The Annual Evolution Symposium
The American Institute of Biological Sciences (AIBS) and NESCent co-sponsor a symposium on evolution at the annual National Association of Biology Teachers (NABT) conference. The goal of the symposium is to bring applied and current evolutionary science to teachers for use in the classroom. Each year the symposium focuses on a different aspect of evolutionary science, and leading scientists give presentations on their research. Supplemental educational resources are available from each symposium.

The 2008 symposium focused on the benefits of applying evolutionary theory in biological sub-disciplines where evolutionary concepts have not traditionally played a prominent role. The four speakers offered examples of successful evolutionary based research in biochemistry, molecular biology and neurobiology. Resources to help educators bring this message back to their students can be found on the CD. The presentations and additional resources may be found with the speaker bios on this page.

Gene Sharing and Evolution: Surprising Lessons from Lens Crystallins
Among the most discussed mechanisms for change in protein functions are gene duplications, which provide new sources for making altered proteins by mutagenesis. We have developed the concept of “gene sharing” through our studies on lens crystallins. Lens crystallins are abundant water-soluble proteins of the transparent lens responsible for its optical, refractive properties required for focused vision. Gene sharing refers to the fact several functions can share the identical gene. In the case of crystallins, a major increase in the expression of the gene in the lens leads to a new function without loss of the original function. Paradoxically this means that functional specialization and diversification may occur simultaneously. Gene sharing shows that neither gene duplication nor change in protein structure is necessary for functional innovation and evolution. Gene sharing occurs widely and appears to be a fundamental principle of evolution.

Evolutionary Relationships Among Phototrophic Bacteria Deduced from Whole Genome Comparisons
The invention and perfection of photosynthesis is without question one of the true milestones in the evolution of life on Earth. The development of the ability of some photosynthetic organisms to oxidize water to form molecular oxygen changed the redox balance of the Earth and provided the energetic basis for more advanced life to develop. This talk will discuss the complex nonlinear evolutionary path that has led to the modern process of photosynthesis.

Bringing an evolutionary perspective to developmental biology.
The genetic and molecular mechanisms controlling development are the product of evolution and can influence the way in which traits evolve. This talk will discuss the ways in which an appreciation of natural history and evolutionary processes can enhance our understanding of animal development.

Large and complex brains evolved repeatedly
Large and complex brains evolved not just in primates, but also in other taxonomic groups, including octopuses, manta rays, electric fishes, parrots, crows, dolphins, and elephants. Most of these species are highly social. Although the brains of different species share myriad similarities, they also differ in many respects. Dr. Striedter aims to understand how and why those species differences arose. To that end, he asks how the brains of different species diverge in their development. The aim of such questions is to determine what evolutionary changes in the cellular and molecular mechanisms of development underlie the species differences in adult brains.

Evolution Symposium Education Resources Workshop
Friday, Oct. 17
The workshop provided resources and training to support bringing the symposium materials into the classroom. Presenters from Understanding Evolution, BioQUEST, and NESCent offered hands-on introductions to activities that demonstrate applications of evolution. Understanding Evolution staff lead an inquiry investigation in which students follow the steps of scientists Steve Palumbi and Scott Baker, using evolutionary theory and DNA data to investigate whether whales are being illegally hunted and sold as meat in foreign markets. Materials for this activity are available on the CD. BioQUEST and NESCent staff presented "Identifying Biocontrol Agents Through Applied Systematics," which includes information on generating and reading phylogenies.

Biogeography Symposium
Presenters: Joel Cracraft, Kathryn Perez, Frank Fontanella
Biogeography is the study of the patterns and processes of organismal distribution across space and time, and as such is a key discipline within evolutionary biology and ecology. For example, understanding how populations become geographically isolated is fundamental for deciphering the history of species’ origins. The distributions of organisms are also closely linked to climatic and geological history (such as mountain building, continental drift, formation of island arcs), and a goal of biogeographic analysis is to reconstruct those linkages. This symposium brought together a group of professional biologists specializing in biogeography. The presenters provided basic information and examples about the many ways in which biogeography can inform the teaching of biology. Topics included biogeographic principles, mapping distributions using Google Earth and other tools, how the breakup of the supercontinent Gondwana shaped the distribution of today’s organisms, and the biogeography of the Hawaiian islands. Teaching materials and resources were provided.
Co-sponsored by NESCent and the National Center for Science Literacy, Education and Technology, American Museum of Natural History.

EVOLUTION: Applications in Human Health and Populations
December 1, 2007
Atlanta, GA
Understanding how we have been shaped by evolution can help us understand the modern human condition. Evolutionary biology is making important contributions in the field of human health through studies of the human genome, physiology, lifestyle and interaction with the environment. This symposium focused on the emerging field of evolutionary medicine which brings together comparative genomics, epidemiology, anthropology and other fields to synthesize a comprehensive view of human health. Symposium speakers described how this new work is leading to many exciting medical applications. The symposium speakers also discussed ethical issues and more general implications of evolutionary research in society. Symposium presentations are posted here.

MACROEVOLUTION: Evolution above the Species Level
Click here for the web based version of the Macroevolution CD
How do new species and higher taxa originate? How do major innovations, such as sexual reproduction, flowers, and insect, bird, and bat wings, evolve? Basic mechanisms of microevolution (evolutionary change below the species level, among populations and within species) can produce macroevolutionary change (the evolution of novel traits, of species, and of lineages) if given enough time. Macroevolutionary studies explore the evolutionary forces and events that generate the characteristic features of new taxa, the radiations of lineages and their extinctions, and the evolutionary patterns produced by physical processes (e.g., continental drift) on living and extinct organisms.
Presentations in this symposium provided current information about macroevolutionary processes, the distinctions between and the interactions of micro- and macroevolution, the development and evolution of "key innovations" and major lineages of organisms, and the evidence for these processes.

Evolutionary Science and Society: Educating a New Generation
The first symposium, in 2004, focused on evolution education and included a variety of speakers from evolutionary science, education research, and other relevant backgrounds. The four part series consisted of an Introduction to Evolutionary Thinking, The Tree of Life, How Evolution Works, Evolutionary Science: Advancing Societal Well-being. BSCS published "Evolutionary Science and Society: Educating a New Generation" a book of essays by the speakers and information about resources for teaching evolution. A DVD with interviews with various speakers was also produced, and a companion volume of curriculum for teachers was produced.
