(RHOI-supported) Per F. Bibi: The RHOI Bovid Analytical
Working Group met for a conference in Addis Ababa from 4-8
August, 2008. Conference participants included Elisabeth Vrba,
Alan Gentry, Denis Geraads, Maia Bukhsianidze, Dimitris Kostopoulos,
and Faysal Bibi. In the mornings, attendees met at the Hilton
Addis conference facilities to present and discuss topics
relevant to the evolution of Bovidae. Attendees presented
on new Mio-Pliocene specimens from Eurasia and Africa and
focused on the question of the origin of the living bovid
tribes during the late Miocene and their subsequent evolution
during the Pliocene. Afternoons saw the group convening at
the National Museum of Ethiopia to discuss and exchange observations
on fossils from the Middle Awash and Omo collections. A summary
paper of the conference's conclusions is in preparation.

The Carnivore Analytical Working Group met over two days in
late May, 2008, at the University of Poitiers, France. Convened
by Louis de Bonis, the meeting was conducted in a presentation/discussion
format, with research topics spanning the late-middle Miocene
to early Pleistocene.
contextual research by Morales and Pickford, on the middle
Miocene carnivores from Muruyur Formation at Kipsaraman, was
presented. This material adds much needed information to link,
for example, early Miocene Amphicyonids with late Miocene
exciting research included late Miocene feliforms from Toros-Menalla,
Chad (Peigne et al.), the As Sahabi carnivore guild (Rook
and Sardella), small hyaenids from Lothagam (Semenov), a comparison
of the late Miocene European and African carnivoran assemblages
(Koufos and de Bonis), Middle Awash carnivores (Haile-Selassie),
carnivores from Kossom Bougoudi, Chad (Peigne et al.), late
Pliocene carnivores from Ahl al Oughlam, Morocco (Geraads),
Plio-Pleistocene carnivores from South Africa (Hartstone-Rose),
early Pleistocene Megantereon from Italy (Sardella), the evolution
of African carnivores (Lewis), new canids from Aramis, Middle
Awash, Ethiopia (Garcia), and the geographic patterning of
African carnivore faunas (Werdelin).
(RHOI-Supported) The Hominoid Analytical Working Group met March
27-29, 2008 in Thessaloniki, Greece. Organized by Jay Kelley and
George Koufos and hosted by Professor Koufos and the Aristotle
University of Thessalonki, the meeting topic was, "Late Miocene
Euro-African hominoids and their relationships." Further details

The Comparative Behavior and Ecology AWG met at Toro Semliki, Uganda
from July 1-7, 2006. Four members (Hunt, Marchant, McGrew, Moore)
were in attendance (the other two members, Foley and Stanford, were
unable to attend). The group was hosted at the Chimpanzee Research
Camp by its director, Kevin Hunt, and joined by two Ph.D. students,
Alex Piel (UC-San Diego) and Gil Rmos (Indiana).
at Toros Semliki focuses on the ecology and ethology of a wide-ranging
community of partly habituated Pan troglodytes schweinfurthii. Each
day included walking excursions to various areas that represent
the ecological diversity of the site. When not in the bush, formal
discussions were held in the late afternoons, and informal talk
of related topics was constant from dawn until after dark, stimulated
by the day’s events. Chimpanzees called often and were seen
or tracked daily. Also, AWG members collected specimens of social
insects, snails, soils, and associated GPS data.
focused on planning future AWG activities and meetings. It was decided
to organize a Wenner-Gren-style conference on the theme of ‘Primatology
meets Paleoanthropology’, as a climax to the AWG’s activities.
This likely will be held in late 2007, or early 2008, probably in

In August 2005, the Hippopotamid and Anthracotheriid Analytical
Working Group (Jean-Renaud Boisserie, Denis Geraads, Andossa Likius,
and Nikos Solounias) held its first meeting at the National Museums
of Kenya in Nairobi. All four participants attended, in what was
probably the largest group of African fossil hippo and anthracothere
specialists ever gathered in the same room. The current status of
fossil hippo and anthracothere studies was evaluated, and the need
to explore some critical questions in the near future was emphasized,
including the still unclear relationships between the two families,
and the environmental factors that favored the apparently sudden
emergence and spread of various hippo genera during the upper Miocene.
The participants also developed common standards to be used for
anatomical descriptions and morphometrical analyses of these mammals.
Finally, discussions focused on the earliest hippopotamids, greatly
benefiting from the access kindly provided by the National Museums
of Kenya to their paleontological collections.
first workshop of the Phytolith Analytical Working Group, entitled
"Phytoliths in the context of RHOI," was held in May 2005
in CEREGE, Aix-en-Provence, France. Over two days, the participants
examined the key issues related to the study of phytoliths at Aramis
in the Middle Awash Valley, Ethiopia, the advantages, disadvantages,
and similarities of various approaches to analyzing and interpreting
phytolith data, and the progress to date on phytolith research and
its limitations for the characterization of the environment of early
hominids in east Africa. This meeting gave the Phytolith AWG the
opportunity to prioritize the scientific themes concerning phytolith
research in the context of RHOI, and to devise approaches and field
work strategies that would allow an assessment of the precision
and accuracy of phytolith-based environmental studies.
Comparative Behavior and Ecology Analytical Working Group met 11-13
March 2005, hosted by the Department of Anthropology, Miami University,
in Oxford, Ohio. The six AWG members (Robert Foley, Kevin Hunt,
Linda Marchant, William McGrew, James Moore, and Craig Stanford),
most of whom study the behavioral ecology of living apes, met with
six counterpart palaeoanthropological colleagues, Bruce Latimer,
Owen Lovejoy, Travis Pickering, Kathy Schick, Nick Toth, and Thomas
Wynn. The meeting was done in informal, workshop-style, around a
single table, and focussed on the following themes of Primatology
Meets Palaeoanthropology: How can field primatologists frame questions
that yield answers of interest and use to palaeoanthropologists
in their reconstruction and modelling of hominid origins? How can
palaeoanthropologists give guidance in framing questions or issues
that are feasibly investigated by primatologists? Topics ranged
from bipedality to the use of fire, with each participant posing,
sometimes provocatively, points of interest, seeking engagement
with the others. The general result was that there were many more
interfaces that either side had previously suspected, and future
AWG activities will follow up on these.
FE, NEW MEXICO, USA
with broad experience and interests in tephra studies from Canada,
Eritrea, Ethiopia, Japan, Kenya, and the United States attended
the Revealing Hominid Origins Initiative (RHOI) Tephra Analytical
Working Group workshop at the Radisson Hotel, Santa Fe, New Mexico,
between March 12, 2005 and March 16, 2005. The workshop started
with keynote lectures on tephra studies in western Canada and Alaska,
East Africa, Antarctica, and on the proposed Gulf of Aden drilling.
Moreover, presentations were given by other workshop participants
on their current research activities in different parts of the African
Rift System in Eritrea, Ethiopia, and Kenya.
Suid Analytical Working Group held its initial meeting in Addis
Ababa (Ethiopia). The meeting icluded coordinator Yohannes Haile-Selassie,
Raymond Bernor, Michel Brunet, Scott Simpson and Tim White. The
participants discussed the AWG structure, its principal concerns,
and the need to delineate important and pressing research issues.
These concerns included comparative studies of the other African
suid collections, the need to make available for study newly recovered,
still unprepared collection(s) in Ethiopia and elsewhere, and the
focus of analytical studies on issues of definition and synonomy
and the elaboration and definitiont of FAD and LAD events on the
basis of much expanded and temporally controlled fossil record.
FRANCISCO, CALIFORNIA, USA
meeting of the RHOI Cercopithecid Analytical Working Group (Nina
Jablonski, Brenda Benefit, Eric Delson, Gerald Eck, Steven Frost,
Leslea Hlusko, but sans M. Leakey) was held December 3rd and 4th
of 2004 in San Francisco. The presentations and subsequent
discussions resulted in the development of several 'working subgroups'
charged with undertaking specific tasks and intellectual initiatives,
including: 1) Collation of basic specimen identification
and locality information for relevant fossils following RHOI protocols;
2) Integration of molecular, paleontological, and paleoenvironmental
data to shed light on the phylogenetic and biographic histories
of lineages; 3) Approaches to understanding the history of
adaptation in the group, especially the history of folivory; 4)
Utilization of morphometric approaches to the study of phylogeny;
and 5) Coping with recalcitrant taxonomic problems within the tribe
Papionini. Individuals with expertise in relevant areas were
identified and will be recruited to assist in the work of appropriate

RHOI Taphonomy AWG (Christiane Denys, Peter Andrews, Aude Bergeret,
Antoine Louchart, Yolanda Fernandez-Jalvo, and Thalassa Matthews)
met in Paris in September of 2004. Discussions centered on establishing
a uniform approach to taphonomic studies for various RHOI endeavors.
A standardized field protocol was established and will be written
and presented on the RHOI website.
