evolutionary biology papers

Evolutionary biology explores the dynamic history of life on Earth, tracing how species change, adapt, and diversify over time. This field investigates the mechanisms driving everything from the development of antibiotic resistance in bacteria to the complex social behaviors of primates, revealing the deep connections that bind all living organisms together.

On Gist.Science, we ensure these groundbreaking discoveries remain accessible by processing every new preprint uploaded to bioRxiv in this category. Our team generates both plain-language overviews and detailed technical summaries for each paper, bridging the gap between raw research and public understanding without requiring a specialized background.

Below are the latest studies in evolutionary biology, offering fresh insights into the ongoing story of life.

Gene-environment interactions govern early regeneration in fir and beech: evidence from participatory provenance trials across Europe

By combining controlled climate-chamber trials with a continental-scale citizen science experiment, this study reveals that while genotype-by-environment interactions drive germination and early development in fir and beech, post-establishment survival is primarily governed by site-level environmental filtering, highlighting a critical life-stage shift in the factors shaping forest regeneration.

Evolutionary rate covariation across malaria parasite species enables inference of protein interactions

This study demonstrates that analyzing evolutionary rate covariation across 22 *Plasmodium* species effectively identifies functionally linked proteins and prioritizes uncharacterized genes, such as PF3D7_0811600, for further experimental validation of their roles in malaria parasite biology.

Emergence and stabilisation of a neo-Y chromosome in nematode species with rare males

This study reveals that Mesorhabditis nematodes have evolved a degenerated neo-Y chromosome that accumulates male-beneficial genes and exhibits a strong fertilization drive, demonstrating that male-specific chromosomes can be maintained and stabilized even in autopseudogamous species where males are rare and genetically useless to offspring.

GLADE: Accurate inference of Gains, Losses, Ancestral genomes, and Duplication Events for comparative genomics

GLADE is a high-accuracy computational tool that reconstructs gene gains, losses, duplications, and ancestral genomes from OrthoFinder data, outperforming existing methods and successfully revealing convergent genomic signatures of dietary specialization in mammals.

Are interphylum spiralian relationships resolvable?

By analyzing two phylogenomic datasets, this study concludes that the evolutionary relationships among the five major spiralian phyla remain unresolved due to an explosive, rapid radiation event at their origin, which has significant implications for interpreting Cambrian fossils and the evolution of key animal traits.

The endoderm cell trajectory of urochordate Styela clava reveals the dual developmental origin and evolution of digestive tract

By employing single-cell RNA sequencing on the urochordate *Styela clava*, this study reveals that the chordate digestive tract originates from two distinct larval endodermal progenitor populations with conserved regulatory programs, suggesting a dual evolutionary origin for stomach and intestinal lineages.

The evolution of genetic drift over 50,000 generations

By analyzing 50,000 generations of the E. coli Long-Term Evolution Experiment, this study demonstrates that the variance in reproductive success driving genetic drift evolves markedly and divergently between replicate populations, thereby altering the probability of beneficial mutations establishing and directly influencing adaptive trajectories.

Bayesian inference of gene flow between sister lineages using genomic data

This paper develops a Bayesian theory to overcome nonstandard statistical challenges in detecting gene flow between sister lineages, demonstrating through simulations and empirical data that this approach offers high power and low false-positive rates for inferring introgression.

Phylogeny and gene function integration uncovers multiple convergences in multicellular and terrestrial transitions

By integrating phylogenomics with functional annotations across 508 species, this study reveals that major evolutionary transitions to multicellularity and terrestrial life are characterized by widespread convergent enrichment of semantically similar biological functions, often achieved through both independent gene family expansions and the recruitment of ancient orthologous genes.

Ancient persistence and newfound diversity of CR1-group retrotransposons across chordates

This study leverages long-read sequencing to provide the first comprehensive chordate-wide analysis of CR1-group retrotransposons, revealing ancient origins, unprecedented diversity, novel elements, and frequent horizontal transfer events that reshape our understanding of their evolutionary history.
