Published Fossil hotspots in Africa obscure a more complete picture of human evolution (via sciencedaily.com) Original source
A new study shows how the mismatch between where fossils are preserved and where humans likely lived may influence our understanding of early human evolution.
Published Decoding the world's largest animal genome (via sciencedaily.com) Original source
Scientists have sequenced the largest genome of all animals, the lungfish genome. Their data help to explain how the fish-ancestors of today's land vertebrates were able to conquer land.
Published Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis (via sciencedaily.com) Original source
A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.
Published Genetic signatures of domestication identified in pigs, chickens (via sciencedaily.com) Original source
Wild boars and red junglefowl gave rise to common pigs and chickens. These animals' genes evolved to express themselves differently, leading to signatures of domestication -- such as weaker bones and better viral resistance -- in pigs and chickens, according to a research team.
Published Half a billion-year-old spiny slug reveals the origins of mollusks (via sciencedaily.com) Original source
Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
Published Ancient microbes offer clues to how complex life evolved (via sciencedaily.com) Original source
Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how complex organisms may have acquired some of their genes and highlights the dynamic interplay between viruses and their hosts.
Published Insight into one of life's earliest ancestors revealed in new study (via sciencedaily.com) Original source
Researchers have shed light on Earth's earliest ecosystem, showing that within a few hundred million years of planetary formation, life on Earth was already flourishing.
Published 'A history of contact': Geneticists are rewriting the narrative of Neanderthals and other ancient humans (via sciencedaily.com) Original source
Using genomes from 2,000 living humans as well as three Neanderthals and one Denisovan, an international team mapped the gene flow between the hominin groups over the past quarter-million years.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds (via sciencedaily.com) Original source
A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published Extinct humans survived on the Tibetan plateau for 160,000 years (via sciencedaily.com) Original source
Bone remains found in a Tibetan cave 3,280 m above sea level indicate an ancient group of humans survived here for many millennia.
Published First case of Down syndrome in Neanderthals documented in new study (via sciencedaily.com) Original source
A new study documents the first case of Down syndrome in Neanderthals and reveals that they were capable of providing altruistic care and support for a vulnerable member of their social group.
Published Origins of cumulative culture in human evolution (via sciencedaily.com) Original source
Cumulative culture -- the accumulation of technological modifications and improvements over generations -- allowed humans to adapt to a diversity of environments and challenges. But, it is unclear when cumulative culture first developed during hominin evolution. A new study concludes that humans began to rapidly accumulate technological knowledge through social learning around 600,000 years ago.
Published Early Homo sapiens facilitated the establishment of the Bonelli's eagle in the Mediterranean 50,000 years ago (via sciencedaily.com) Original source
Scientists have unraveled the ancestral history of one of the most iconic birds of prey in the current Iberian fauna: the Bonelli's eagle (Aquila fasciata). The study combines evidence from several disciplines, including palaeontology, genetics and ecology, to answer questions about when and why the Bonelli's eagle, a species primarily found in tropical and subtropical areas, colonized the Mediterranean Basin.
Published Bringing back an ancient bird (via sciencedaily.com) Original source
Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.
Published 75,000-year-old female Neanderthal from cave where species buried their dead (via sciencedaily.com) Original source
A new documentary has recreated the face of a 75,000-year-old female Neanderthal whose flattened skull was discovered and rebuilt from hundreds of bone fragments by a team of archaeologists and conservators.
Published Revised dating of the Liujiang skeleton renews understanding of human occupation of China (via sciencedaily.com) Original source
Researchers have provided new age estimates and revised provenance information for the Liujiang human fossils, shedding light on the presence of Homo sapiens in the region. Using advanced dating techniques including U-series dating on human fossils, and radiocarbon and optically stimulated luminescence dating on fossil-bearing sediments, the study revealed new ages ranging from approximately 33,000 to 23,000 years ago. Previously, studies had reported ages of up to 227,000 years of age for the skeleton.
Published How evolving landscapes impacted First Peoples' early migration patterns into Australia (via sciencedaily.com) Original source
Scientists have applied a dynamic model of the landscape to patterns of human migration into Sahul, the combined continent of Australia, Tasmania and New Guinea.
Published More plants on the menu of ancient hunter-gatherers (via sciencedaily.com) Original source
It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.
Published Genetic variant identified that shaped the human skull base (via sciencedaily.com) Original source
Researchers have identified a variant in the gene TBX1 as key in the development of the unique morphology at the base of the skull. TBX1 is present at higher levels in humans than in closely related hominins. Low TBX1 also occurs in certain genetic conditions causing altered skull base morphology. This study provides a greater understanding of human disease and evolution.
Published Interspecies competition led to even more forms of ancient human -- defying evolutionary trends in vertebrates (via sciencedaily.com) Original source
Competition between species played a major role in the rise and fall of hominins -- and produced a 'bizarre' evolutionary pattern for the Homo lineage -- according to a new study that revises the start and end dates for many of our early ancestors.
