This year’s meeting promises to be outstanding. Alongside the scientific program featuring over 1200 podium and poster presentations, running from Thursday morning, April 16th through Saturday afternoon, April 18th, there are 18 workshops offered this year (some scheduled for Wednesday April 15th), many AAPA Committee on Diversity (COD) initiatives, and a great line up of exhibitors. Once again, the AAPA will be sponsoring a booth featuring a professional photographer taking free headshots on Friday April 17th. Sign up at the booth in the morning and practice your smile. And, of course, remember to read each day’s events in our meeting program so you don’t miss a thing! As most members are aware, two motions were presented at the Annual Business Meeting in 2019 to formally change the name of the American Association of Physical Anthropologists to the American Association of Biological Anthropologists. These motions will be voted upon for final approval at the 2020 Annual Business meeting on Friday April 17th from 6:30-8:30pm in the Platinum Ballroom. Since our Bylaws stipulate that regular members of the AAPA must be in attendance to cast their vote, I encourage everyone to attend this historic event! Particularly important this year are initiatives that we are taking to recognize and end all forms of harassment and abuse in our field. Towards that end, we have implemented important measures. 1) We have strengthened our Code of Conduct to include actions that the AAPA will take in violation of the Code of Conduct, the AAPA Code of Ethics, and the AAPA Statement on Sexual and other Harassment. 2) We have a confidential reporting website in place, available 24/7: codeofconduct@ burkinc.com. If you find yourself in a dangerous situation, do not hesitate to call 911. For support in other instances, call or text 703-592-9946 at any time during the meeting. This number reaches staff from Burk & Associates (our meeting manage- ment company), who are attending the conference. 3) There will be a Safe Space created behind the registration desk to welcome anyone who feels threatened, unsafe, or wishes to speak with a Safety Ally. 4) A new Harassment Report Committee has been formed whose task is to immedi- ately respond to reports and assist the Executive Committee in taking subsequent actions. AAPA Conference Program 5 MESSAGE FROM THE AAPA PRESIDENT 5) There will be approximately 30 individuals (including Executive Committee members, Burk and Associate personnel, and other AAPA members) trained as Safety Allies at the meeting (they will be identified by wearing a large green Safety Ally button). Each ally is there to assist anyone needing to discuss or report an incident and/or requiring a safe space. 6) We have invited Sherry Marts from S*Marts Consulting, LLC, a leader in working with organizations to create and maintain inclusive and safe professional environments, to train all Safety Allies to recognize and respond to harassment. 7) Lastly, the Presidential Panel this year, held on Thursday April 16th from noon to 2pm in Diamond 4-5, will be a plenary session featuring Sherry Marts who will be talking about Building Community: Recognizing and Resisting Harassment. I hope everyone can attend. Organizing and running our association and annual meeting takes a herculean effort by an extraordinary number of people. Great thanks go to our Vice President, Steve Leigh for completing the unenviable task of coordinating the scientific program, the Program Committee for evaluating over 1200 abstracts, the coordinators and judges of our student and professional awards, the many student volunteers who help at our meeting, Lori Strong, Heide Rohland, and all Burk and Associates folks for helping us maintain our membership and plan our meeting, the over 300 member volunteers who serve on committees throughout the year, and of course, Executive Committee members who work helps ensure that the AAPA remains a vibrant association. Enjoy the Meeting! Anne L. Grauer President American Association of Physical Anthropologists 6 MESSAGE FROM THE VP & PROGRAM CHAIR Welcome! It is my great pleasure to welcome you to the 2020 meeting of the American Association of Physical Anthropologists. This year’s meeting is our 89th, and will be held in Los Angeles, CA. The main conference hotel, the Marriott LA Live, is attached to our main venue, the Los Angeles Convention Center. We are excited to be visiting Los Angeles for the first time in our history. We are grateful to our Local Arrangements Committee, Kristi Lewton (USC) and Stephanie Meredith (West Los Angeles College). We hope that you will enjoy the meeting. Our program includes over 1,200 peer-reviewed scientific papers, which will be presented in either podium or poster sessions beginning Thursday morning. The 70 scientific sessions include 6 invited podium symposia, 18 invited poster symposia, along with contributed podium and poster sessions. In addition, there are 18 innovative and exciting workshop sessions that run in parallel to the scientific program. Once again, our program is truly international, with scientists from all over the world including Africa, Asia, Australia, Europe, Latin America, and the Middle East. We are pleased to be joined in Los Angeles by our partner organizations, the Paleopathology Association (PPA), the Human Biology Association (HBA), the American Association for Anthropological Genetics (AAAG), and the Dental Anthropology Association (DAA). The American Anthropological Association (AAA) is also joining us in sponsoring a session this year. Programming officially begins on Wednesday, April 15, 2020, with the Committee on Diversity Undergraduate Research Symposium (open to everyone from 6:00-8:00 pm) and the Opening Reception (8:00-11:00 pm). This year’s venue is truly an exceptional space and will promote a very productive set of meetings. We’ve grown in size, complexity, and scope of our meetings. As in previous years, podium presentations need to be uploaded onto a central secure server in the Speaker Ready Room no later than a half day before the presentation. This server will then “push” pres- entations to the appropriate meeting room and

Patterns of allometric and size-independent cranial shape variation were subsequently described and related to known papionin phylogenetic relationships and patterns of development. Results confirm that allometric scaling of craniofacial shape characterized by positive facial allometry and negative neurocranial allometry is present across adult papionins. Pairwise comparisons of regression lines among genera revealed considerable homogeneity of scaling within the Papionini, however statistically significant differ- ences in regression lines also were noted.

    Report by the ESA–ESO Working Group on Extra-Solar Planets

    Report by the ESA–ESO Working Group on Extra-Solar Planets 4 March 2005 Summary Various techniques are being used to search for extra-solar planetary signatures, including accurate measurement of radial velocity and positional (astrometric) dis- placements, gravitational microlensing, and photometric transits. Planned space experiments promise a considerable increase in the detections and statistical know- ledge arising especially from transit and astrometric measurements over the years 2005–15, with some hundreds of terrestrial-type planets expected from transit mea- surements, and many thousands of Jupiter-mass planets expected from astrometric measurements. Beyond 2015, very ambitious space (Darwin/TPF) and ground (OWL) experiments are targeting direct detection of nearby Earth-mass planets in the habitable zone and the measurement of their spectral characteristics. Beyond these, ‘Life Finder’ (aiming to produce confirmatory evidence of the presence of life) and ‘Earth Imager’ (some massive interferometric array providing resolved images of a distant Earth) arXiv:astro-ph/0506163v1 8 Jun 2005 appear as distant visions. This report, to ESA and ESO, summarises the direction of exo-planet research that can be expected over the next 10 years or so, identifies the roles of the major facilities of the two organisations in the field, and concludes with some recommendations which may assist development of the field. The report has been compiled by the Working Group members and experts (page iii) over the period June–December 2004. Introduction & Background Following an agreement to cooperate on science planning issues, the executives of the European Southern Observatory (ESO) and the European Space Agency (ESA) Science Programme and representatives of their science advisory structures have met to share information and to identify potential synergies within their future projects.

Tattersall), Springer-Verlag, in press. (1) Evolution of the Primate Brain Dean Falk Department of Anthropology Florida State University Tallahassee, FL 32306-7772 [email protected] (12.) 1 Introduction The mammalian order of primates is known for a variety of species that are lively, curious, social, and intelligent. Nonhuman primates are of special interest to people, not only because they are appealing and entertaining to watch, but also because certain species (e.g., of macaques or baboons) are genetically close to humans, which makes them excellent animal models for medical research. As curious primates ourselves, we wonder about our evolutionary origins. One way to address this topic is to study and compare species from living primates that are thought to approximate broad stages (or grades) that occurred during some 65 million years of primate evolution. Thus, one may compare particular anatomical structures or behaviors across appropriate representatives from the series prosimian-> monkey-> ape -> human. When possible, such a comparative method should be supplemented with the direct method of studying fossil primates, which adds elements of specificity and time to the picture. Within this broader context, we are also interested in the more specific question of how humans came to be, not only the largest-brained primate, but also the most intelligent species on Earth. In order to address this question, one must study primate brain evolution. From our general understanding of primate evolution, we know that certain major adaptations occurred in some groups and that these changed and sculpted evolving brains during many millions of years.

  • Fossil Primates

    Fossil Primates

    AccessScience from McGraw-Hill Education Page 1 of 16 www.accessscience.com Fossil primates Contributed by: Eric Delson Publication year: 2014 Extinct members of the order of mammals to which humans belong. All current classifications divide the living primates into two major groups (suborders): the Strepsirhini or “lower” primates (lemurs, lorises, and bushbabies) and the Haplorhini or “higher” primates [tarsiers and anthropoids (New and Old World monkeys, greater and lesser apes, and humans)]. Some fossil groups (omomyiforms and adapiforms) can be placed with or near these two extant groupings; however, there is contention whether the Plesiadapiformes represent the earliest relatives of primates and are best placed within the order (as here) or outside it. See also: FOSSIL; MAMMALIA; PHYLOGENY; PHYSICAL ANTHROPOLOGY; PRIMATES. Vast evidence suggests that the order Primates is a monophyletic group, that is, the primates have a common genetic origin. Although several peculiarities of the primate bauplan (body plan) appear to be inherited from an inferred common ancestor, it seems that the order as a whole is characterized by showing a variety of parallel adaptations in different groups to a predominantly arboreal lifestyle, including anatomical and behavioral complexes related to improved grasping and manipulative capacities, a variety of locomotor styles, and enlargement of the higher centers of the brain. Among the extant primates, the lower primates more closely resemble forms that evolved relatively early in the history of the order, whereas the higher primates represent a group that evolved more recently (Fig. 1). A classification of the primates, as accepted here, appears above. Early primates The earliest primates are placed in their own semiorder, Plesiadapiformes (as contrasted with the semiorder Euprimates for all living forms), because they have no direct evolutionary links with, and bear few adaptive resemblances to, any group of living primates.
