Phylodynamic pattern of genetic clusters, paradigm shift on spatio-temporal distribution of clades, and impact of spike glycoprotein mutations of SARS-CoV-2 isolates from India

Journal of Global Infectious Diseases, 2021
Introduction: The COVID-19 pandemic is associated with high morbidity and mortality, with the emergence of numerous variants. The dynamics of SARS-CoV-2 with respect to clade distribution is uneven, unpredictable and fast changing.

Homoplasy and Clade Support [PDF]

Systematic Biology, 2009
Distinguishing phylogenetic signal from homoplasy (shared similarities among taxa that do not arise by common ancestry) is an implicit goal of any phylogenetic study. Large amounts of homoplasy can interfere with accurate tree inference, and it is expected that common measures of clade support, including bootstrap proportions and Bayesian posterior ...

Making the most of clade selection [PDF]

, 2017
Clade selection is unpopular with philosophers who otherwise accept multilevel selection theory. Clades cannot reproduce, and reproduction is widely thought necessary for evolution by natural selection, especially of complex adaptations.

Distribution and functional analyses of mutations in spike protein and phylogenic diversity of SARS-CoV-2 variants emerged during the year 2021 in India

Journal of Global Infectious Diseases, 2023
Introduction: Prolonged COVID-19 pandemic accelerates the emergence and transmissibility of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants through the accumulation of adaptive mutations.

The Avian Acetabulum: Small Structure, but Rich with Illumination and Questions

Diversity, 2023
The idea that birds are maniraptoran theropod dinosaurs is now considered an evolutionary consensus. An “open” (i.e., completely or substantially perforate) acetabulum is considered an important synapomorphy verifying the bird–dinosaur nexus.
