All organisms produce specialized organic molecules, ranging from small volatile chemicals
to large gene-encoded peptides, that have evolved to provide them with diverse cellular and …

Spider silk is strong and extensible but still biodegradable and well tolerated when
implanted, making it the ultimate biomaterial. Shortcomings that arise in replicating spider …

Spider silks are among the toughest known materials and thus provide models for
renewable, biodegradable, and sustainable biopolymers. However, the entirety of their …

Spiders produce nature's toughest fiber using renewable components at ambient
temperatures and with water as solvent, making it highly interesting to replicate for the …

ABSTRACT Spiders (Order Araneae) are massively abundant generalist arthropod
predators that are found in nearly every ecosystem on the planet and have persisted for over …

Background The duplication of genes can occur through various mechanisms and is thought
to make a major contribution to the evolutionary diversification of organisms. There is …

The marbled crayfish Procambarus virginalis is a unique freshwater crayfish characterized
by very recent speciation and parthenogenetic reproduction. Marbled crayfish also represent …

Spiders are diverse, predatory arthropods that have inhabited Earth for around 400 million
years. They are well known for their complex venom systems that are used to overpower …

High throughput sequencing and phylogenomic analyses focusing on relationships among
spiders have both reinforced and upturned long‐standing hypotheses. Likewise, the …

Fossil age data and molecular sequences are increasingly combined to establish a
timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically …
