Scientists discovered bacteria in people from Africa and South America that may have been transmitted from common ancestors
Researchers discovered that Indigenous populations in Bolivia and Tanzania share similar gut bacteria, suggesting these microbes have been passed down through human generations for thousands of years. The study highlights a core microbiome that may have traveled with ancient human migrations.
Why it matters
Understanding the evolution of the human microbiome provides insights into human history and potential health implications for modern populations.
Scientists discovered more than 1,200 species of intestinal bacteria. Some of the microorganisms may have been passed down to humans from common ancestors.
American scientists have discovered a remarkable similarity between the gut bacteria of two Indigenous peoples living on different continents. The study suggests that some microorganisms may have accompanied humanity for thousands of years, passing from generation to generation during ancient migrations. The University of California, Santa Barbara, reports this, citing a study published in the journal Nature, UNN writes.
Scientists from the University of California, Santa Barbara, and Stanford University studied the gut microbiome of the Tsimané people, who live in Bolivia, and the Hadza people, whose members live in Tanzania and maintain a traditional hunter-gatherer way of life.
