A current list of species concepts

As part of my book, I have updated the list of species concepts. Thought you lot might like this: Species conceptions Basic Convention Taxonomic species [TSC] Diagnostic Morphospecies [MSC] Genealogy Evolutionary species [ESC] [Monophyly] Phylospecies [PSC] Gene-based Genetic species [GSC] Reproductive reach Biospecies [BSC] Ecological niche Ecospecies [EcSC] Replacement concepts Operational Taxonomic Units Least Inclusive Read More…

Species: The evolution of the idea

My revised book is now titled Species: The evolution of the idea, and now contains a philosophy section as well as a complete list of species concept[ion]s and an appendix of all taxonomic levels I could locate. It is due out in February 2018 from CRC Press. I have done a complete revision of all sections Read More…

Species: The evolution of the idea

I have completed and submitted the manuscript now for my revision of Species: A history of the idea, now renamed Species: the evolution of the idea. I am publishing it with CRC Press, and it is due out next year. In addition to updating and revising the historical sections of the book, I have added Read More…

A nineteenth century view on classification

The principle upon which I understand the Natural System of Botany to be founded is, that the affinities of plants may be determined by a consideration of all the points of resemblance between their various parts, properties, and qualities; that thence an arrangement may be deduced in which those species will be placed next each Read More…

Wilkins on philosophy of science

As part of the Science Week activities that informed the last few posts, I will be giving a brief introduction to philosophy of science as well as talking about the relation between science and religion shortly. The organiser of this event (on 23 August, at the East Melbourne Unitarian Church) is Adam Ford, who interviewed Read More…

Book review: Understanding Evolution

I posted this on Panda’s Thumb, but I thought I would repeat it here. I occasionally get books for review unsolicited, and many of them are not worth noticing. However, Kostas Kampourakis’ Understanding Evolution is a wonderful resource for students of all kinds, including biology students. Kampourakis, a philosopher at Geneva, has compiled and discussed sensibly a Read More…

Speciation – a brief history: Linnaeus

One of the fundamental aspects of evolution is speciation. This is the process by which more species come into being, and there are many different definitions and mechanisms that have been proposed by biologists in the last couple of centuries. I aim to write an occasional series on what it is supposed to be at Read More…

Natural classification

It occurs to me that I haven’t plugged my own book here. What a failure on my part! It was published in December, so it is really time I did so. In this book, Malte Ebach and I discuss a topic not often discussed in the philosophy of science: the classification of nature in the Read More…

Are species theoretical objects?

[Note: this is a paper that has sat in my drawer for a while now. I am posting it to follow from my last post on the theological origins of species. If species are not ranks in biology, what are they?] It is often claimed that species are the units of evolution, but this is Read More…

Articles of faith: The theological and philosophical origins of the concept of species

It takes a while for the implications of one’s own work to sink in. In my 2009 book Species, a History of the Idea (see here), I argued that the notion that before Darwin people were essentialistic and fixist about species was false. A recent paper by Jack Powers about Mayr’s misreading of Plato complements an earlier Read More…
