    Side-blotched lizards (Uta stansburiana) play a biological rock-paper-scissors game in which three differently colored male morphs utilize alternative mating strategies. We identified the genetic basis of this polymorphism, which was previously posited to arise from three alleles at one locus. Orange usurper and blue mate-guarder morphs are associated with two divergent haplotypes in the regulatory region of the sepiapterin reductase gene, but yellow sneaker morphs appear to arise through phenotypic plasticity from the same genetic background as blue morphs. Our simulations show that rock-paper-scissors dynamics can better maintain a polymorphism with a genetic system of two alleles plus plasticity than with a three-allele system. This form of balancing selection that combines genetic determination with phenotypic plasticity expands the possibilities for how stable polymorphisms arise in nature.

    The ruminants are one of the most successful mammalian lineages, exhibiting morphological and habitat diversity and containing several key livestock species. To better understand their evolution, we generated and analyzed de novo assembled genomes of 44 ruminant species, representing all six Ruminantia families. We used these genomes to create a time-calibrated phylogeny to resolve topological controversies, overcoming the challenges of incomplete lineage sorting. Population dynamic analyses show that population declines commenced between 100,000 and 50,000 years ago, which is concomitant with expansion in human populations. We also reveal genes and regulatory elements that possibly contribute to the evolution of the digestive system, cranial appendages, immune system, metabolism, body size, cursorial locomotion, and dentition of the ruminants.
