Examination of Direct and Indirect Effects of Legacy Industrial Pollution On Organ Growth in Wild Yellow Perch (Perca flavescens)
… of pollutants on cell proliferation. I measured relative organ size, trophic position, and hepatic cyp1a1 gene expression in wild yellow perch from impacted and reference sites across the Detroit River and Lake St. Clair. Overall, sites with higher levels of contaminants exhibited increased …

The evolution of neuronal progenitor cell division in mammals: The role of the abnormal spindle-like microcephaly associated (Aspm) protein and epithelial cell polarity
… primates are exceptional for their large brain size relative to body size. Relative brain size, or encephalization, is particularly striking among humans and their direct ancestors. Since the human-chimp split 5 to 7 million years ago, brain size has tripled in the human lineage (Wood …

Endocranial volume and shape variation in early anthropoid evolution
<p>Fossil taxa are crucial to studies of brain evolution, as they allow us to identify evolutionary trends in relative brain size and brain shape that may not otherwise be identifiable in comparative studies using only extant taxa, owing to multiple events of parallel encephalization among primate …

Evolutionary Relationship between Life History and Brain Growth in Anthropoid Primates
… rates are constant across species, and thus body size is determined by mortality rates.</p><p>This project posits that the intrinsic characteristics of species set the pace of life history. Among anthropoids, there is a great deal of variation in growth rates and the pace of life history relative …
