Nouvel article sur l'homme de flores
Comme chacun sait je suis très très intéressé par les nouvelles découvertes sur les hommes préhistorique en tant que préhistorien, normal. Est ce que quelqu'un parmi vous a entendu parlé du nouvel article sur L'homme de flores? J'aimerais bien avoir le PDF si quelqu'un l'a.
Merci.

Plusieurs articles sont sortis (ou en cours) cette année dans Journal of Human Evolution (tout un numéro visiblement, dans pubmed tu trouveras les références) dont celui-ci entre autres qui me paraît intéressant :
Homo floresiensis: A cladistic analysis
Journal of Human Evolution, In Press, Corrected Proof, Available online 23 July 2009
Debbie Argue, Mike Morwood, Thomas Sutikna, Jatmiko, Wahyu Saptomo
The announcement of a new species, Homo floresiensis, a primitive hominin that survived until relatively
recent times is an enormous challenge to paradigms of human evolution. Until this announcement, the
dominant paradigm stipulated that: 1) only more derived hominins had emerged from Africa, and 2)
H. sapiens was the only hominin since the demise of Homo erectus and Homo neanderthalensis. Resistance
to H. floresiensis has been intense, and debate centers on two sets of competing hypotheses: 1) that it is
a primitive hominin, and 2) that it is a modern human, either a pygmoid form or a pathological individual.
Despite a range of analytical techniques having been applied to the question, no resolution has
been reached. Here, we use cladistic analysis, a tool that has not, until now, been applied to the problem,
to establish the phylogenetic position of the species. Our results produce two equally parsimonious
phylogenetic trees. The first suggests that H. floresiensis is an early hominin that emerged after Homo
rudolfensis (1.86 Ma) but before H. habilis (1.66 Ma, or after 1.9 Ma if the earlier chronology for H. habilis is
retained). The second tree indicates H. floresiensis branched after Homo habilis.

Ce serait le minimum de fournir les références d'abord non ?
