Multiplex amplification of the mammoth mitochondrial genome and the evolution of Elephantidae

Nature, 2005
In studying the genomes of extinct species, two principal limitations are typically the small quantities of endogenous ancient DNA and its degraded condition, even though products of up to 1,600 base pairs (bp) have been amplified in rare cases. Using small overlapping polymerase chain reaction products, longer stretches of sequences or even whole ...

New data on the migration of the family Elephantidae (mammalia, proboscidea) in Eurasia

Doklady Biological Sciences, 2006
103 The family Elephantidae showed a high rate of evolution, early stages of which were confined to Africa, while later stages occurred in Eurasia (the genera Elephas L., 1758; Archidiskodon Nesti, 1825, and Mammuthus Burnet, 1830). The earliest members of the family (assigned to Primelephas gomphoroides Maglio, 1970) were recorded in eastern Africa at

Mitochondrial cytochrome b of the Lyakhov mammoth (Proboscidea, Mammalia): new data and phylogenetic analyses of Elephantidae

Molecular Phylogenetics and Evolution, 2003
The phylogenetic relationships between recent Elephantidae (Proboscidea, Mammalia), that is to say extant elephants (Asian and African) and extinct woolly mammoth, have remained unclear to date. The prevailing morphological scheme (mammoth grouped with Asian elephant) is either supported or questioned by the molecular results.

Origin and radiation of the Elephantidae

1996
Abstract The emergence of the family Elephantidae in the late Miocene of Africa is thought to be correlated with a major adaptive shift in the masticatory apparatus. This shift was a transition from a combined grinding and shearing molar function with some lateral jaw movement, which is characteristic of gomphotheres, to a mostly ...

Analyse cladistique numérique et analyse de parcimonie;l'exemple des Elephantidae

Geobios, 1986
Resume La confrontation des differentes hypotheses publiees ces dernieres annees au sujet de l'origine des Elephantidae a ete l'occasion d'utiliser un programme d'analyse de parcimonie (le «PHYLIP package) et de discuter quelques points methodologiques inherents a l'aspect numerique des approches cladistiques informatisees.

Forensic species identification of elephant (Elephantidae) and giraffe (Giraffidae) tail hair using light microscopy [PDF]

Forensic Science, Medicine, and Pathology, 2010
Here we present methods for distinguishing tail hairs of African elephants (Loxodonta africana), Asian elephants (Elephas maximus), and giraffes (Giraffa camelopardalis) from forensic contexts. Such hairs are commonly used to manufacture jewelry artifacts that are often sold illegally in the international wildlife trade.

A skeleton of Mammuthus trogontherii (Proboscidea, Elephantidae) from NW Peloponnese, Greece

Quaternary International, 2012
Abstract Fossil elephant remains were identified in Loussika, NW Peloponnese, Southern Greece, when tusk fragments were recognized in a bulldozer backfill. An excavation carried out in 2001 and 2003 by the Hellenic Ministry of Culture revealed the partial skeleton of an adult male mammoth, referred to the Middle Pleistocene species Mammuthus ...

Geobios, 1987
Resume A la suite d'un premier article publie dans ces colonnes (Tassy & Darlu 1986), la question des relations de parente des Elephantidae et des gomphotheres de grade tetralophodonte est a nouveau abordee au moyen de nouvelles analyses de parcimonie informatisees.
