Genetic Evidence How Man Migrated To Europe
2013-08-12 14:47:31

Brett Smith for redOrbit.com - Your Universe Online Humans emerged en masse from Africa thousands of years ago, but scientists still aren’t sure about the exact routes they took as they set out to populate the planet. According to a new DNA analysis from an international team of researchers, human expansion most likely occurred after the Last Glacial Maximum, between 26,500 and 19,000 years ago, and the Neolithic Era, approximately 12,000 years ago. The researchers reached their...

Study Finds Genetic Trail Linking Early Australian Inhabitants With Indians

Brett Smith for redOrbit.com - Your Universe Online A new study in the early online edition of the journal Proceedings of the National Academy of Sciences (PNAS) from geneticists at the Max Planck Institute in Leipzig, Germany could lead to a rewriting of the cultural history of Australia. The researchers say that a recent genetic analysis shows evidence of a substantial flow of genes running between the Indian and Australian populations about 4,000 years ago. "Interestingly, this...

Largest Genomic Study Finds Khoe-San Peoples Are Unique

Some 220 individuals from different regions in southern Africa participated in the research that led to the analysis of around 2.3 million DNA variants per individual — the biggest ever Genetically, culturally and ethically the Khoe-San have something special to add to this world. The importance of this study is to put the Khoe and San heritage in the right place in history and this research will provide a genetic backdrop for future studies - Mattias Jakobsson. The largest...

Neanderthals And Humans - Interbreeding Or Common Ancestry
2012-08-14 07:51:50

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Cambridge finds that the DNA similarities between Neanderthals and modern humans are more likely to have arisen from a shared common ancestor than from interbreeding. Previously, it has been suggested that the shared parts of the genome sequence between the two populations was the result of interbreeding, but the new research, published this week in the journal Proceedings of the National Academy of...

Diversity within Ethiopian genomes reveals imprints of historical events Researchers have started to unveil the genetic heritage of Ethiopian populations, who are among the most diverse in the world, and lie at the gateway from Africa. They found that the genomes of some Ethiopian populations bear striking similarities to those of populations in Israel and Syria, a potential genetic legacy of the Queen of Sheba and her companions. The team detected mixing between some Ethiopians and...

An international team of scientists, including researchers from Murdoch University, have just published findings that re-interpret the history of our species' original dispersals across the planet. Using a piece of hair donated by a West Australian Aboriginal man around 100 years ago, the team sequenced an individual's entire DNA code (or genome) to prove that multiple dispersals of early humans populated the world, contrary to the commonly-held single dispersal theory. Perth, Western...

Modern humans never co-existed with Homo erectus"”a finding counter to previous hypotheses of human evolution"”new excavations in Indonesia and dating analyses show. The research, reported in the journal PLoS One, offers new insights into the nature of human evolution, suggesting a different role for Homo erectus than had been previously thought. The work was conducted by the Solo River Terrace (SoRT) Project, an international group of scientists directed by anthropologists Etty...

Genetic research indicates that Australian Aborigines initially arrived via south Asia. Researchers writing in the open access journal BMC Evolutionary Biology have found telltale mutations in modern-day Indian populations that are exclusively shared by Aborigines.Dr Raghavendra Rao worked with a team of researchers from the Anthropological Survey of India to sequence 966 complete mitochondrial DNA genomes from Indian 'relic populations'. He said, "Mitochondrial DNA is inherited only from the...

The Y-chromosome is vital in the study of human evolution, writes Laoise Moore , winner of this year's 'Irish Times'/RIA biochemistry writing competition Our DNA connects us with the past. We inherit DNA, our genetic material, from our parents, who inherited it from their parents, and they from their parents and so on back to the origins of life. Our DNA is organised into 23 pairs of chromosomes, half from each parent. DNA occurs as a code of four letters: A, T, G and C. Variations in this...
