SUMMARY:Fiona Cowie - Language Genes\, Language Organs and Language Evolution
DESCRIPTION:Fiona Cowie: California Institute of Technology Division of the Humanities and Social SciencesThe recent identification of the so-called ‘grammar gene\,’ FOXP2\, as well as recent advances in our understanding of the numerous psychological mechanisms involved in language acquisition\, raise a number of conceptual and empirical issues that are vital to our understanding of language evolution. In what sense\, if any\, can a gene like FOXP2 be called a ‘gene for language’? In what sense\, if any\, can a congeries of multi-functional psychological mechanisms be called a ‘language organ’? In light of our answers to these questions\, how are we to conceive the role of biological evolution in the evolution of language?

SUMMARY:Francis Steen - The role of consciousness in learning from simulations
DESCRIPTION:Francis Steen: UCLA Department of Communication StudiesI argued in Steen & Owens (2001) that play is a behavioral and cognitive simulation whose biological function is learning. In this presentation\, I address the question of how such learning takes place\, focusing on the role of consciousness. I present some preliminary data from an experiment on strategy-learning in a solitaire game\, and a cognitive model of the large-scale architecture of the mind required to support learning from simulations.http://cogweb.ucla.edu/crp/Papers/Steen_Paradox.html

SUMMARY:William Rice - Reproductive interactions between the sexes: arms-race or mutualistic coevolution?
DESCRIPTION:William Rice: UCSB Department of Ecology\, Evolution & Marine BiologyThe empirical foundation for sexual conflict theory is the unequivocal data from many different taxa demonstrating that females are harmed while interacting with males. But the interpretation of this keystone evidence has been challenged because females may more than compensate the direct costs of interacting with males by the indirect benefits of obtaining higher quality genes for their offspring. A quantification of this trade-off is critical to resolve the controversy. Here I present results from 3 experiments that show that\, at least in the D. melanogaster model system\, indirect benefits do not off-set direct harm to females due to their interactions with males. I also present evidence\, using hemiclonal analysis\, that an ongoing arms race between the sexes can be directly measured in this model system.

SUMMARY:Michael Sockol - Investigating the Origins of Hominid Bipedalism
DESCRIPTION:Michael Sockol: UC Davis Department of Anthropology The origin of the human family\, Hominidae\, has been a primary focus of paleoanthropologists for more than a century. Indeed\, the desire to understand our origins is ubiquitous in human society. Of continuing interest to anthropologists is the nature of the shift to bipedal locomotion in our earliest hominid ancestors. Though debate exists about whether bipedalism serves to define Hominidae\, it is clear that becoming bipedal was the critical first step in the emergence of the human form\, preceding all other major morphological adaptations. Yet\, while the end result is apparent in the fossil record\, the process by which bipedalism arose is unclear. Numerous hypotheses have been proposed for the shift to bipedal locomotion. Many have been discarded while others have withstood the test of time. One such hypothesis\, commonly referred to as the “energetics hypothesis”\, posits an energy savings associated with bipedalism in an ecological context. I review the current state of our knowledge of the shift to bipedal locomotion in early hominids and give reasons for considering the energetics hypothesis as crucial to understanding that shift.
