New Clues About Human Ancestry
2013-08-02 05:16:23

redOrbit Staff & Wire Reports - Your Universe Online For the first time, scientists have been able to trace human ancestry through the male line by sequencing the DNA of multiple entire Y chromosomes - and this so-called "Adam" lived during roughly the same time period as the female most recent common ancestor (MRCA), mitochondrial "Eve," they have discovered. The MRCAs, mitochondrial Eve and Y-chromosomal Adam, are two individuals who passed down a portion of their genomes to the...

Untangling The Branches Of The Tree Of Life
2013-05-15 10:33:57

Vanderbilt University These days, phylogeneticists — experts who painstakingly map the complex branches of the tree of life — suffer from an embarrassment of riches. The genomics revolution has given them mountains of DNA data that they can sift through to reconstruct the evolutionary history that connects all living beings. But the unprecedented quantity has also caused a serious problem: The trees produced by a number of well-supported studies have come to contradictory...

DNA sequenced from ancient skeletons sheds light on how modern European populations formed An international team of scientists, including Dr Paul Brotherton from the University of Huddersfield, reveal that events after the initial migration of farmers into Europe had a major impact on the modern gene pool. The paper, published in Nature Communications, investigates a major component of the maternal population history of modern Europeans by focusing on haplogroup H mitochondrial genomes...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

Evolutionary Tree Of Life Goes Digital
2012-10-17 13:25:34

Brett Smith for redOrbit.com - Your Universe Online Evolutionary biologists have long envisioned creating a diagram, or tree of life, that would detail how different species have evolved from a common ancestry, but the task has been a daunting one for taxonomists who would need multiple reams of paper or computer screens to clearly show the evolutionary descent of each species. A research associate at the Imperial College London, however, has risen to the challenge and created OneZoom,...

Ecology and Phylogenetics-New Views of Earth's Biodiversity
2012-08-06 13:38:37

Scientists report new look at 'patterns in nature' in special issue of journal Ecology View patterns of nature in this photo gallery. Patterns in nature are in everything from ocean currents to a flower's petal. Scientists are taking a new look at Earth patterns, studying the biodiversity of yard plants in the U.S. and that of desert mammals in Israel, studying where flowers and bees live on the Tibetan plateau and how willow trees in America's Midwest make use of water. They're...

Assembling, Visualizing And Analyzing A Tree Of All Life
2012-06-06 03:42:53

National Science Foundation grants will bring together what's known about how species are related A new initiative aims to build a comprehensive tree of life that brings together everything scientists know about how all species are related, from the tiniest bacteria to the tallest tree. Researchers are working to provide the infrastructure and computational tools to enable automatic updating of the tree of life, as well as develop the analytical and visualization tools to study it....

Cypress distribution reflects the breakup of Pangaea In classical mythology, the cypress tree is associated with death, the underworld and eternity. Indeed, the family to which cypresses belong, is an ancient lineage of conifers, and a new study of their evolution affords a unique insight into a turbulent era in the Earth´s history. During the geological era known as the Mesozoic, the continental crust was concentrated in a single huge landmass, the supercontinent Pangea. Pangea...

Large numbers of people moved between Africa and Europe during recent and well-documented time periods such as the Roman Empire, the Arab conquest, and the slave trade, and genetic evidence of these migrations lives on in Europeans today. But were there more ancient migrations? In a study published online today in Genome Research, researchers present the first genetic evidence for prehistoric gene flow between Africa and Europe, dating back as far as 11,000 years ago. To trace the...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
