Most ancient case of tuberculosis found in 500,000-year-old human; points to modern health issues

Although most scientists believe tuberculosis emerged only several thousand years ago, new research from the University of Texas at Austin reveals the most ancient evidence of the disease has been found in a 500,000-year-old human fossil from Turkey.The discovery of the new specimen of the human species, Homo erectus, suggests support for the theory that dark-skinned people who migrate northward from low, tropical latitudes produce less vitamin D, which can adversely affect the immune system as well as the skeleton.

2. More human-Neandertal mixing evidence uncovered
   11-02-2006 · EurekAlert!
   A reexamination of ancient human bones from Romania reveals more evidence that humans and Neandertals interbred. Erik Trinkaus, Ph.D., Washington University Mary Tileston Hemenway Professor in Arts & Sciences, and colleagues radiocarbon-dated and analyzed the shapes of human bones from Romania's Petera Muierii (Cave of the Old Woman). The fossils, discovered in 1952, add to the small number of early modern human remains from Europe known to be more than 28,000 years old.

   11-15-2006 · EurekAlert!
   454 Life Sciences today announced that comparison of the human and chimpanzee genomes to Neandertal DNA sequences determined by 454 Sequencing reveals that modern human and Neandertal DNA sequences diverged on average about 500,000 years ago and the effective size of the ancestral population of the two groups was similar to that of modern humans.

   04-12-2007 · EurekAlert!
   Researchers have sequenced the genome of the relatively ancient rhesus macaque (Macaca mulatta), providing perspective into how humans are genetically different from our primate relatives. In addition to benefiting human health research in areas as diverse as HIV and aging, the genome enhances understanding of primate evolution. The macaque genome research appears in the April 13 issue of Science published by AAAS, the nonprofit science society.

   An international team of scientists have found that the oldest member (160,000 years old) of the genus Homo shows a modern human life history profile. These findings, based on experiments at ESRF, are in contrast to previous studies suggesting that early fossil humans possessed short growth periods, which were more similar to chimpanzees than to living humans.

   The human love affair with chocolate is at least 3,000 years old -- and it began at least 500 years earlier than previously thought, according to new analyses of pottery shards from the Ulua Valley region of northern Honduras. But the first people to appreciate the cacao tree were probably after a fermented drink, say anthropologists at Cornell University.

   Researchers at the Translational Genomics Research Institute (TGen) today announced the discovery of a gene that plays a significant role in memory performance in humans. The study details how researchers associated memory performance with a gene called Kibra in over 1,000 individuals -- both young and old -- from Switzerland and Arizona. This study is the first to describe scanning the human genetic blueprint at over 500,000 positions to identify cognitive differences between humans.
