INTRODUCTION frontiers of evolutionary research in the coming Support for ecological and evolutionary research decade. As a result, the themes for future at the National Science Foundation expanded research outlined here reflect both new questions substantially during the past decade. To help and new conceptual frameworks, as well as the guide this expansion, in October 1998 the application of new tools to classic questions in program at NSF hosted a . workshop on “Frontiers in Population Biology”. The workshop had four specific goals: The report from that workshop identified and 1) To identify emerging tools essential to illustrated seven research themes of special evolutionary research; interest in population biology, and described how 2) To identify and illustrate research these themes connect to genetics/ on themes of particular promise; the one hand and to environmental issues on the 3) To summarize major institutional other. The report has been valuable to officers at resources available to support NSF in shaping their programs and balancing evolutionary research; their grant portfolios. 4) To suggest infrastructural needs and Our understanding of evolutionary biology opportunities for enabling the next has advanced enormously in the past six years. generation of advances in our understanding The explosion of genomic information, rapid of evolution. advances in computer and sensor technology, and the development of sophisticated new statistical and analytical approaches coupled with the EMERGING TOOLS recent reorganization of programs at NSF make Many research frontiers identified in this report this an appropriate time to evaluate progress and are now accessible only because of recent, to identify areas in which new investment is explosive advances in technology, while others warranted. In January 2005 a panel of experts lie at the fringe of current technology. A shared met at NSF to identify areas that represent the feature of many of these advances is the scale at frontiers for evolutionary research in the coming which they are conducted. We can now sequence decade. The scope of this workshop was whole genomes, analyze expression of all genes, somewhat larger than that considered at the 1998 and analyze data with desktop supercomputers. It workshop, reflecting the range of evolutionary is clear that advances in phenotypic analysis research and topics considered by Population and equivalent to those on the genomic and Evolutionary Processes, Ecological and computational side are needed, as these research Evolutionary , Animal and frontiers require a variety of high-throughput, related programs at NSF. In addition to high-precision techniques for measurement of identifying nine thematic areas within genetic, physiological, and phenotypic evolutionary biology, the panel considered how characteristics in large numbers of individuals in questions within these areas relate to questions in the field as well as in controlled, laboratory and genomics, , environments. environmental sciences and other areas. • Genomics – The advent of high throughput In reflecting on research frontiers that have DNA sequencing has led to the availability emerged since 1998, two related are of whole genome sequences for a broad evident. First, evolutionary approaches and phylogenetic sample of , including perspectives are increasingly an integral part of replicate genome sequences for different all areas of biological research, from molecular individuals of the same species.

As a result, we are analyses of gene expression (and similar increasingly able to explore the mechanisms, methods) allow dissection of complex processes and patterns of evolutionary change at genetic networks involved in physiological, multiple levels of biological organization from developmental, and behavioral responses. the gene to the .
