The cultural evolution of cultural evolution [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2020 What makes fast, cumulative cultural evolution work? Where did it come from? Why is it the sole preserve of humans? We set out a self-assembly hypothesis: cultural evolution evolved culturally. We present an evolutionary account that shows this hypothesis to be coherent, plausible, and worthy of further investigation. It has the following steps: (0) in

Ancient hybridization fuels rapid cichlid fish adaptive radiations
Nature Communications, 2017 Cichlids underwent a rapid diversification in the Lake Victoria region, expanding to more than 700 species within 150,000 years. Here, Meier and colleagues show that an ancient hybridization between two divergent cichlid lineages generated high genetic ...

Phylogenetic mapping of scale nanostructure diversity in snakes
BMC Evolutionary Biology, 2019 Background Many species of snakes exhibit epidermal surface nanostructures that form complex motifs conferring self-cleaning properties, and sometimes structural iridescence, to their skin.

Threespine Stickleback in Lake Constance: The Ecology and Genomic Substrate of a Recent Invasion
Frontiers in Ecology and Evolution, 2021 Invasive species can be powerful models for studying contemporary evolution in natural environments. As invading organisms often encounter new habitats during colonization, they will experience novel selection pressures.

Sampling environmental DNA from trees and soil to detect cryptic arboreal mammals
Scientific Reports, 2023 Environmental DNA (eDNA) approaches to monitoring biodiversity in terrestrial environments have largely focused on sampling water bodies, potentially limiting the geographic and taxonomic scope of eDNA investigations.

Taxonomic diversity and abundance of enchytraeids (Annelida, Clitellata, Enchytraeida) in the Northern Palaearctic. 1. Asian part [PDF]
Biodiversity Data JournalEnchytraeids, or potworms, are tiny oligochaetes that are distributed worldwide in many terrestrial, freshwater and marine ecosystems. Despite their key role in the functioning of ecosystems, the diversity and abundance of Enchytraeidae are rarely ...

Rapid generation of ecologically relevant behavioral novelty in experimental cichlid hybrids
Ecology and Evolution, 2020 The East African cichlid radiations are characterized by repeated and rapid diversification into many distinct species with different ecological specializations and by a history of hybridization events between nonsister species.

Antimicrobial Resistance and Infection Control, 2020 Background The best strategy to control ESBL-producing Escherichia coli (ESBL-EC) spread in the community is lacking. Methods We developed an individual-based transmission model to evaluate the impact of hand hygiene (HH) improvement and reduction in ...

BMC Biology, 2023 Background Gene duplication events are critical for the evolution of new gene functions. Aristaless is a major regulator of distinct developmental processes. It is most known for its role during appendage development across animals.
