By combining mitochondrial DNA and climatic data, an international team of researchers found that an early mitochondrial lineage emerged in a paleo-wetland.
The researchers traced the timing of when these clusters developed to the emergence of agriculture in three river valleys.
With ancient mitochondrial sequences from all seven Canary Islands, researchers identified at least two early migrations involving shifting populations from North Africa.
Researchers have uncovered three families in which individuals inherited mitochondrial DNA from their fathers, upending existing belief.
By sequencing a handful of individuals who lived in Morocco some 13,900 to 15,100 years ago, investigators found clues to past population mergers in North Africa.
A mitochondrial genome- and Y chromosome marker-based analysis suggests the Chachapoyas population was not completely replaced by Incas as previously believed.
University of Pennsylvania researchers sequenced single mitochondria, which they noted could be used to track the development of mitochondrial disease.
The US-based team that performed mitochondrial replacement therapy publishes its approach; editorial describes its weaknesses.
