Emergence and Fixing of Antiviral Resistance in Influenza A Via Recombination and Hitch Hiking
The dramatic rise of oseltamivir resistance in the H1N1 serotype in the 2007/2008 season and the fixing of H274Y in the 2008/2009 season has raised concerns regarding individuals at risk for season…

Inverse relationship between genetic diversity and epigenetic complexity
Early studies of molecular evolution revealed a correlation between genetic distance and time of species divergence. This observation provoked the molecular clock hypothesis and in turn the ‘Neutr…

Social Processing of Discrete Emotions in Humans
I asked human observers to rate capacity and trustworthiness trait impressions of, and to indicate affiliative and avoidant dispositions, and felt emotive responses toward social objects. I show th…

Evidence of existence of totally different types of ribosomes in intermediate animals
In all organisms, messenger-directed protein synthesis is catalyzed by ribonucleoprotein particles called ribosomes. A ribosome is typically composed of one small and one large subunit which contai…

The genetic equidistance result of molecular evolution is independent of mutation rates
The well-established genetic equidistance result shows that sister species are approximately equidistant to a simpler outgroup as measured by DNA or protein dissimilarity. The equidistance result …

Deciphering the phylogenetic history of neuroserpin orthologs across metazoans by analysis of synteny and rare genomic characters
The superfamily of serine proteinase inhibitors (serpins) is involved in wide arrays of fundamental biological processes such as blood coagulation, complement activation, fibrinolysis, angiogenesis…

Hexose-6-phosphate dehydrogenase modulates the effect of inhibitors and alternative substrates of 11β-hydroxysteroid dehydrogenase 1
Intracellular glucocorticoid reactivation is catalyzed by 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1), which functions predominantly as a reductase in cells expressing hexose-6-phosphat…

Facial Expression Processing Varies with Political Affiliation
Conservative political beliefs have been linked to heightened stress reactivity and protective cognitive biases. Using a facial discrimination task designed to measure perceptions of threat (vs. no…

New species from the deep Pacific suggest that carnivorous sponges date back to the Early Jurassic
Some deep-sea poecilosclerid sponges (Porifera) have developed a carnivorous feeding habit that is very surprising in sponges1. As shown by the typical morphology of their spicules, they most pro…

Using Trees: Myrmecocystus Phylogeny and Character Evolution and New Methods for Investigating Trait Evolution and Species Delimitation (PhD Dissertation)
1) Rates of phenotypic evolution have changed throughout the history of life, producing variation in levels of morphological, functional, and ecological diversity among groups. Testing for the pres…
