Most philosophers agree that abduction (in the sense of Inference to the Best Explanation) is a type of inference that is frequently employed, in some form or other, both in everyday and in scientific reasoning. However, the exact form as well as the normative status of abduction are still matters of controversy.

Following the development of realistic probabilistic models describing the evolution of DNA and protein sequences, the analysis of phyletic pattern data has progressed from the maximum parsimony criterion (Mirkin et al. 2003; Boussau et al. 2004) to models, in which the dynamics of gain (0 → 1) and loss (1 → 0) events are assumed to follow ...15 paź 2016 ...

Philosophers and psychologists make many different, seemingly incompatible parsimony claims in support of competing models of cognition in nonhuman animals. This variety of parsimony claims is problematic. Firstly, it is difficult to justify each specific variety.Our understanding on phytoplankton diversity has largely been progressing since the publication of Hutchinson on the paradox of the plankton.

PAE., More recently, Herbert Simon pointed n Simplicity, Inference and Modelling (2001) to the beauty in “finding pattern, especially simple pattern, in the midst of apparent complexity and disorder.” Simon construes parsimony itself as “pattern in the phenomena” and places it “at the root of what we mean by a scientific law.”, Parsimony methods infer an evolutionary tree by resolving conflicts among the characters.
