The Dynamics of Molecular Evolution Over 60,000 Generations
Nature, 2017 The outcomes of evolution are determined by a stochastic dynamical process that governs how mutations arise and spread through a population. However, it is difficult to observe these dynamics directly over long periods and across entire genomes.

Scientific Reports, 2021 Biologists have reported on the chemical defences and the phenetic similarity of net-winged beetles (Coleoptera: Lycidae) and their co-mimics. Nevertheless, our knowledge has remained fragmental, and the evolution of mimetic patterns has not been studied

Loss of Plastid Developmental Genes Coincides With a Reversion to Monoplastidy in Hornworts
Frontiers in Plant Science, 2022 The first plastid evolved from an endosymbiotic cyanobacterium in the common ancestor of the Archaeplastida. The transformative steps from cyanobacterium to organelle included the transfer of control over developmental processes, a necessity for the host

Cancer Molecular Evolution [PDF]
Journal of Molecular Evolution, 2015 By far, the majority of studies in molecular evolution have focused on genetic change across one or more generations. Much less is known about the genetic changes that occur during the life time of an individual, or somatic evolution, of which cancer is probably the best-known example.

The evolution of Giant Molecular Filaments [PDF]
, 2017 In recent years there has been a growing interest in studying giant molecular filaments (GMFs), which are extremely elongated (> 100pc in length) giant molecular clouds (GMCs).

DNA Polymerases Engineered by Directed Evolution to Incorporate Nonstandard Nucleotides
Frontiers in Microbiology, 2014 DNA polymerases have evolved for billions of years to accept natural nucleoside triphosphate substrates with high fidelity and to exclude closely related structures, such as the analogous ribonucleoside triphosphates. However, polymerases that can accept

Major Changes in Plastid Protein Import and the Origin of the Chloroplastida
iScience, 2020 Summary: Core components of plastid protein import and the principle of using N-terminal targeting sequences are conserved across the Archaeplastida, but lineage-specific differences exist.

Microorganisms, 2021 It has been demonstrated that the englacial ecosystem in volcanic environments is inhabited by active bacteria. To know whether this result could be extrapolated to other Antarctic glaciers and to study the populations of microeukaryotes in addition to ...

Galaxy chemical evolution models: The role of molecular gas formation [PDF]
, 2017 In our classical grid of multiphase chemical evolution models, star formation in the disc occurs in two steps: first, molecular gas forms, and then stars are created by cloud-cloud collisions or interactions of massive stars with the surrounding ...

Elusive data underlying debate at the prokaryote-eukaryote divide
Biology Direct, 2018 Background The origin of eukaryotic cells was an important transition in evolution. The factors underlying the origin and evolutionary success of the eukaryote lineage are still discussed.
