With Ben Bartlett (Dept. of Physics, Stanford), Michael Goldsby (Philosophy, WSU), & Todd Nagel (Philosophy, Western): Brandon's arguments that genetic drift constitutes the inertial state for evolutionary biology are faulty. Applying Brandon's criteria, drift constitutes an evolutionary force.

A critical analysis of the use of mtDNA barcoding and the Multi-Species Coalescent for species delimitation. New data and methods enable splitting lineages on the basis of more or less ephemeral population structure.

I trace the connection between parsimony vs. likelihood, taxonomic congruence vs. simultaneous analysis, and concatenation vs. coalescence debates, via the principle of total evidence.

I explicate the claim that one family of computational models in contemporary studies of biodiversity (concatenation) constitutes a special case of a more general set of models (coalescence). I clarify Edwards et al.'s (2016) claims that phylogenetics is a "special case" of population genetics. By comparison with earlier debates and mathematical reductions, I show that (pace Edwards) the concatenation vs. coalescence disputes reflect competing paradigms. The debate turns on competing interpretations of "first principles".

I analyze analogies of the units of genetics to the units of chemistry, focusing on William Bateson. Bateson did not intend an empirical claim about the nature of characters, genes, or species, but rather a theoretical claim that he hoped would advance the science of genetics. I also demonstrate that Bateson thought that species were not regarded as fixed entities until the eighteenth century, and that the fixation of species was an important scientific advance. Bateson expected his readers to understand his analogies in light of this historical background.

This paper clarifies substantial confusion in use of the term "cladist" by biologists and philosophers. Resolving this confusion reveals what is at stake in ongoing debates between proponents of distinct mathematical models for studying biodiversity.

I analyze Whewell's attempts to impose order on classificatory mineralogy, in Whewell's day (1794-1866) a confused science of uncertain prospects. By comparison with biological classification, Whewell proposed methodological reforms that he claimed would lead to a natural classification of minerals, which in turn would support advances in causal understanding of the properties of minerals. Whewell's comparison to successful biological classification is particularly striking given that classificatory biologists did not share an understanding of the causal structure underlying the natural classification of life (the common descent with modification of all organisms).

What did pre-Darwinian biologists think they were doing when they made claims about species and relationships between species? And how did they get anything right? Girard argued for three distinct forms of natural relationship, which compelled him to represent biodiversity via diagrams intended to be read in three dimensions.

Whewell developed a theory of historical inference: how to make and defend scientific claims about what happened in the past. Following Darwin's publication, biological inference changed in some of the ways that Whewell analyzed. Karl Gegenbaur reasoned about the construction of organisms in much the same way that Whewell reasoned about the historical development of Gothic architecture.

Biologists who study biodiversity have devised a formal structure of inference that answers the bad lot objection to abductive inference. Modern computational approaches to biodiversity provide methodological solutions to this philosophical challenge.

We used morphological, genetic, and bioegeographic analyses to review the genus Bassaricyon. We discovered the first new species of Carnivore in the Western hemisphere in 35 years. The Olinguito was named one of the Top 10 New Species of the year by the International Institute for Species Exploration, and our paper is currently the all-time most downloaded paper in the journal.

I critique the view that scientists use causal theories to hypothesize what past chains of events must have been, and then form hypotheses that identify segments of a network of events and causal transactions between events. Twentieth century philosophers of science tacitly adopted this assumption in otherwise distinct models of explanation. As Whewell pointed out in his critique of J.S. Mill, the problem with this assumption is that the delineation of events via properties is itself the hard part of science. Whewell’s account of historical science and of consilience provide a better foothold for understanding the study of biodiversity after Darwin’s revolution as a form of abductive inference. I conclude by showing how two challenges that are frequently pressed against abductive inference are met in the context of phylogenetic inference.
