  Title Genetic parameters of eventing horse competition in France Type Journal Article
  Year 2001 Publication (up) Genetics, Selection, Evolution. : GSE Abbreviated Journal Genet Sel Evol  
  Volume 33 Issue 2 Pages 175-190  
  Keywords Animals; Behavior, Animal; Female; France; Genotype; Horses/*genetics; Male; Physical Conditioning, Animal; Selection (Genetics); *Sports; Stereotyped Behavior  
  Abstract Genetic parameters of eventing horse competitions were estimated. About 13 000 horses, 30 000 annual results during 17 years and 110 000 starts in eventing competitions during 8 years were recorded. The measures of performance were logarithmic transformations of annual earnings, annual earnings per start, and annual earnings per place, and underlying variables responsible for ranks in each competition. Heritabilities were low (0.11 / 0.17 for annual results, 0.07 for ranks). Genetic correlations between criteria were high (greater than 0.90) except between ranks and earnings per place (0.58) or per start (0.67). Genetic correlations between ages (from 5 to 10 years old) were also high (more than 0.85) and allow selection on early performances. The genetic correlation between the results in different levels of competition (high/international and low/amateur) was near 1. Genetic correlations of eventing with other disciplines, which included partial aptitude needed for eventing, were very low for steeplechase races (0.18) and moderate with sport: jumping (0.45), dressage (0.58). The results suggest that selection on jumping performance will lead to some positive correlated response for eventing performance, but much more response could be obtained if a specific breeding objective and selection criteria were developed for eventing.

  Title Species-level selection reduces selfishness through competitive exclusion Type Journal Article
  Year 2007 Publication (up) Journal of Evolutionary Biology Abbreviated Journal  
  Volume 20 Issue 4 Pages 1459-1468  
  Keywords  
  Abstract Abstract Adaptation does not necessarily lead to traits which are optimal for the population. This is because selection is often the strongest at the individual or gene level. The evolution of selfishness can lead to a .tragedy of the commons., where traits such as aggression or social cheating reduce population size and may lead to extinction. This suggests that species-level selection will result whenever species differ in the incentive to be selfish. We explore this idea in a simple model that combines individual-level selection with ecology in two interacting species. Our model is not influenced by kin or trait-group selection. We find that individual selection in combination with competitive exclusion greatly increases the likelihood that selfish species go extinct. A simple example of this would be a vertebrate species that invests heavily into squabbles over breeding sites, which is then excluded by a species that invests more into direct reproduction. A multispecies simulation shows that these extinctions result in communities containing species that are much less selfish. Our results suggest that species-level selection and community dynamics play an important role in regulating the intensity of conflicts in natural populations.

  Title Chimpocentrism: Bias in cognitive ethology Type Journal Article
  Year 1982 Publication (up) Journal of Human Evolution Abbreviated Journal  
  Volume 11 Issue 1 Pages 3-17  
  Keywords herring gull; chimpanzee; cognition; tool-use; shell-dropping; mollusk; predation  
  Abstract Herring gulls drop hard-shelled mollusks and hermit crab-inhabited molluskan prey in order to break the shells and gain access to the edible interior. A field study of predatory shell dropping on Cape Cod, Massachusetts, U.S.A. showed that the gulls usually drop the same shell repeatedly, orient directly to dropping sites that are invisible from the point at which the mollusks are captured, drop preferentially on hard surfaces, adjust dropping heights to suit the area and elasticity of the substrate, orient directly into the wind while dropping, sever the large defensive cheliped of hermit crabs before consumption, and rinse prey that is difficult to swallow. Proficiency in prey dropping is acquired through dropping objects in play, trial-and-error learning, and perhaps, observation learning.

Observable attributes of predatory shell-dropping support inferences that the gulls are capable of extended concentration, purposefulness, mental representation of spatially and temporally displaced environmental features, cognitive mapping, cognitive modeling, selectivity, and strategy formation. Identical cognitive processes have been inferred to underlie the most sophisticated forms of chimpanzee tool-use.

Advanced cognitive capacities are not restricted to chimpanzees and other pongids, and are not associated uniquely with tool use. The chimpocentric bias should be abandoned, and reconstructions of the evolution of intelligence should be modified accordingly.

  Title Mitochondrial DNA sequences of various species of the genus Equus with special reference to the phylogenetic relationship between Przewalskii's wild horse and domestic horse Type Journal Article
  Year 1995 Publication (up) Journal of Molecular Evolution Abbreviated Journal J Mol Evol  
  Volume 41 Issue 2 Pages 180-188  
  Keywords Animals; Base Sequence; Chromosomes; Conserved Sequence/genetics; DNA, Mitochondrial/*genetics; Evolution; Genetic Variation/*genetics; Horses/*genetics; Molecular Sequence Data; *Phylogeny; RNA, Transfer, Pro/genetics; Sequence Alignment; Sequence Analysis, DNA  
  Abstract The noncoding region between tRNAPro and the large conserved sequence block is the most variable region in the mammalian mitochondrial DNA D-loop region. This variable region (ca. 270 bp) of four species of Equus, including Mongolian and Japanese native domestic horses as well as Przewalskii's (or Mongolian) wild horse, were sequenced. These data were compared with our recently published Thoroughbred horse mitochondrial DNA sequences. The evolutionary rate of this region among the four species of Equus was estimated to be 2-4 x 10(-8) per site per year. Phylogenetic trees of Equus species demonstrate that Przewalskii's wild horse is within the genetic variation among the domestic horse. This suggests that the chromosome number change (probably increase) of the Przewalskii's wild horse occurred rather recently.

  Title Lateralization of mother�infant interactions in a diverse range of mammal species Type Journal Article
  Year 2017 Publication (up) Nature Ecology & Evolution Abbreviated Journal Nat Ecol Evol  
  Volume 1 Issue Pages 0030 Ep -  
  Keywords  
  Abstract Left-cradling bias is a distinctive feature of maternal behaviour in humans and great apes, but its evolutionary origin remains unknown. In 11 species of marine and terrestrial mammal, we demonstrate consistent patterns of lateralization in mother�infant interactions, indicating right hemisphere dominance for social processing. In providing clear evidence that lateralized positioning is beneficial in mother�infant interactions, our results illustrate a significant impact of lateralization on individual fitness.
