The Neanderthal Genome project and beyond [PDF]

, 2009
No existeix actualment un consens per a una definició científica de la nostra pròpia espècie. Les anàlisi genòmiques de diferents poblacions humanes estan mostrant una variació interindividual més gran de l'esperada.

PCR and paleogenetics: for best and for worst

, 2021
In the middle of the 1980s, extraction and analysis of DNA preserved in biologicalremains of the past yielded the first results, giving rise to a new scientific field, paleogenetics.Its first successes were obtained thanks to the advent of PCR.

Postglacial Recolonization of the Southern Ocean by Elephant Seals Occurred From Multiple Glacial Refugia

Global Change Biology, Volume 31, Issue 3, March 2025.
Genetic data, alongside historic, archaeological, and subfossil remains, show that Australasian populations of the southern elephant seal have been shaped by range expansions and contractions following the Last Glacial Maximum, with subsequent contractions during the late Holocene. These expansion and contraction events are likely to have been a direct

Dentition of the Mugharet El'Aliya Fossil Human Maxilla, Morocco

American Journal of Biological Anthropology, Volume 186, Issue 2, February 2025.
ABSTRACT Objective This study follows up on our recent morphological analysis of the juvenile maxilla from Mugharet el'Aliya, Morocco. Although this specimen shows a reportedly archaic morphology, likely due to its large size, 3D shape analyses indicated affinities with early Homo sapiens. Here, we conducted an in‐depth comparative investigation of the

Ethics and applications of isotope analysis in archaeology

American Journal of Biological Anthropology, Volume 186, Issue 1, January 2025.
Abstract This synthesis explores specific ethical questions that commonly arise in isotopic analysis. For more than four decades, isotope analysis has been employed in archeological studies to explore past human and animal dietary habits, mobility patterns, and the environment in which a human or animal inhabited during life.

Human Y chromosome haplogroup L1-M22 traces Neolithic expansion in West Asia and supports the Elamite and Dravidian connection

iScience
Summary: West and South Asian populations profoundly influenced Eurasian genetic and cultural diversity. We investigate the genetic history of the Y chromosome haplogroup L1-M22, which, while prevalent in these regions, lacks in-depth study.

Analysis of COI and ITS2 regions of DNA obtained from Paragonimus westermani eggs in ancient coprolites on Joseon dynasty mummies

Memorias do Instituto Oswaldo Cruz, 2019
The genetic information of ancient Paragonimus westermani, the oriental lung fluke infecting over 20 million people worldwide, has not been thoroughly investigated thus far. We analysed genetic markers (COI and ITS2) of P.

Post‐Glacial Vegetation Trajectories on the Eastern Tibetan Plateau Reflect Millennial‐Scale Migration Lags in Complex Mountain Terrain Based on Sedimentary Ancient DNA and Dynamic Dispersal Modeling

Ecology and Evolution, Volume 15, Issue 1, January 2025.
This study investigates how mountain plant species on the eastern Tibetan Plateau responded to postglacial climate change, with a focus on the role of terrain‐driven connectivity to refugia. By combining sedaDNA metabarcoding and species dispersal modeling, we demonstrate that differences in connectivity to refugia led to distinct vegetation ...

Paleogenetic study on the 17th century Korean mummy with atherosclerotic cardiovascular disease

PLOS ONE, 2017
While atherosclerotic cardiovascular disease (ASCVD) is known to be common among modern people exposed to various risk factors, recent paleopathological studies have shown that it affected ancient populations much more frequently than expected. In 2010, we investigated a 17th century Korean female mummy with presumptive ASCVD signs.

Rewilding through inappropriate species introduction: The case of European bison in Spain

Conservation Science and Practice, Volume 6, Issue 12, December 2024.
The increasing pressure to release bisons as a wild species in Spain, as an ecological analogue of the extinct steppe bison Bison priscus, makes it an excellent example to reflect on whether the rewilding of Europe would be, or not, biogeographically advisable. We scrutiny this proposal taking into account the best available evidence on the species, in
