    Preliminary paleohistological observations of the StW 573 (‘Little Foot’) skull

    Amélie Beaudet, Robert C Atwood ... Dominic Stratford
    Virtual investigation of the 3.67-million-year-old skull of 'Little Foot' using synchrotron radiation reveals histological details of Australopithecus dental and bone tissues.

    New light shed on the early evolution of limb-bone growth plate and bone marrow

    Jordi Estefa, Paul Tafforeau ... Sophie Sanchez
    A three-dimensional investigation of extinct-tetrapod limbs shows that even though bone elongation and blood-cell production are intimately related to mammal long bones, these functions actually appeared successively in tetrapod evolution.

    COVID-19 CG enables SARS-CoV-2 mutation and lineage tracking by locations and dates of interest

    Albert Tian Chen, Kevin Altschuler ... Benjamin E Deverman
    COVID-19 CG is an open source web resource that allows vaccine, therapeutics, and diagnostics developers to track SARS-CoV-2 mutations and lineages by location and time.

    A flagellate-to-amoeboid switch in the closest living relatives of animals

    Thibaut Brunet, Marvin Albert ... Nicole King
    The closest living relatives of animals, the choanoflagellates, switch from a flagellate to an amoeboid phenotype under confinement.

    Adaptive evolution of nontransitive fitness in yeast

    Sean W Buskirk, Alecia B Rokes, Gregory I Lang
    A series of selective events, each improving fitness relative to an immediate predecessor, can result in organisms that are less fit compared to a distant ancestor.

    Experimental Evolution: Failure to progress

    Duncan Greig, Jasmine Ono
    Experiments on yeast cells that are hosts to a killer virus confirm that natural selection can sometimes reduce fitness.

    Whole genome phylogenies reflect the distributions of recombination rates for many bacterial species

    Thomas Sakoparnig, Chris Field, Erik van Nimwegen
    For many bacterial species, recombination dominates genome evolution and phylogenetic patterns that have so far been assumed to reflect clonal relationships, in fact reflect variation in recombination rates across lineages.

    Principles of dengue virus evolvability derived from genotype-fitness maps in human and mosquito cells

    Patrick T Dolan, Shuhei Taguwa ... Judith Frydman
    Distinct selective landscapes in mosquito and human cells shape dengue virus genetic diversity and highlight mechanisms of host adaptation in arboviruses.

    Fitness variation across subtle environmental perturbations reveals local modularity and global pleiotropy of adaptation

    Grant Kinsler, Kerry Geiler-Samerotte, Dmitri A Petrov
    A set of adaptive mutations affect only a small number of phenotypes that matter in the evolution condition, and yet contain substantial latent functional diversity revealed in distant environments.
