Episode: Mitochondria Genetics & Human Metabolic Variation in Health & Disease | Douglas Wallace | Episode 283
Description: Send us Fan MailMitochondria in human evolution, climate adaptation, maternal genetics, aging, and disease.TOPICS DISCUSSED:Endosymbiotic theory: Mitochondria arose from oxidative bacteria engulfed by archaea-like hosts, confirmed by phylogenetic analysis.Maternal mtDNA inheritance: Mitochondrial DNA is inherited from the mother, not the father. There are adaptive reasons for this.Haplogroups & adaptation: Tropical lineages tightly couple energy production for efficiency; northern ones uncouple to generate heat.Heteroplasmy & aging: Mixed mutant and normal mitochondria accumulate in cells, eroding energy in high-demand tissues like brain...
