Evolution from unicellular organisms to larger multicellular ones requires matching their needs
to the rate of exchange of molecular nutrients with the environment. This logistic problem …

The fitness of an evolutionary individual can be understood in terms of its two basic
components: survival and reproduction. As embodied in current theory, trade-offs between these …

Benefits, costs, and requirements accompany the transition from motile totipotent unicellular
organisms to multicellular organisms having cells specialized into reproductive (germ) and …

mRNA localization serves key functions in localized protein production, making it critical that
the translation machinery itself is present at these locations. Here we show that translation …

During the unicellular‐multicellular transition, there are opportunities and costs associated
with larger size. We argue that germ‐soma separation evolved to counteract the increasing …

The immunopathology of chronic obstructive pulmonary disease (COPD) is based on the
innate and adaptive inflammatory immune responses to the chronic inhalation of cigarette …

The presence of salmonellae in fecal samples or cloacal swabs of 97 pet reptiles (15 snakes,
