Classical Evolution without Evolution

Universe, 2023
The well-known argument of Page and Wootters demonstrates how to “derive" the usual quantum dynamics of a subsystem in a global state which is an eigenstate of the total Hamiltonian. I show how the same argument can be made in classical physics by using a formalism that closely resembles the quantum one.

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.

Modeling the evolution of infrared galaxies: A Parametric backwards evolution model [PDF]

, 2011
We aim at modeling the infrared galaxy evolution in an as simple as possible way and reproduce statistical properties among which the number counts between 15 microns and 1.1 mm, the luminosity functions, and the redshift distributions.

The transcriptome landscape of the carcinogenic treatment response in the blind mole rat: insights into cancer resistance mechanisms

BMC Genomics, 2019
Background Spalax, the blind mole rat, developed an extraordinary cancer resistance during 40 million years of evolution in a subterranean, hypoxic, thus DNA damaging, habitat.

Taxonomic diversity and abundance of enchytraeids (Annelida, Clitellata, Enchytraeida) in the Northern Palaearctic. 1. Asian part [PDF]

Biodiversity Data Journal
Enchytraeids, 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 ...

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.

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.

Evolution is Viral: The Theory of Collective Discontinuous Evolution [PDF]

, 2010
Herein will be discussed the problems associated with the origin of species according to Darwinist processes of individual mutations. We will argue that individual mutations cannot be the driving force of species origination.

'Evolution-Proofing' Antibacterials [PDF]

Evolution, Medicine, and Public Health, 2014
When antibiotics first came into use, they were so effective at curbing bacterial infections that it seemed the age-old battle of man vs. microbe would soon be at an end [1]. Eighty years and dozens of drugs later, we now know better. Following each new antibiotic’s launch, reports soon accumulated that once-treatable infections were becoming ...
