Abstract Growth differentiation factor 15 (GDF15) is recently emerging not only as a stress-
related mitokine, but also as a key player in the aging process, being one of the most up …

Despite substantial progress in understanding the genetic basis for differences in
morphology, physiology, and behavior, many phenotypes of interest are difficult to study with …

Deserts are among the harshest environments on Earth. The multiple ages of different
deserts and their global distribution provide a unique opportunity to study repeated …

Between the 1930s and 1950s, scientists developed key principles of population genetics to
try and explain the aging process. Almost a century later, these aging theories, including …

Although lifespan in mammals varies over 100-fold, the precise evolutionary mechanisms
underlying variation in longevity remain unknown. Species-specific genetic changes have …

Dissecting the relationship between gene function and substitution rates is key to
understanding genome-wide patterns of molecular evolution. Biochemical pathways provide …

Ecological flexibility, extended lifespans, and large brains have long intrigued evolutionary
biologists, and comparative genomics offers an efficient and effective tool for generating new …

Simple Summary As a group of organisms, non-avian reptiles, most of which are the~
11,000 species of lizards and snakes, are an extraordinarily diverse group, displaying a …

Telomeres are terminal DNA regions of chromosomes that prevent chromosomal fusion and
degradation during cell division. In cattle, leukocyte telomere length (LTL) is associated with …

Birds and bats have long lifespans relative to their body size compared with non-flying
animals. However, the genomic basis associated with longer lifespan of flying species …
