<jats:p>The neutral models in the Technical Comments depend on the assumption of an initially homogeneous global tropical forest flora. Fossil data and phylogenetic reconstructions instead reveal a high degree of provincialism before the development of modern tropical forests with only occasional long-distance dispersal between continental regions, favoring parallel diversification of a small number of ancestral lineages that dispersed between regions at widely different times.</jats:p>

<jats:p>Ricklefs and Renner (Reports, 27 January 2012, p. 464) suggested that strong correlations in the diversity of shared families between isolated tree assemblages reject neutrality. Simulations of a neutral model indicate, however, that isolated assemblages under various configurations of random speciation and extinction do sustain strong correlations in the diversity of shared families. Thus, reported correlations support rather than reject neutral theory.</jats:p>

<jats:p>Ricklefs and Renner (Reports, 27 January 2012, p. 464) showed correlations of species richness and individual abundance within families across continents and claimed that neutral theory predicts no such correlation. However, they did not substantiate this claim quantitatively with a neutral model. Here, we show that neutral theory can be consistent with these correlations and, consequently, that the correlations alone cannot reject neutrality.</jats:p>

<jats:p>Ricklefs and Renner (Reports, 27 January 2012, p. 464) have argued that the neutral theory of biodiversity and biogeography cannot explain the correlations in family abundances and species richness found between tropical forests from distinct continents. However, we show that such patterns can arise from neutral processes of diversification, migration, and drift over large spatial and temporal scales.</jats:p>

<jats:p>Ricklefs and Renner (Reports, 27 January 2012, p. 464) found significant correlations for abundances and species diversities of families and orders of trees on different continents, which they suggested falsifies the neutral theory of biodiversity (NTB). We argue that the correlations among families and orders and the lack of correlations among genera can be explained by the NTB.</jats:p>

<jats:p>In this account of Bell Labs, Gertner considers how—as an institution and as a collection of personalities—it produced so many technological innovations.</jats:p>
