Abstract

The origins and evolution of the outstanding Neotropical biodiversity are a matter of intense debate. A comprehensive understanding is hindered by the lack of deep-time comparative data across wide phylogenetic and ecological contexts. Here, we quantify the prevailing diversification trajectories and drivers of Neotropical diversification in a sample of 150 phylogenies (12,512 species) of seed plants and tetrapods, and assess their variation across Neotropical regions and taxa. Analyses indicate that Neotropical diversity has mostly expanded through time (70% of the clades), while scenarios of saturated and declining diversity account for 21% and 9% of Neotropical diversity, respectively. Five biogeographic areas are identified as distinctive units of long-term Neotropical evolution, including Pan-Amazonia, the Dry Diagonal, and Bahama-Antilles. Diversification dynamics do not differ across these areas, suggesting no geographic structure in long-term Neotropical diversification. In contrast, diversification dynamics differ across taxa: plant diversity mostly expanded through time (88%), while a substantial fraction (43%) of tetrapod diversity accumulated at a slower pace or declined toward the present. These opposite evolutionary patterns may reflect different capacities for plants and tetrapods to cope with past climate changes.

    We have focused on the mushroom bodies (MB) of Drosophila to determine how the larval circuits are formed and then transformed into those of the adult at metamorphosis. The adult MB has a core of thousands of Kenyon neurons; axons of the early-born g class form a medial lobe and those from later-born a'b' and ab classes form both medial and vertical lobes. The larva, however, hatches with only g neurons and forms a vertical lobe 'facsimile' using larval-specific axon branches from its g neurons. Computations by the MB involves MB input (MBINs) and output (MBONs) neurons that divide the lobes into discrete compartments. The larva has 10 such compartments while the adult MB has 16. We determined the fates of 28 of the 32 types of MBONs and MBINs that define the 10 larval compartments. Seven larval compartments are eventually incorporated into the adult MB; four of their larval MBINs die, while 12 MBINs/MBONs continue into the adult MB although with some compartment shifting. The remaining three larval compartments are larval specific, and their MBIN/MBONs trans-differentiate at metamorphosis, leaving the MB and joining other adult brain circuits. With the loss of the larval vertical lobe facsimile, the adult vertical lobes, are made de novo at metamorphosis, and their MBONs/MBINs are recruited from the pool of adult-specific cells. The combination of cell death, compartment shifting, trans-differentiation, and recruitment of new neurons result in no larval MBIN-MBON connections persisting through metamorphosis. At this simple level, then, we find no anatomical substrate for a memory trace persisting from larva to adult. For the neurons that trans-differentiate, our data suggest that their adult phenotypes are in line with their evolutionarily ancestral roles while their larval phenotypes are derived adaptations for the larval stage. These cells arise primarily within lineages that also produce permanent MBINs and MBONs, suggesting that larval specifying factors may allow information related to birth-order or sibling identity to be interpreted in a modified manner in these neurons to cause them to adopt a modified, larval phenotype. The loss of such factors at metamorphosis, though, would then allow these cells to adopt their ancestral phenotype in the adult system.

    Causal loss-of-function (LOF) variants for Mendelian and severe complex diseases are enriched in 'mutation intolerant' genes. We show how such observations can be interpreted in light of a model of mutation-selection balance, and use the model to relate the pathogenic consequences of LOF mutations at present-day to their evolutionary fitness effects. To this end, we first infer posterior distributions for the fitness costs of LOF mutations in 17,318 autosomal and 679 X-linked genes from exome sequences in 56,855 individuals. Estimated fitness costs for the loss of a gene copy are typically above 1%; they tend to be largest for X-linked genes, whether or not they have a Y homolog, followed by autosomal genes and genes in the pseudoautosomal region. We then compare inferred fitness effects for all possible de novo LOF mutations to those of de novo mutations identified in individuals diagnosed with one of six severe, complex diseases or developmental disorders. Probands carry an excess of mutations with estimated fitness effects above 10%; as we show by simulation, when sampled in the population, such highly deleterious mutations are typically only a couple of generations old. Moreover, the proportion of highly deleterious mutations carried by probands reflects the typical age of onset of the disease. The study design also has a discernible influence: a greater proportion of highly deleterious mutations is detected in pedigree than case-control studies, and for autism, in simplex than multiplex families and in female versus male probands. Thus, anchoring observations in human genetics to a population genetic model allows us to learn about the fitness effects of mutations identified by different mapping strategies and for different traits.
