Challenges in homology search: HMMER3 and convergent evolution of coiled-coil regions

Nucleic Acids Research, 2013
Detection of protein homology via sequence similarity has important applications in biology, from protein structure and function prediction to reconstruction of phylogenies. Although current methods for aligning protein sequences are powerful, challenges

Convergent Evolution of Pain-Inducing Defensive Venom Components in Spitting Cobras

Science, 2020
From offense to defense Venom in snakes is largely used to subdue and/or kill prey, and most venoms have clear actions that facilitate death or paralysis.

Demographic History, Adaptation, and NRAP Convergent Evolution at Amino Acid Residue 100 in the World Northernmost Cattle from Siberia

Molecular biology and evolution, 2021
Native cattle breeds represent an important cultural heritage. They are a reservoir of genetic variation useful for properly responding to agriculture needs in the light of ongoing climate changes. Evolutionary processes that occur in response to extreme

Predicting the strength of urban‐rural clines in a Mendelian polymorphism along a latitudinal gradient

Evolution Letters, 2020
Cities are emerging as models for addressing the fundamental question of whether populations evolve in parallel to similar environments. Here, we examine the environmental factors that drive the evolution of parallel urban‐rural clines in a Mendelian ...

Understanding natural selection and similarity: Convergent, parallel and repeated evolution

Molecular Ecology, 2023
Parallel and convergent evolution offer some of the most compelling evidence for the significance of natural selection in evolution, as the emergence of similar adaptive solutions is unlikely to occur by random chance alone.

Propulsive nanomachines: the convergent evolution of archaella, flagella, and cilia.

FEMS Microbiology Reviews, 2020
Echoing the repeated convergent evolution of flight and vision in large eukaryotes, propulsive swimming motility has evolved independently in microbes in each of the three domains of life. Filamentous appendages-archaella in Archaea, flagella in Bacteria,

Convergent evolution of venom gland transcriptomes across Metazoa

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance On more than 100 occasions, animals have independently evolved the ability to produce and deliver potent secretions to subdue prey or predators—venom.

Convergent evolution in toothed whale cochleae

BMC Evolutionary Biology, 2019
Background Odontocetes (toothed whales) are the most species-rich marine mammal lineage. The catalyst for their evolutionary success is echolocation - a form of biological sonar that uses high-frequency sound, produced in the forehead and ultimately ...

Avian phenotypic convergence is subject to low genetic constraints based on genomic evidence

BMC Evolutionary Biology, 2020
Background Phenotypic convergence between distinct species provides an opportunity to examine the predictability of genetic evolution. Unrelated species sharing genetic underpinnings for phenotypic convergence suggests strong genetic constraints, and ...

Testing phylogenetic hypotheses of the subgenera of the freshwater crayfish genus Cambarus (Decapoda: Cambaridae). [PDF]

PLoS ONE, 2012
The genus Cambarus is one of three most species rich crayfish genera in the Northern Hemisphere. The genus has its center of diversity in the Southern Appalachians of the United States and has been divided into 12 subgenera.
