Elaboration of B Gene Function to Include the Identity of Novel Floral Organs in the Lower Eudicot Aquilegia (Ranunculaceae)
(American Society of Plant Biologists, 2007)The basal eudicot Aquilegia (columbine) has an unusual floral structure that includes two morphologically distinct whorls of petaloid organs and a clearly differentiated fifth organ type, the staminodium. In this study, ... -
A Morphometrics-Based Phylogeny of the Temperate Gondwanan Mite Harvestmen (Opiliones, Cyphophthalmi, Pettalidae)
(Wiley-Blackwell, 2010)A phylogenetic estimation of the temperate Gondwanan mite harvestman family Pettalidae (Arachnida, Opiliones, Cyphophthalmi) was conducted using 143 morphological variables (59 raw and 84 scaled measurements) from 37 ingroup ... -
The Role of Developmental Genetics in Understanding Homology and Morphological Evolution in Plants
(University of Chicago Press, 2007)Homology assessments are critical to comparative biological studies. Although gene expression data have been proposed as instrumental for defining homologous relationships, several lines of evidence suggest that this type ... -
Sameness, novelty, and nominal kinds
(Springer Science + Business Media, 2014)Organisms and their genomes are mosaics of features of different evolutionary age. Older features are maintained by ‘negative’ election and comprise part of the selective environment that has shaped the evolution of newer ...
