The planarian Schmidtea mediterranea is being studied as a model species for
regeneration, but the assembly of planarian genomes remains challenging. Here, we report …

The ecoevolutionary drivers of species niche expansion or contraction are critical for
biodiversity but challenging to infer. Niche expansion may be promoted by local adaptation …

Hummingbirds share biologically distinctive traits: sustained hovering flight, the smallest bird
body size, and high metabolic rates fueled partially by nectar feeding that provides …

The growth and development of the Longissimus Dorsi muscle are complex, playing an
important role in the determination of pork quality. The study of the Longissimus Dorsi …

AT2 cells harbor alveolar stem cell activity in the lung and can self-renew and differentiate
into AT1 cells during homeostasis and after injury. To identify epigenetic pathways that …

The enzymatic breakdown and regulation of food passage through the vertebrate antral
stomach and pyloric sphincter (antropyloric region) is a trait conserved over 450 million …

The seventh iteration of the reference genome assembly for Rattus norvegicus—mRatBN7.
2—corrects numerous misplaced segments and reduces base-level errors by approximately …

The impact of gene loss on the diversification of taxa and the emergence of evolutionary
innovations remains poorly understood. Here, our investigation on the evolution of the …

Demonstrating the genetic and environmental bases of adaptive phenotypes is a central
goal of biology. Bird colors have a storied tradition at the forefront of conceptual advances in …

Osipova et al. 1 recently identified an inactivating gene mutation that contributed to the
evolution of the hummingbird species by increasing flux of pathways for energy production …
