In the meantime, we understand much better how function is encoded in the genome. The current task is now to examine how genetic modifications in molecular systems can promote adaptation in natural populations. Arabidopsis thaliana is a focal system in plant molecular biology. Genes and pathways controlling its development, physiology and immunity have been researched intensively. Its broad latitudinal distribution in Europe makes it a unique system to dissect the molecular underpinnings of adaptation. I will review some of the molecular changes that have been successfully associated with adaptive evolution in A. thaliana. I will thereby illustrate why reconciling molecular and evolutionary biology is a difficult yet necessary task, requiring a shift of concepts in both molecular biology and evolutionary theory. 5 Plenary (Wed 21) POPULATION GENETICS OF HOST-PARASITE COEVOLUTION Dieter Ebert1 1Zoological Institute, University of Basel, Switzerland [email protected] Hosts evolve to minimize the fitness reduction caused by parasites, while parasites optimise the exploitation of their hosts. In models of this process high genetic specificity in host – parasite interactions is assumed. These interactions are in the centre of theory of host – parasite coevolution and determine important aspects of the coevolutionary process, such as its tempo and mode, the occurrence of cyclic allele frequencies, and the potential for evolutionary novelty. They are also crucial for the consequences of coevolution, such as the maintenance of sex and of genetic variation. In my presentation I will analyse the genetic architecture of host-parasite interactions and will test predictions and assumptions of models of host – parasite coevolution. Finally I will match predictions with patterns from long-term coevolution records. 6 Plenary (Thu 22) CANCER THROUGH THE EYE OF EVOLUTIONARY MEDICINE Mel Greaves1 1Division of Molecular Pathology, The Institute of Cancer Research, United Kingdom [email protected] There are two striking examples of somatic cell evolution in humans (and vertebrates in general): the immune system and cancer. In the former, recombinase enzymes target diversification of the immunoglobulin and T cell receptor loci in lymphocytes provides the substrate (>1011 variants) for natural selection by infectious antigenic epitopes. In cancer, stochastic mutational processes drive genetic diversification of clones of cell that under natural selection within complex tissue ecosystems and in response to therapeutic pressure. Starting from a single founder cell, cancer clones evolve over time frames of 1 to 50 years, often in a covert fashion, but the end result is the generation of a robust and weed-like quasi-species of immortal and invasive cells that hijack normal tissue function. In exceptional circumstances, cancer cells transit, parasitic like, individual to individual. Therapy itself inadvertently provides positive selective pressure for the emergence of drug-resistant mutant sub- clones. Whole genome sequencing reveals the extent of genetic, mutational complexity in cancer and when interrogated at the single cell level, it is clear that cancers have tree-like clonal phylogenies with variegated genetics of sub-clones. Within sub-clones, cells with stem cell properties sustain and propel clonal expansion and provide the cellular units of selection. Cancer’s Darwinian character has substantial implications for prevention, prognosis and treatment. 7 Plenary (Fri 23) CHARTING THE GENOTYPE-PHENOTYPE MAP: LESSONS FROM DROSOPHILA Trudy Mackay1 1Department of Genetics, North Carolina State University, United States [email protected] Quantitative traits are affected by multiple interacting loci with individually small and environmentally sensitive effects. Knowledge of the detailed genetic architecture of quantitative traits is important from the perspectives of evolutionary biology, human health and plant and animal breeding. Understanding the genetic architecture of quantitative traits begins with identifying the genes regulating these traits, mapping the subset of genetically varying quantitative trait loci (QTLs) in natural populations, and pinpointing the molecular polymorphisms defining QTL alleles. Drosophila brings an impressive toolkit to the challenge of genetically dissecting quantitative traits. I will discuss insights into the complex genetic architecture of quantitative traits obtained from genome wide association mapping in the Drosophila melanogaster Genetic Reference Panel (DGRP), which consists of 192 sequenced inbred lines derived from the Raleigh, USA population. These studies indicate that epistatic gene action is common, and additivity can be an emergent property of underlying genetic interaction networks. Epistasis causes hidden quantitative genetic variation in natural populations, the potential for rapid speciation, and negatively impacts the predictive ability of additive models. These observations offer valuable lessons for understanding the genetic basis of variation for quantitative traits in other organisms. 8 Plenary (Sat 24) SEX DIFFERENCES IN NATURAL SELECTION ON REPRODUCTIVE SCHEDULING AND LONGEVITY IN HUMANS Virpi Lummaa1 1Department of Animal and Plant Sciences, University of Sheffield, United Kingdom [email protected] Despite senescence with age, most animals retain ability to reproduce until relatively close to death. Humans provide an interesting case because with mid-life menopause, women show a radical de- coupling of senescence in reproductive and somatic systems, leading to up to half of total lifespan spent post-reproductive. By contrast, men maintain reproductive ability until much later ages. Although men thus sire offspring at older ages than women, nearly all contemporary human populations exhibit sexual dimorphism in lifespan with women outliving men by on average of five years. While proximate causes for such fertility and lifespan differences
