Prehistoric origins of stomach ulcers uncovered

Scientists have discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. They compared DNA sequence patterns of humans and the Helicobacter pylori bacteria now known to cause most stomach ulcers and found that the genetic differences between human populations that arose as they dispersed from Eastern Africa over thousands of years are mirrored in H.pylori.

6. Salt increases ulcer-bug virulence
   05-22-2007 · EurekAlert!
   Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease.

    07-18-2007 · EurekAlert!
    New research published in the journal Nature July 19 has proved the single origin of humans theory by combining studies of global genetic variations in humans with skull measurements across the world. The research, at the University of Cambridge and funded by the Biotechnology and Biological Sciences Research Council, represents a final blow for supporters of a multiple origins of humans theory.
