Choreography of silk spinning by webspinners (Insecta: Embioptera) reflects lifestyle and hints at phylogeny [PDF]

open access: yes, 2016
Silk spinning defines the morphologically constrained embiopterans. All individuals spin for protection, including immatures, adult males and the wingless females. Enlarged front tarsi are packed with silk glands and clothed with ejectors.

Assumption 0 analysis: comparative phylogenetic studies in the age of complexity [PDF]

open access: yes, 2008
Darwin's panoramic view of biology encompassed two metaphors: the phylogenetic tree, pointing to relatively linear (and divergent) complexity, and the tangled bank, pointing to reticulated (and convergent) complexity.

W(h)ither Fossils? Studying Morphological Character Evolution in the Age of Molecular Sequences [PDF]

open access: yes, 2008
A major challenge in the post-genomics era will be to integrate molecular sequence data from extant organisms with morphological data from fossil and extant taxa into a single, coherent picture of phylogenetic relationships; only then will these ...

Open Reading Frame Phylogenetic Analysis on the Cloud

open access: yesInternational Journal of Genomics, 2013
Phylogenetic analysis has become essential in researching the evolutionary relationships between viruses. These relationships are depicted on phylogenetic trees, in which viruses are grouped based on sequence similarity.
