Heart disease is the leading cause of death worldwide. Despite decades of research, most
heart pathologies have limited treatments, and often the only curative approach is heart …

Adaptation to life in caves is often accompanied by dramatically convergent changes across
distantly related taxa, epitomized by the loss or reduction of eyes and pigmentation …

Aggressive behavior is thought to have evolved as a strategy for gaining access to
resources such as territory, food, and potential mates. Across species, secondary sexual …

Laboratory studies have demonstrated that a single phenotype can be produced by many
different genotypes; however, in natural systems, it is frequently found that phenotypic …

Cis-regulatory changes are key drivers of adaptative evolution. However, their contribution
to the metabolic adaptation of organisms is not well understood. Here, we used a unique …

Throughout the evolutionary tree, there are gains and losses of morphological features,
physiological processes, and behavioral patterns. Losses are perhaps nowhere so …

All animals carefully studied sleep, suggesting that sleep as a behavioral state exists in all
animal life. Such evolutionary maintenance of an otherwise vulnerable period of …

Our understanding of cell and developmental biology has been greatly aided by a focus on
a small number of model organisms. However, we are now in an era where techniques to …

Because of diverged adaptative phenotypes, fish species of the genus Xiphophorus have
contributed to a wide range of research for a century. Existing Xiphophorus genome …

The fishing cat, Prionailurus viverrinus, faces a population decline, increasing the
importance of maintaining healthy zoo populations. Unfortunately, zoo-managed individuals …
