In the article, ‘The Role of Climatic Change in the Evolution of Mammals’, in the Teaching Biology section of BioScience , Barnosky & Kraatz (2007) make two claims: evolution is a fact, and fossils are the test evidence of evolutionary hypotheses. In the beginning sentence, the authors state, ‘Despite all the arguments over semantics, evolution is a fact’ (Barnosky & Kraatz 2007: 523), but later claim, ‘Evolution is also a theory’ (Barnosky & Kraatz 2007: 524). This conflation of fact and… 

Evolution as a fact? A discourse analysis

An analysis of the ‘fact of biological evolution’ discourse reveals several overarching agreements among its advocates, but also a contradictory morass of positions regarding how scientific theories, hypotheses and facts interrelate.

Abductive Inference: Implications for ‘Linnean’ and ‘Phylogenetic’ Approaches for Representing Biological Systematization

The ‘Linnean’ system of nomenclature is defective because it fails to promote stability, universality, and unambiguous meaning in the naming of phylogenetic hypotheses, based on the premise that biological systematization should be phylogenetic.

Clarifying the role of character loss in phylogenetic inference

‘ character loss’ is not a problem once it is acknowledged that neither absence nor loss are properties of organisms that systematists perceive or explain by way of phylogenetic hypotheses.

The limits of understanding in biological systematics

The pursuit of ultimate understanding by way of spurious procedures such as contrived testing, Bremer support, and resampling methods are discussed with regard to phylogenetic hypotheses.

Dispelling five myths about hypothesis testing in biological systematics

It is shown that none of the tests discussed by Assis are valid, and while it is straightforward to outline what is required to properly test phylogenetic hypotheses, the feasibility of accomplishing such tests is operationally impractical in most instances.

Phylogenetic Hypotheses: Neither Testable Nor Falsifiable

Crother and Murray criticize the statement by Assis that phylogenetic hypotheses are amenable to testing but not falsification, and claim that both claims are based on long-standing misconceptions about testing developed within systematics.

Species as Explanatory Hypotheses: Refinements and Implications

The formal definition of species as explanatory hypotheses presented by Fitzhugh is emended and it is suggested that species hypotheses can not be applied to organisms with obligate asexual, parthenogenetic, and self-fertilizing modes of reproduction.

Science and Religion: Compatible or Incompatible Explanatory Realms?

For religion and science to exist in a complimentary state, religious theories and hypotheses would have to be limited to explaining non-empirical, supernatural phenomena, while scientific theories and hypothesis are applied to natural phenomena, thus denying the accommodationist position.

Character mapping and cladogram comparison versus the requirement of total evidence: does it matter for polychaete systematics?

It is shown that both character mapping and comparisons of cladograms using partitioned datasets are procedures that severely reduce the credibility of phylogenetic hypotheses.

Definitions offer meanings of words by way of associations with other terms [2, 3]. Accord‐ ingly, a definition relates a concept to a name [4]. Like any field of science, precision of communication



Explanations in evolutionary theory

All phyletic evolutionary change, no matter how extensive it may be, never crosses species taxa boundaries; hence it is not possible to distinguish ‘trans-specific evolution’ (= evolution beyond or above the level of the species) from evolution within the species level.

The Role of Climatic Change in the Evolution of Mammals

Paleontology is used to illustrate the scientific method behind answering complex questions about evolution, and to suggest that current rates of global warming are far too fast to influence evolution much and instead are likely to accelerate extinctions.

The ‘requirement of total evidence’ and its role in phylogenetic systematics

The question of whether or not to partition data for the purposes of inferring phylogenetic hypotheses remains controversial; some phylogeneticists claim the parsimony criterion as justification for the RTE, but there is no relation between the two.

Evolution vs. Creationism: An Introduction

The Unmetabolized Darwin is presented as an introduction to the Pillars of Creationism and Evolution in the Media and a history of the Creationism/Evolution Controversy is presented.

The inferential basis of species hypotheses: the solution to defining the term `species¿

A formal definition of the term ‘species’ is presented that is logically consistent with the inferential structures that lead to other taxonomic categories in biological systematics and acknowledges species as representative of explanatory hypotheses.

The Logic of Discovery: An Analysis of Three Approaches

Is there anything about the discovery of scientific theories that is of legitimate concern to the philosopher of science? The answer to this question is still controversial. Popper (1959), Hempel

DNA and the Origin of Life: Information, Specification, and Explanation

Since the late 1950s and 1960s, origin-of-life researchers have increasingly recognized the complex and specific nature of unicellular life and the biomacromolecules on which such systems depend and characterized this complexity and specificity in informational terms.
