Analysis of specimens preserved in amber from the Cretaceous period suggests that nematodes changed their host preference towards insects with a complete metamorphosis more recently.

Genomic analysis has shed light on how hadal snailfish have adapted to living at depths of several thousand metres.

Genetic, phenotypic, and evolutionary analysis of a clinical isolate provides an explanation of the intricate genetic factors behind non-carbapenemase carbapenem resistance and sheds light on the evolutionary mechanisms that influence the molecular basis of antibiotic resistance.

Ribosomal proteins Rps27 (eS27) and Rps27l (eS27L) are an ancient pair of duplicated genes that encode functionally interchangeable proteins, yet have been evolutionarily retained because both copies are necessary to achieve protein expression across cell types.

Many published findings about population history that rely on inference of admixture graph models fitted to f-statistics are not robust since the method is generally inappropriate for extracting new information about population history.

Transitions from outcrossing to selfing, a major shift in mating systems, create a specific signature in intra-specific genetic polymorphisms, which can be used to infer the demographic history of populations and acquire valuable insights about the evolution of recombination rates.

Evolution of multiple closely related strains with host-pathogen-like interactions but only one niche and no tradeoffs, can give rise to a spatiotemporally chaotic ecological state that continually diversifies even with generalist mutations that slow the evolution.

After domestication, the cultivation range expansion of crops was not solely dictated by human activity but instead constrained by climatic factors, which in turn resulted in distinct phenotypic characteristics of locally adaptive landraces.
