Evolution is traditionally associated with a process of increasing complexity and gaining new genes. However, the explosion of the genomic era shows that gene loss and simplification is a much more ...

The ability to tolerate toxic substances can help animals find new food sources and thrive in certain ecological niches. Researchers at the Max Planck Institute for Chemical Ecology in Jena have now ...

Animals from completely different branches of the tree of life, such as insects, worms and vertebrates, independently evolved similar genetic solutions to survive on land, according to a new study ...

UW researchers ply the waters of an alpine lake in the Stough Basin of Wyoming’s Wind River Mountains as part of their research into the impacts of trout stocking in the once-fishless lakes. Among ...

Many patients with metastatic cancers receive therapy that is initially highly effective, often resulting in complete remission. However, cancer cells have a remarkable capacity to evolve resistance ...

Many scarab beetles produce rigid projections from the body called horns. The exaggerated sizes of these structures and the staggering diversity of their forms have impressed biologists for centuries.

Humans are fundamentally technological creatures. We depend on the manufacture and use of tools for our survival to a degree qualitatively greater than any other species. Therefore, an understanding ...

This volume is based on the Arthur M. Sackler Colloquium of the National Academy of Sciences, “In the Light of Evolution I: Adaptation and Complex Design,” held December 1-2, 2006, at the Arnold and ...
