Denisovan Portrait Drawn From
IN FOCUS NEWS trees across 13 provinces in the country’s north since the programme began in 1978. Around 2000, deserts across the country MAAYAN HAREL MAAYAN were expanding by 10,400 square kilometres a year, says the government. But in 2017, it reported that China’s deserts were shrinking by more than 2,400 square kilometres a year. A 2018 study1 of satellite data from the US National Oceanic and Atmospheric Administration found that forest cover has increased in line with government statistics, but suggested that changes in logging policy were more important than afforestation — planting forests where none were before. In 1999, the Chinese government began planting millions of trees in its Grain for Green Program, intended to repair dam- aged farmland in the northern Loess Plateau, which is roughly the size of France. And the afforestation drive is continuing apace: in 2018, the government announced a target of 30% forest coverage by 2050. At the moment, the coverage is around 22%. It’s still too early to determine whether it has solved the problem, says Congbin Fu, director of the Institute for Climate and Global Change Research at Nanjing University.

There are pitfalls to mass tree-planting. ANCIENT HUMANS Large parts of China — including some areas where trees are being planted — are getting drier. A paper2 co-authored by Sternberg found that arid areas in China had increased Denisovan portrait by roughly 1.6 million square kilometres, about the size of Iran, since 1980 — probably due largely to anthropogenic climate change. -
No Evidence for Recent Selection at FOXP2 Among Diverse Human Populations
Article No Evidence for Recent Selection at FOXP2 among Diverse Human Populations Graphical Abstract Authors Elizabeth Grace Atkinson, Amanda Jane Audesse, Julia Adela Palacios, Dean Michael Bobo, Ashley Elizabeth Webb, Sohini Ramachandran, Brenna Mariah Henn Correspondence [email protected] (E.G.A.), [email protected] (B.M.H.) In Brief An in-depth examination of diverse sets of human genomes argues against a recent selective evolutionary sweep of FOXP2, a gene that was believed to be critical for speech evolution in early hominins. Highlights d No support for positive selection at FOXP2 in large genomic datasets d Sample composition and genomic scale significantly affect selection scans d An intronic ROI within FOXP2 is expressed in human brain cells and cortical tissue d This ROI contains a large amount of constrained, human- specific polymorphisms Atkinson et al., 2018, Cell 174, 1424–1435 September 6, 2018 ª 2018 Elsevier Inc. https://doi.org/10.1016/j.cell.2018.06.048 Article No Evidence for Recent Selection at FOXP2 among Diverse Human Populations Elizabeth Grace Atkinson,1,8,9,10,* Amanda Jane Audesse,2,3 Julia Adela Palacios,4,5 Dean Michael Bobo,1 Ashley Elizabeth Webb,2,6 Sohini Ramachandran,4 and Brenna Mariah Henn1,7,* 1Department of Ecology and Evolution, Stony Brook University, Stony Brook, NY, USA 2Department of Molecular Biology, Cell Biology and Biochemistry, Brown University, Providence, RI 02912, USA 3Neuroscience Graduate Program, Brown University, Providence, RI 02912, USA 4Department of Ecology and Evolutionary -

Where did they obsidian from Inyo County over 300 miles away, live? How were they able to survive? At our showing that these people had an extensive meeting on Monday, December 11 at 6 pm in trade network.2 the Chula Vista Library, Dennis Gallegos will answer these questions. His new book, First The First People may have come to the South People: A Revised Chronology for San Diego Bay long before those found at Remington Hills. County, examines the archaeological evidence Scientists from the San Diego Natural History going back to the end of the Ice Age 10,000 Museum have examined mastodon bones years ago. The ancestors of todayʼs Kumeyaay may have come down the coast from the shrinking Bering land bridge. Ancestors who spoke the ancient Hokan language may have come from the east, overland from the receding waters of the Great Basin. These early people (Californiaʼs first migrants) were called the “Scraper-Makers” by the pioneering archaeologist Malcolm Rogers in the 1920s.1 The name came from the stone tools that Rogers discovered at many sites in San Diego County, from the San Dieguito River in the north to the Otay River in the south. Rogers described their culture as the “San Dieguito pattern” based on his research at the Harris site near Lake Hodges on the San Dieguito River. This same cultural pattern and stone tools have been found at the Remington Hills site in western Otay Mesa. -

Evolution of the 'Homo' Genus
MONOGRAPH Mètode Science StudieS Journal (2017). University of Valencia. DOI: 10.7203/metode.8.9308 Article received: 02/12/2016, accepted: 27/03/2017. EVOLUTION OF THE ‘HOMO’ GENUS NEW MYSTERIES AND PERSPECTIVES JORDI AGUSTÍ This work reviews the main questions surrounding the evolution of the genus Homo, such as its origin, the problem of variability in Homo erectus and the impact of palaeogenomics. A consensus has not yet been reached regarding which Australopithecus candidate gave rise to the first representatives assignable to Homo and this discussion even affects the recognition of the H. habilis and H. rudolfensis species. Regarding the variability of the first palaeodemes assigned to Homo, the discovery of the Dmanisi site in Georgia called into question some of the criteria used until now to distinguish between species like H. erectus or H. ergaster. Finally, the emergence of palaeogenomics has provided evidence that the flow of genetic material between old hominin populations was wider than expected. Keywords: palaeogenomics, Homo genus, hominins, variability, Dmanisi. In recent years, our concept of the origin and this species differs from H. rudolfensis in some evolution of our genus has been shaken by different secondary characteristics and in its smaller cranial findings that, far from responding to the problems capacity, although some researchers believe that that arose at the end of the twentieth century, have Homo habilis and Homo rudolfensis correspond to reopened debates and forced us to reconsider models the same species. that had been considered valid Until the mid-1970s, there for decades.

www.nature.com/scientificreports OPEN The human EDAR 370V/A polymorphism afects tooth root morphology potentially through the modifcation of a reaction–difusion system Keiichi Kataoka1,2, Hironori Fujita3,4,5, Mutsumi Isa1, Shimpei Gotoh1,2, Akira Arasaki2, Hajime Ishida1 & Ryosuke Kimura1* Morphological variations in human teeth have long been recognized and, in particular, the spatial and temporal distribution of two patterns of dental features in Asia, i.e., Sinodonty and Sundadonty, have contributed to our understanding of the human migration history. However, the molecular mechanisms underlying such dental variations have not yet been completely elucidated. Recent studies have clarifed that a nonsynonymous variant in the ectodysplasin A receptor gene (EDAR 370V/A; rs3827760) contributes to crown traits related to Sinodonty. In this study, we examined the association between the EDAR polymorphism and tooth root traits by using computed tomography images and identifed that the efects of the EDAR variant on the number and shape of roots difered depending on the tooth type. In addition, to better understand tooth root morphogenesis, a computational analysis for patterns of tooth roots was performed, assuming a reaction–difusion system. The computational study suggested that the complicated efects of the EDAR polymorphism could be explained when it is considered that EDAR modifes the syntheses of multiple related molecules working in the reaction–difusion dynamics. In this study, we shed light on the molecular mechanisms of tooth root morphogenesis, which are less understood in comparison to those of tooth crown morphogenesis. Morphological variations in human teeth have been well studied in the feld of dental anthropology 1,2. -
