Research team at Aalto University and Turku PET Centre has revealed how experiencing strong emotions synchronizes brain activity across individuals. Human emotions are highly contagious. Seeing others´ emotional expressions such as smiles triggers often the corresponding emotional response in the observer. Such synchronization of emotional states across individuals may support social interaction: When all group members share a common emotional state, their brains and bodies process...

New Yet Research Project To Look For DNA
2012-05-23 05:27:14

Lee Rannals for RedOrbit.com Wolfson College is taking a giant leap forward by attempting to discover the legendary Yeti through analyzing samples of teeth and hair. The college, which is part of Oxford University, is asking for Yeti samples so it can use the latest DNA technology to analyze the fabled beast's genome against other species in the world. "As part of a larger enquiry into the genetic relationship between our own species Homo sapiens and other hominids, we invite...

(Ivanhoe Newswire)– The human brain is the center of the human nervous system and has the same general structure as the brains of other mammals, but it´s than expected. According to a pair of studies, a partial, duplicate copy of a gene appears to be responsible for the critical features of the human brain that distinguish us from our closest primate kin. The momentous gene duplication event occurred about two or three million years ago, at a critical transition in the evolution...

Blondeness In Solomon Islanders Due To Genetic Variations
2012-05-04 08:38:37

Excess sun exposure, a diet rich in fish, and gene inheritance from ancient explorers and traders, are all possible theories why some dark-skinned indigenous Solomon Islanders are naturally blonde, according to new research published today in the journal Science. The study, led by Stanford University researchers, found that 5 to 10 percent of the indigenous Solomon population have a gene that is responsible for blondeness. The trait, however, is distinctly different from the gene that...

Study in Congo protected area helps researchers understand selective factors in gorilla behavior and reproduction Conservationists with the Wildlife Conservation Society and the Max Planck Institute for Evolutionary Anthropology have found that larger male gorillas living in the rainforests of Congo seem to be more successful than smaller ones at attracting mates and even raising young. The study–conducted over a 12-year period in Nouabalé-Ndoki National Park in the...

Darwinian Selection Continues To Influence Human Evolution
2012-04-30 14:25:37

New evidence proves humans are continuing to evolve and that significant natural and sexual selection is still taking place in our species in the modern world. Despite advancements in medicine and technology, as well as an increased prevalence of monogamy, research reveals humans are continuing to evolve just like other species. Scientists in an international collaboration, which includes the University of Sheffield, analyzed church records of about 6,000 Finnish people born between...

Orangutans Harbor Ancient Primate Alu
2012-04-30 07:51:46

Alu elements infiltrated the ancestral primate genome about 65 million years ago. Once gained an Alu element is rarely lost so comparison of Alu between species can be used to map primate evolution and diversity. New research published in BioMed Central's open access journal Mobile DNA has found a single Alu, which appears to be an ancestral great ape Alu, that has uniquely multiplied within the orangutan genome. Analysis of DNA sequences has found over a million Alu elements within each...

Meat-rich Diet Lead To Earlier Weaning, Helping Speed The Spread Of Humans
2012-04-19 11:35:43

Diets rich in meat helped early mother´s wean their babies at an earlier age and allowed them to have more children, behaviors that may have helped humans spread more quickly across the world and had a profound effect on human evolution, according to new research. Researchers from Lund University in Sweden, publishing their work in the open-access journal PLoS ONE, found a clear connection between eating meat and weaning at an earlier age. They discovered that all mammalian species...

Orangutans may be smarter than previously thought if a new study into the sophisticated way they build nests is any indication. Scientists at The University of Manchester spent a year observing and filming (video footage available) orangutans at a research facility in Indonesia and found they apparently possess complex knowledge of mechanical design and material properties. The great apes — which only live wild in Sumatra and Borneo and are one of man's closest relatives —...

In humans and chimpanzees knowledge is transmitted within a group by means of a majority principle The transmission of knowledge to the next generation is a key feature of human evolution. In particular, humans tend to copy behavior that is demonstrated by many other individuals. Chimpanzees and orangutans, two of our closest living relatives, also socially pass on traditional behavior and culture from one generation to another. Whether and how this process resembles the human one is still...

Homo sapiens
2013-09-24 13:55:52

Homo sapiens is the scientific name for the human species. Homo is the human genus, which also includes Neanderthals and various other extinct species of hominid. H. sapiens is the only surviving species of the genus Homo. Modern humans are the subspecies Homo sapiens sapiens, distinguished from their direct ancestor, Homo sapiens idaltu (http://en.wikipedia.org/wiki/Homo_sapiens_idaltu). Subspecies of H. sapiens include Homo sapiens idaltu, roughly translated as “elder wise human” and...

The common chimpanzee (Pan troglodytes), also known as the robust chimpanzee, is a great ape. Basic facts Common chimpanzees are found in the tropical forests and wet savannas of Western and Central Africa. They once inhabited most of this region, but their habitat has been dramatically reduced in recent years. Adults in the wild weigh between 88 and 143 lbs (40 and 65 kg). Males can measure up to 63 inches (160 cm) and females up to 51 inches (130 cm). They are lighter than humans...
