Native American population history is reexamined using a large data set of pre-Columbian mitochondrial genomes.
Of the six independent centres of civilization in world prehistory, probably least well known is Chavin de Huantar, high up Andes, where South America's oldest complex culture arose during first millennium BC and created its earliest city. The style dominated Peruvian art architecture for hundreds years influenced all that came after. But what was exact nature this style? How did develop, why it eventually collapse? New answers are emerging after unprecedented discoveries made over past two...

Excavations at Quebrada Jaguay 280 (QJ-280) (16 degrees30'S) in south coastal Peru demonstrated that Paleoindian-age people of the Terminal Pleistocene (about 11,100 to 10,000 carbon-14 years before present or about 13,000 11,000 calibrated present) South America relied on marine resources while resident coast, which extends American record maritime exploitation by a millennium. This site supports recent evidence had diverse subsistence systems. The presence obsidian QJ-280 shows inhabitants...

There are many unanswered questions about the population history of Central and South Andes, particularly regarding impact large-scale societies, such as Moche, Wari, Tiwanaku, Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus period rise fall state societies. Today's genetic structure began to develop by 5,800 BP, followed bi-directional gene flow between North Highlands, Highlands Coast. detect minimal admixture among...
Males of Opadometa are difficult to associate with conspecific females, and sex-matching errors may persist in the taxonomic literature. Recommended best practices for definitive sex matching this genus suggest finding a male web female, or better yet, mating pairs.A was observed hanging on frame line female sarawakensis, species which previously undescribed. This occurred during tropical ecology field course held at Danau Girang Field Centre Sabah, Malaysia. A description completed as activity.
Both cinnabar (HgS) and metallic mercury (Hg0) were important resources throughout Andean prehistory. Cinnabar was used for millennia to make vermillion, a red pigment that highly valued in pre-Hispanic Peru; Hg0 has been since the mid-16th century conduct amalgamation, an efficient process of extracting precious metals from ores. However, little is known about which deposits exploited by cultures, environmental consequences Hg mining amalgamation remain enigmatic. Here we use isotopes...
Ancient DNA traces the history of hepatitis B Hepatitis virus (HBV) infections represent a worldwide human health concern. To study this pathogen, Kocher et al . identified 137 remains with detectable levels dating between 400 and 10,000 years ago. Sequencing analyses these ancient viruses suggested common ancestor 12,000 20,000 There is no evidence indicating that HBV was present in earliest humans as they spread out Africa; however, likely populations before farming. Furthermore, Americas...
Scholars frequently posit maize as the staple food of Chavín civilization and some even argue that this crop provided critical stimulus for its development. Stable carbon isotope analysis permits an evaluation these hypotheses because maize, only C 4 cultigen consumed in pre‐Hispanic Peru, leaves unambiguous imprint on bone chemistry consumers allows calculation relative importance diet. Analysis osteological samples from de Huántar Huaricoto indicates although was eaten, 3 foods like...
Adenylate deaminase from brain is activated by adenosine triphosphate (l-4).Early studies showed that adenylate activity widely distributed in animal tissues (5).No evidence was presented previously the other than affected nucleoside triphosphates.This communication reports addition to being triphosphate, enzyme strongly inhibited guanosine triphosphate.A similar occurs many rat tissues.It proposed this type of involved regulating relative amounts adenine, hypoxanthine, and guanine...
Analysis of the animal bones recovered from excavations residential contexts at Chavín de Huántar reveals a mixed economy that included herding and hunting camelids (llama vicuña) as early Urabarriu Phase (900–500 B.C.). It also suggests pattern trade in dried llama meat ( ch'arki ) high altitude environments punas to lower ones had developed by Chakinani phase (500–400 B.C.), while consumption hunted animals (especially deer) sharply declined importance. During apogee (400–200 socioeconomic...
Abstract Re‐introduction of rare species to parts their historical range is becoming increasingly important as a conservation strategy.

There it vulnerable stochastic events, including the introduction alien predators that may either prey upon or compete for food resources. Consequently, skinks have been introduced le aux A igrettes, another small M auritian island has...
Abstract In 1999, the Quispisisa source of obsidian was located in Province Huanca Sancos central Ayacucho near village Sacsamarca. This discovery has been confirmed at University Missouri Research Reactor (MURR) by comparing neautron activation analyses samples with artifacts. The volcanic glass provided raw material for most artifacts utilized and northern Peru throughout prehispanic times.
The emergence of public architecture in Peru's central highlands occurred during the mid-first millennium B. C. and is correlated with expansion Chavín sphere interaction. Atalla, a high-altitude site Huancavelica, represents one first known centers large-scale masonry constructions. Analysis ceramic assemblage reveals many similarities between local ceramics Janabarriu phase pottery from de Huántar, located 450 km to north. inhabitants Atalla emulated style cut-stone much larger northern...
AbstractThe 1987/1988 field season at the U-shaped civic ceremonial center of Cardal in Lurin Valley, Peru, included mapping and excavation public domestic architecture. Occupied from 1150 to 800 b.c., provides evidence a more elaborate ground plan than was previously recognized, including dual causewayed plazas, 10 semisubterranean circular courts. Excavations architecture revealed periodic burial construction ritual buildings, steep central stairway an atrium whose exterior wall decorated...
