Revisiting evolutionary rate-time relationships

open access: yesEvolution, 2023
Abstract Rates of molecular, phenotypic, and lineage diversification typically scale negatively with time interval of measurement, raising longstanding questions about time-dependency of evolutionary processes. These patterns and their potential meaning have recently re-entered evolutionary discussions.

Population Genomics Provides Novel Insights Into Evolutionary Relationships and Local Adaptation of Two Ecotypes Coilia nasus [PDF]

open access: yesEcology and Evolution
Coilia nasus is an economically important fish species that exhibits two distinct life history strategies: an anadromous form, which migrates from seawater to freshwater to spawn, and a freshwater‐resident form that completes its entire life cycle in ...

Evolutionary relationships of microbial aromatic prenyltransferases.

open access: yesPLoS ONE, 2011
The linkage of isoprenoid and aromatic moieties, catalyzed by aromatic prenyltransferases (PTases), leads to an impressive diversity of primary and secondary metabolites, including important pharmaceuticals and toxins.

Complete mitochondrial DNA sequence of the Psammocora profundacella (Scleractinia, Psammocoridae): mitogenome characterisation and phylogenetic implications [PDF]

open access: yesBiodiversity Data Journal, 2021
Complete mitochondrial DNA sequence data have played a significant role in phylogenetic and evolutionary studies of scleractinian corals. In this study, the complete mitogenome of Psammocora profundacella Gardiner, 1898, collected from Guangdong Province,

Self-Perceived Attractiveness, Romantic Desirability and Self-Esteem: A Mating Sociometer Perspective [PDF]

open access: yes, 2013
Sociometer theory proposes that self-esteem is an adaptation which evolved to monitor and regulate interpersonal relationships. It is therefore sensitive to self-assessments in domains relevant to relational desirability.

Capturing genetic variation in crop wild relatives: An evolutionary approach [PDF]

open access: yes, 2022
Crop wild relatives (CWRs) offer novel genetic resources for crop improvement. To assist in the urgent need to collect and conserve CWR germplasm, we advance here the concept of an “evolutionary” approach.

Whale ankles and evolutionary relationships [PDF]

open access: yesNature, 1998
There are two main hypotheses for the relationships of the mammalian order Cetacea (comprising whales, dolphins and porpoises). The first hypothesis, mainly supported by DNA sequence data1,2, is that one of the groups of artiodactyls (for example, the hippopotamids) is the closest extant relative of whales and that Artiodactyla are paraphyletic if ...

Evolutionary Relationships and Systematics of the Alphaviruses [PDF]

open access: yesJournal of Virology, 2001
ABSTRACT Partial E1 envelope glycoprotein gene sequences and complete structural polyprotein sequences were used to compare divergence and construct phylogenetic trees for the genus Alphavirus . Tree topologies indicated that the mosquito-borne alphaviruses could have arisen in either the Old or the New ...
