Dissecting the influence of Neolithic demic diffusion on Indian Y-chromosome pool through J2-M172 haplogroup. [PDF]

Sci Rep, 2016
AbstractThe global distribution of J2-M172 sub-haplogroups has been associated with Neolithic demic diffusion. Two branches of J2-M172, J2a-M410 and J2b-M102 make a considerable part of Y chromosome gene pool of the Indian subcontinent. We investigated the Neolithic contribution of demic dispersal from West to Indian paternal lineages, which majorly ...

Not by Selection Alone: Expanding the Scope of Gene-Culture Coevolution. [PDF]

Evol Anthropol
ABSTRACT Gene‐culture coevolution (GCC)—an ambitious synthesis of biological and social sciences is often used to explain the evolution of key human traits. Despite the framework's broad conceptual appeal however, empirical evidence is often perceived as limited to a few key examples like lactase persistence.

Tracing the origin and spread of agriculture in Europe. [PDF]

PLoS Biology, 2005
The origins of early farming and its spread to Europe have been the subject of major interest for some time. The main controversy today is over the nature of the Neolithic transition in Europe: the extent to which the spread was, for the most part ...

Cultural diffusion was the main driving mechanism of the Neolithic transition in southern Africa. [PDF]

PLoS ONE, 2014
It is well known that the Neolithic transition spread across Europe at a speed of about 1 km/yr. This result has been previously interpreted as a range expansion of the Neolithic driven mainly by demic diffusion (whereas cultural diffusion played a ...

Developmental models shed light on the earliest dental tissues, using Astraspis as an example

Palaeontology, Volume 66, Issue 6, November/December 2023., 2023
Abstract Fossils of extinct jawless vertebrates are pivotal to deciphering the evolutionary paths that led to the various forms of the vertebrate skeleton. For example, Pteraspidomorphs (stem‐gnathostomes), such as the Ordovician Astraspis, display some of the oldest remains of bony and ‘dental’ (dentine and enameloid) tissues.

Testing heterochrony: Connecting skull shape ontogeny and evolution of feeding adaptations in baleen whales

Evolution &Development, Volume 25, Issue 4-5, Page 257-273, July 2023., 2023
Changes in Mysticeti skull development are coupled with the evolution of different feeding modes. Species with larger sizes surprisingly have a slower developmental rate (Balaenoptera and Megaptera—rorqual whales), connected with the evolution of lunge filter feeding.

Exploring the relationships between genetic, linguistic and geographic distances in Bantu‐speaking populations

American Journal of Biological Anthropology, Volume 179, Issue 1, Page 104-117, September 2022., 2022
Abstract Objectives The predominance of Bantu languages in sub‐Saharan Africa has sparked a large debate over the processes through which they came to disperse over time and space—the “Bantu expansion.” The overall genetic similarity shown by Bantu‐speaking populations indicates that movement of people occurred too, but the extent of the correlation ...

“Celts” up and down the Alps. Insights on mobility patterns in the pre‐Roman/Celtic population from Verona (NE Italy, 3rd–1st c. BCE): A multi‐isotopic approach

American Journal of Biological Anthropology, Volume 178, Issue 3, Page 513-529, July 2022., 2022
Abstract Objectives The Late Iron Age in continental Europe featured complex demographic processes including, among others, the establishment of transalpine “Celtic” communities on the Italian peninsula between the 4th and 1st centuries BCE. To date, only few data are available about mobility and migration in these populations.

Predominant frequency of HLA‐B*27 in patients with ankylosing spondylitis in southeastern China

Immunity, Inflammation and Disease, Volume 9, Issue 4, Page 1696-1701, December 2021., 2021
Abstract Objectives This study was to investigate the polymorphism and distribution of alleles of HLA‐B*27 in patients with ankylosing spondylitis (AS) in Han population of southeastern China. Methods A total of 89 peripheral blood samples from southeastern Chinese Han patients with AS that diagnosed according to Modified New York criteria were ...
