<jats:p>Will a podcast about climate change reach the audiences that need to hear it most?</jats:p>

<jats:p>The cerebrum of large mammals is convoluted, whereas that of small mammals is smooth. Mota and Herculano-Houzel (Reports, 3 July 2015, p. 74) inspired a model on an old theory that proposed a fractal geometry. I show that their model reduces to the product of gray-matter proportion times the folding index. This proportional relation describes the available data even better than the fractal model.</jats:p>

<jats:p>Mota and Herculano-Houzel (Reports, 3 July 2015, p. 74) assign power functions to neuroanatomical data and present a model to account for evolutionary patterns of cortical folding in the mammalian brain. We detail how the model assumptions are in conflict with experimental and observational work and show that the model itself does not accurately fit the data.</jats:p>

<jats:p> Davison <jats:italic>et al</jats:italic> . (Reports, 28 August 2015, p. 970) claim that virtual taxa of Glomeromycota show little endemism and that endemism that exists is similar to the levels seen in plant families. We show that this is likely due to the conservative species definition rather than to any ecological pattern. </jats:p>

<jats:p>Bruns and Taylor argue that our finding of widespread distribution among Glomeromycota “virtual taxa” is undermined by the species definition applied. Although identifying appropriate species concepts and accessing taxonomically informative traits are challenges for microorganism biogeography, the virtual taxa represent a pragmatic classification that corresponds approximately to the species rank of classical Glomeromycota taxonomy, yet is applicable to environmental DNA.</jats:p>

<jats:p> De Lussanet claims that our model that accounts for the degree of folding of the cerebral cortex based on the product of cortical surface area and the square root of cortical thickness is better reduced to the product of gray-matter proportion and folding index. Lewitus <jats:italic>et al</jats:italic> ., in turn, claim that the assumptions of our model are in conflict with experimental data; that the model does not accurately fit the data; and that the ancestral mammalian brain was gyrencephalic. Here, we show that both claims are inappropriate. </jats:p>
