A total of 458 abstracts were submitted by the October 15, 2020 deadline. Each abstract was subjected to peer-review by two members of the program committee, with reviews completed by December 1, 2021. The committee recommended rejection for less than 1% of the abstracts. Authors of accepted abstracts were notified on January 2, 2021. Two abstracts had been withdrawn by January 27, 2021 The 2020 AAPA abstract issue includes 455 peer-reviewed scientific papers, which will be presented in either video or poster format at the annual meeting. 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 by our partner organizations in some form or another, the Paleopathology Association (PPA), the Human Biology Association (HBA), the American Association for Anthropological Genetics (AAAG), and the Dental Anthropology Association (DAA). Abstracts are presented alphabetically by the last name of the first author. The abstracts illustrate the remarkable breadth of our discipline, covering a range of research topics and approaches, and with global reach and incredible time depth. A total of 8 invited symposia included 82 abstracts. Contributed abstract submissions totaled 373. Broken down by subfield, these include Bioarchaeology (~23.6%), Primatology (~20.6%), Paleoanthropology (~12.9%), Human Biology (~13.9%), Functional Anatomy and Tissue Biology (~10.5%), Genetics and Genomics (~9.9%), Forensics (~7%), and Education in Biological Anthropology (~2.4%). Acknowledgements and Appreciation My sincere thanks to everyone who helped organize the 2021 meetings. We are immensely grateful to the 44 talented, generous, and dedicated members of our Program Committee, who conducted and completed reviews thoughtfully, thoroughly, and expeditiously. We also thank the 23 members of the Program Committee who additionally took on the task of organizing the contributed session in lieu of the advance team who handled this task in prior years. The 2021 annual meeting is unlike no other in AAPA’s history. Many people stepped up to create an entirely new format and keep our scientific community together in the midst of the global pandemic. Thanks are due to our extraordinary business partners, Lori Strong and her team (from Burk & Associates), as well as Ed Hagen (our webmaster and app developer). Our program assistant, Catherine Taylor, has been invaluable, as have the Officers and other members of the Executive Committee.

  • 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.

  • 1 Old World Monkeys
    2003. 5. 23 Dr. Toshio MOURI Old World monkey Although Old World monkey, as a word, corresponds to New World monkey, its taxonomic rank is much lower than that of the New World Monkey. Therefore, it is speculated that the last common ancestor of Old World monkeys is newer compared to that of New World monkeys. While New World monkey is the vernacular name for infraorder Platyrrhini, Old World Monkey is the vernacular name for superfamily Cercopithecoidea (family Cercopithecidae is limited to living species). As a side note, the taxon including Old World Monkey at the same taxonomic level as New World Monkey is infraorder Catarrhini. Catarrhini includes Hominoidea (humans and apes), as well as Cercopithecoidea. Cercopithecoidea comprises the families Victoriapithecidae and Cercopithecidae. Victoriapithecidae is fossil primates from the early to middle Miocene (15-20 Ma; Ma = megannum = 1 million years ago), with known genera Prohylobates and Victoriapithecus. The characteristic that defines the Old World Monkey (as synapomorphy – a derived character shared by two or more groups – defines a monophyletic taxon), is the bilophodonty of the molars, but the development of biphilophodonty in Victoriapithecidae is still imperfect, and crista obliqua is observed in many maxillary molars (as well as primary molars). (Benefit, 1999; Fleagle, 1999) Recently, there is an opinion that Prohylobates should be combined with Victoriapithecus. Living Old World Monkeys are all classified in the family Cercopithecidae. Cercopithecidae comprises the subfamilies Cercopithecinae and Colobinae. Cercopithecinae has a buccal pouch, and Colobinae has a complex, or sacculated, stomach. It is thought that the buccal pouch is an adaptation for quickly putting rare food like fruit into the mouth, and the complex stomach is an adaptation for eating leaves.

  • Evolution of the Hominoid Vertebral Column by Scott
    EVOLUTION OF THE HOMINOID VERTEBRAL COLUMN BY SCOTT A. WILLIAMS DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Anthropology in the Graduate College of the University of Illinois at Urbana-Champaign, 2011 Urbana, Illinois Doctoral Committee: Associate Professor John D. Polk, Co-Chair Assistant Professor Charles C. Roseman, Co-Chair Assistant Professor Laura L. Shackelford Professor Steven R. Leigh Professor Lyle W. Konigsberg ABSTRACT This is a study of the numerical composition of the vertebral column, the central structure of the vertebrate body plan and one that plays an instrumental role in locomotion and posture. Recent models of hominoid vertebral evolution invoke very different roles for homology and homoplasy in the evolution of vertebral formulae in living and extinct hominoids. These processes are fundamental to the emergence of morphological structures and reflect similarity by common descent (homology) or similarity by independent evolution (homoplasy). Although the "short backs," reflecting reduced lumbar regions, of living hominoids have traditionally been interpreted as homologies and shared derived characters (synapomorphies) of the ape and human clade, recent studies of variation in extant hominoid vertebral formulae have challenged this hypothesis. Instead, a "long-back" model, in which primitive, long lumbar regions are retained throughout hominoid evolution and are reduced independently in six lineages of modern hominoids, is proposed. The recently described skeleton of Ardipithecus ramidus is interpreted to support the long-back model. Here, larger samples are collected and placed in a larger phylogenetic context than previous studies. Analyses of over 8,000 mammal specimens, representing all major groups and focusing on anthropoid primates, allow for the reconstruction of ancestral vertebral formulae throughout mammalian evolution and a determination of the uniqueness of hominoid vertebral formulae.

  • Evolution of the Human Pelvis
    COMMENTARY THE ANATOMICAL RECORD 300:789–797 (2017) Evolution of the Human Pelvis 1 2 KAREN R. ROSENBERG * AND JEREMY M. DESILVA 1Department of Anthropology, University of Delaware, Newark, Delaware 2Department of Anthropology, Dartmouth College, Hanover, New Hampshire ABSTRACT No bone in the human postcranial skeleton differs more dramatically from its match in an ape skeleton than the pelvis. Humans have evolved a specialized pelvis, well-adapted for the rigors of bipedal locomotion. Pre- cisely how this happened has been the subject of great interest and con- tention in the paleoanthropological literature. In part, this is because of the fragility of the pelvis and its resulting rarity in the human fossil record. However, new discoveries from Miocene hominoids and Plio- Pleistocene hominins have reenergized debates about human pelvic evolu- tion and shed new light on the competing roles of bipedal locomotion and obstetrics in shaping pelvic anatomy. In this issue, 13 papers address the evolution of the human pelvis. Here, we summarize these new contribu- tions to our understanding of pelvic evolution, and share our own thoughts on the progress the field has made, and the questions that still remain.

The study refines the description of its forelimb bones, which was mostly based on a single partial skeleton. The most distinctive feature of the distal humerus is a large, globular, medially tilted capitulum. The groove between the capitulum and the zona conoidea is quite deep. The medial part of the humeral trochlea is also diagnostic in show- ing a less salient medial border. The medial epicondyle is moderately long and more posteriorly reflected than was previously presumed. The coronoid process of the ulna is quite wide. Its medial portion is dis- tinctly concave. The ulnar shaft is anteroposteriorly deep in its proximal half, slender, straight in frontal view, and weakly anteriorly bowing.
