inspire not only admiration, but also gratitude and even affection. Long before I met him, Ernst Mayr had
The Role of Standing Variation in Geographic Convergent Adaptation*
This article explores how standing genetic variation contributes to convergent genetic responses in a geographically spread population, and derives the geographic scale over which an allele dominates and the proportion of adaptive alleles that arise from standing variation.
Taking Evolutionary Transitions Seriously
A simplified taxonomy of biological and evolutionary transitions stemming from two complementary conceptual views of biological evolution, that of Brooks and Wiley (1988) and of Maynard Smith and Szathmary (1995) are proposed.
The Major Metaphors of Evolution: Darwinism Then and Now
This book argues that a return to Darwinism to recover useful but discarded ideas and to extend it forward while removing barriers between specialized areas of research to integrate new ones is needed.

Species, lineages, splitting, and divergence: why we still need ‘anagenesis’ and ‘cladogenesis’
The concepts and terms of anagenesis and cladogenesis are still needed and very useful as descriptors of evolution.
Phylogenetic Insights on Adaptive Radiation
  • R. Glor
  • Biology, Environmental Science
  • 2010
How modern phylogenetic analyses are central to defining and diagnosing adaptive radiation is discussed, as well asdiagnosing predictable patterns of ecological diversification during adaptive radiation, and reconstructing the history of adaptive radiations are discussed.
Networks and Hierarchies: Approaching Complexity in Evolutionary Theory
It is suggested that a pervasive pattern of stability in living systems across scale results from the architecture of nature’s economy itself—biological systems consisting of hierarchically nested, complex networks are extremely robust to extrinsic perturbations.


On the Role of Species in Anagenesis
It is proposed that because the spatial locations of habitats shift in time, extinction of and interbreeding among local populations makes much of the geographic differentiation of populations ephemeral, whereas reproductive isolation confers efficient permanence on morphological changes for them to be discerned in the fossil record, a consequence of speciation that supports a highly qualified version of punctuated equilibrium is pointed out.
The Theory of Speciational Trends

The subject of speciational trends is reviewed here for several reasons, since it can explain some macroevolutionary phenomena that are difficult o account for by any other process.
Genetic Revolutions, Founder Effects, and Speciation
It is argued that, although founder effects may cause speciation under sufficiently stringent conditions, they are only one extreme of a continuous range of possibilities, and divergence may be driven in a variety of ways, without the need for drastic external changes.
