  text: The complexity and specificity of movement in vertebrates is driven by a rich
    diversity of spinal motor and interneuron cell types. During development, eleven
    spinal cord progenitor domains generate an equivalent number of cardinal neuron
    types. How progenitor domains, individual progenitors, and post-mitotic diversity
    relate is still unknown. We performed high-resolution, single-progenitor cell
    lineage tracing in the embryonic mouse spinal cord using mosaic analysis with
    double markers (MADM). Our quantitative study of lineage progression revealed
    that spinal cord progenitors undergo highly variable numbers of proliferative,
    neurogenic, and gliogenic cell divisions. The nascent clonally-related neurons
    migrate radially over large distances, span the dorsoventral axis, and even cross
    the midline, demonstrating striking bilaterality. Molecular and morphometric analysis
    indicate high levels of progenitor multipotency, with an individual progenitor
    capable of producing several molecularly and morphologically distinct neuron types,
    as well as astrocytes. These findings redefine spinal cord development as a process
    in which lineage variability — rather than rigid progenitor identity — drives
    the generation of cellular diversity.

  text: As vertebrates transitioned from water to land, locomotion shifted from undulatory
    swimming to limb-based movement. How spinal circuits and their cell types evolved
    to support this transition remains unclear. We leverage frog metamorphosis, which
    recapitulates this transition within a single organism, to define how spinal circuits
    generate aquatic versus terrestrial motor patterns. At swim stages, spinal architecture
    is uniform, with a transcriptionally and anatomically homogeneous motor and interneurons.
    As limbs develop and their movement complexifies, spinal circuits expand in neuron
    number and subtype diversity. This expansion is most pronounced for V1 inhibitory
    neurons, which increase ∼70-fold and diversify into transcriptionally distinct
    subtypes. Disrupting transcription factors defining emerging motor and V1 populations
    reveals molecular segregation between swim and limb circuits, highlighting the
    role of subtype diversity in motor coordination. A multifold increase in inhibitory
    neuron diversity thus underlies the tail-to-limb locomotor transition, providing
    a framework for spinal circuit adaptation during vertebrate evolution.

  text: 'Vertebrates display remarkable diversity of sensorimotor behaviors, each
    adapted to distinct ecological and survival demands. This diversity raises fundamental
    questions about the evolutionary origin of motor control: do conserved spinal
    circuits underlie these behaviors, and how have they diverged across species.
    Recent studies detail spinal cell-type architecture in mammals but comparable,
    high-resolution atlases of the non-mammalian spinal cord are lacking. Here, we
    compare spinal cord cell types between fish, frogs, mice and humans, spanning
    ∼450 million years of evolution. Across species, we define highly conserved programs
    of cell type specification that segregate spinal neurons into nearly identical
    cardinal classes during development. This contrasts with adult stages, when spinal
    cell-type composition selectively diverges for excitatory neuron subpopulations.
    Using spatial transcriptomics, we localize this species divergence to the superficial,
    dorsal spinal cord, where variant neuropeptide expression defines mammalian-specific
    cell types. The most dorsal spinal cord thus emerges as a recently evolved hub
    for sensory integration in mammals, a neospinal cord analogous to the neocortex.</jats:p>'

  text: Amphibians, by virtue of their phylogenetic position, provide invaluable insights
    on nervous system evolution, development, and remodeling. The genetic toolkit
    for amphibians, however, remains limited. Recombinant adeno-associated viral vectors
    (AAVs) are a powerful alternative to transgenesis for labeling and manipulating
    neurons. Although successful in mammals, AAVs have never been shown to transduce
    amphibian cells efficiently. We screened AAVs in three amphibian species—the frogs
    Xenopus laevis and Pelophylax bedriagae and the salamander Pleurodeles waltl—and
    identified at least two AAV serotypes per species that transduce neurons. In developing
    amphibians, AAVs labeled groups of neurons generated at the same time during development.
    In the mature brain, AAVrg retrogradely traced long-range projections. Our study
    introduces AAVs as a tool for amphibian research, establishes a generalizable
    workflow for AAV screening in new species, and expands opportunities for cross-species
    comparisons of nervous system development, function, and evolution.

  text: Vertebrates exhibit a wide range of motor behaviors, ranging from swimming
    to complex limb-based movements. Here we take advantage of frog metamorphosis,
    which captures a swim-to-limb-based movement transformation during the development
    of a single organism, to explore changes in the underlying spinal circuits. We
    find that the tadpole spinal cord contains small and largely homogeneous populations
    of motor neurons (MNs) and V1 interneurons (V1s) at early escape swimming stages.
    These neuronal populations only modestly increase in number and subtype heterogeneity
    with the emergence of free swimming. In contrast, during frog metamorphosis and
    the emergence of limb movement, there is a dramatic expansion of MN and V1 interneuron
    number and transcriptional heterogeneity, culminating in cohorts of neurons that
    exhibit striking molecular similarity to mammalian motor circuits. CRISPR/Cas9-mediated
    gene disruption of the limb MN and V1 determinants FoxP1 and Engrailed-1, respectively,
    results in severe but selective deficits in tail and limb function. Our work thus
    demonstrates that neural diversity scales exponentially with increasing behavioral
    complexity and illustrates striking evolutionary conservation in the molecular
    organization and function of motor circuits across species.

  text: Motor circuits represent the main output of the central nervous system and
    produce dynamic behaviors ranging from relatively simple rhythmic activities like
    swimming in fish and breathing in mammals to highly sophisticated dexterous movements
    in humans. Despite decades of research, the development and function of motor
    circuits remain poorly understood. Breakthroughs in the field recently provided
    new tools and tractable model systems that set the stage to discover the molecular
    mechanisms and circuit logic underlying motor control. Here, we describe recent
    advances from both vertebrate (mouse, frog) and invertebrate (nematode, fruit
    fly) systems on cellular and molecular mechanisms that enable motor circuits to
    develop and function and highlight conserved and divergent mechanisms necessary
    for motor circuit development.

  text: 'Vertebrate movement is orchestrated by spinal inter- and motor neurons that,
    together with sensory and cognitive input, produce dynamic motor behaviors. These
    behaviors vary from the simple undulatory swimming of fish and larval aquatic
    species to the highly coordinated running, reaching and grasping of mice, humans
    and other mammals. This variation raises the fundamental question of how spinal
    circuits have changed in register with motor behavior. In simple, undulatory fish,
    exemplified by the lamprey, two broad classes of interneurons shape motor neuron
    output: ipsilateral-projecting excitatory neurons, and commissural-projecting
    inhibitory neurons. An additional class of ipsilateral inhibitory neurons is required
    to generate escape swim behavior in larval zebrafish and tadpoles. In limbed vertebrates,
    a more complex spinal neuron composition is observed. In this review, we provide
    evidence that movement elaboration correlates with an increase and specialization
    of these three basic interneuron types into molecularly, anatomically, and functionally
    distinct subpopulations. We summarize recent work linking neuron types to movement-pattern
    generation across fish, amphibians, reptiles, birds and mammals.'
