We explore the evidential relationships that connect two standard claims of modern evolutionary biology. The hypothesis of common ancestry (which says that all organisms now on earth trace back to a single progenitor) and the hypothesis of natural selection (which says that natural selection has been an important influence on the traits exhibited by organisms) are logically independent; however, this leaves open whether testing one requires assumptions about the status of the other.

Did Darwin write the Origin backwards?
  • E. Sober
  • Biology, Medicine
  • Proceedings of the National Academy of Sciences
  • 2009
TLDR
It is argued that common ancestry has evidential priority, and it is raised the question of why Darwin puts natural selection first and foremost in the Origin. Expand
ASSESSING CURRENT ADAPTATION AND PHYLOGENETIC INERTIA AS EXPLANATIONS OF TRAIT EVOLUTION:THE NEED FOR CONTROLLED COMPARISONS
TLDR
It is shown that the method of controlled comparisons can be viewed as a meta‐method, which can be implemented in many ways, and is illustrated by an analysis of sex‐ratio data for fig wasps, which suggests that current adaptation and phylogenetic inertia influence this trait. Expand
Darwin's Diagram of Divergence of Taxa as a Causal Model for the Origin of Species
  • J. L. Bouzat
  • Biology, Medicine
  • The Quarterly Review of Biology
  • 2014
TLDR
It is argued that Darwin's Diagram of Divergence of Taxa represents a broad conceptual model of Darwin's theory, illustrating the causal efficacy of natural selection in producing well-defined varieties and ultimately species. Expand
A Comparative Method for Studying Adaptation to a Randomly Evolving Environment
TLDR
It is shown how both evolutionary and optimal regressions, as well as phylogenetic inertia, can be estimated jointly by a comparative method built around an Ornstein–Uhlenbeck model of adaptive evolution. Expand
Tales of Tools and Trees: Phylogenetic Analysis and Explanation in Evolutionary Archaeology
TLDR
It is argued that, while archaeologists have claimed that “cladistics is useful for reconstructing artefact phylogenies” (O’Brien et al. 2001), these reconstructions only contribute minimally to the explanatory research agenda of evolutionary archaeology. Expand
Is Drift a Serious Alternative to Natural Selection as an Explanation of Complex Adaptive Traits?

‘There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—theExpand
Permutation tests for comparative data
TLDR
Two new non-parametric constructs for the analysis of a broader range of comparative questions are introduced: phylogenetic permutation tests, based on cyclic permutations and permutations conserving phylogenetic signal. Expand
Population thinking and natural selection in dual-inheritance theory
  • W. Houkes
  • Philosophy, Medicine
  • Biology & philosophy
  • 2012
TLDR
A deflationary perspective on theories of cultural evolution, in particular dual-inheritance theory, has recently been proposed by Lewens and identifies a need for further modelling efforts, but also offers scope for enhancing the explanatory power of dual-Inheritance Theory. Expand

Are human beings part of the rest of nature?
Unified explanations seek to situate the traits of human beings in a causal framework that also explains the trait values found in nonhuman species. Disunified explanations claim that the traits ofExpand

Testing the hypothesis of common ancestry.
TLDR
This work reviews and critically examines some arguments that have been proposed in support of the hypothesis that all life on earth traces back to a single common ancestor, and describes some theoretical results that suggest the hypothesis may be intrinsically difficult to test. Expand
Phylogenies and the Comparative Method
TLDR
A method of correcting for the phylogeny has been proposed, which specifies a set of contrasts among species, contrasts that are statistically independent and can be used in regression or correlation studies. Expand
Early fixation of an optimal genetic code.
TLDR
It is shown that if theoretically possible code structures are limited to reflect plausible biological constraints, and amino acid similarity is quantified using empirical data of substitution frequencies, the canonical code is at or very close to a global optimum for error minimization across plausible parameter space.

TLDR
The adaptationist programme is faulted for its failure to distinguish current utility from reasons for origin, and Darwin’s own pluralistic approach to identifying the agents of evolutionary change is supported. Expand
