Research in cultural evolution has focused on the spread of intuitive or minimally counterintuitive beliefs. However, some very counterintuitive beliefs can also spread successfully, at least in some communities-scientific theories being the most prominent example. We suggest that argumentation could be an important factor in the spread of some very counterintuitive beliefs. A first experiment ...

Quality in its contemporary incarnation is commonly referred to as organizational excellence, enterprise excellence, business excellence, or performance excellence. While technology may serve as a key enabler of enterprise excellence, enterprise excellence itself is in large enabled by the human dimension both in terms of ideation and effort. The human dimension manifests in many ways, with peo...

The target article argues that whole groups can act as interactors in an evolutionary process. We believe that Smaldino's discussion would be advanced by a more thorough analysis of the appropriate replicators and lineages for this model. We show that cultural evolution is necessarily a separate process from cultural group selection, and we also illustrate that the two processes may influence e...

fusion is a developmental anomaly defined as the :union: of two normally separated tooth buds or the partial splitting of one tooth bud into two buds. depending on the stage of development, fusion may be either complete or incomplete. the significance of this particular case was that this fusion occurred in a posterior permanent mandibular tooth, while such a manifestation is more reported in m...

in this study, mutant forms of bacillus thuringiensis spp. israelensis (h14) were produced. these mutants were identified when the cells were cultured on chloramphenicol plates and stained with crystal violet. protoplasts of the mutants were isolated by enzymatic digestion (lysozyme) of the cell walls at the presence of an osmotic stabilizer. the protoplasts were induced to fuse to each other i...
