Los primeros agricultores y ganaderos. Excavaciones en el yacimiento del Neolítico Precerámico A y B de Kharaysin (Zarqa, Jordania). Campañas de 2015 y 2016

[EN] Kharaysin is a Pre-Pottery Neolithic A and Pre-Pottery Neolithic B site, dated between the end of the 10th millennium and the first half of the 8th millennium cal BC. It is located at the village of Quneya, by the Zarqa River, with 25 ha in extension. Up to the present, four phases of occupation have been discovered, two corresponding to the PPNA and two to the PPNB. The abundant instruments, human, animal and botanical remains, figurines and so on recovered in Kharaysin allow us considering Kharaysin as a key site for understanding the first sedentary villages and the process of invention of agriculture and livestock in northern Jordan.[ES] Kharaysin es un yacimiento datado en el Neolítico Precerámico A y B, entre finales del x y la primera mitad del viii milenio cal a. C., situado en el pueblo de Quneya, junto al río Zarqa, con 25 ha de extensión. Por el momento se han detectado cuatro fases de ocupación: dos correspondientes al Precerámico A y otras dos al B. La abundancia de restos humanos, de utillaje, faunísticos y arqueobotánicos recuperados hace de Kharaysin un yacimiento clave para comprender los orígenes de la agricultura y la ganadería, así como el proceso de sedentarización de las poblaciones en el norte de Jordania.Peer reviewe

The complete mitochondrial and plastid genomes of Corallina chilensis (Corallinaceae, Rhodophyta) from Tomales Bay, California, USA

Genomic analysis of the marine alga Corallina chilensis from Tomales Bay, California, USA, resulted in the assembly of its complete mitogenome (GenBank accession number MK598844) and plastid genome (GenBank MK598845). The mitogenome is 25,895 bp in length and contains 50 genes. The plastid genome is 178,350 bp and contains 233 genes. The organellar genomes share a high-level of gene synteny to other Corallinales. Comparison of rbcL and cox1 gene sequences of C. chilensis from Tomales Bay reveals it is identical to three specimens from British Columbia, Canada and very similar to a specimen of C. chilensis from southern California. These genetic data confirm that C. chilensis is distributed in Pacific North America
