What is a species? Philosophy, Science and Scicomm

What is a species? This apparently simple question is one of the best ways to get scientists arguing.

A recent article by Henry Taylor, a philosopher at University of Birmingham, asks this question from a philosophical perspective. The article itself is okay. But there is zero chance of biologists adopting its recommendation, ‘to scrap the idea of a species’, any time soon (see also this older article at the same platform, on the same subject, from a biologist’s perspective).

What I found interesting is how different audiences interpreted the article in the comments and on social media. I saw a mix of reactions (based on my network and a few searches; obviously not indicative of everyone) – some scientists were condemning the article vocally and aggressively, while others who didn’t appear to be scientists (based on their Twitter bio), shared the article in agreement and support.

‘What is a species?’ is a classic philosophical question, not a scientific one. Philosophical questions are a valuable tool for life. They are conceptual, not factual; they are rarely ‘solved’ (in the scientific sense); and they need to be addressed with complex thinking, not just facts or empirical research. You don’t have to agree with this approach, it’s just how Philosophy differs from Science. Disciplines are defined by different methodologies, standards, systems, and norms.

Times have changed: dealing with dodgy science in the internet age

Dodgy science, dodgy scientists and dodgy humans are not a new thing. And dodgy scientific papers have been published since the dawn of scientific publishing. In 1667 an article on ‘snakestones’, a pseudoscience medical cure with absolutely no basis in truth, appeared in one of the first issues of the oldest known scientific journal, Philosophical Transactions of the Royal Society (now Phil Trans A, one of the most prestigious modern scientific journals).

Since then, disreputable papers have made regular appearances in reputable journals. And there are different scales of disreputable. The paper claiming that octopi originated from outer space was clearly far-fetched, while the scholars who recently argued there was a ‘moral panic’ over free-ranging cats simply highlighted how interdisciplinary research is often challenged by opposing methodological approaches (note: I agree with most ecologists that free-ranging cats are not good for wild animals, including insects).

On the conservation of single-author papers

The number of authors included on research papers in many disciplines has increased over time. This editorial in Journal of Applied Ecology is the latest analysis of this trend, finding that published single-author research papers in that journal have declined since 1966 (two years after the journal started publishing). N.B. the authors only quantify research papers (i.e. data papers, but they don’t specify if they include reviews/meta-analyses…see below), and applied ecology should be a multidisciplinary field, so this is a good thing.

The editorial is excellent, and you should read it – the discussion of underlying causes of this trend is mostly reasons why we should encourage more multi-author papers.

But…there will always be a place for single-author papers in research, especially for early career researchers. Continue reading
