strong evidence to prove that the mitochondria once existed as a free-living bacteria‚ and were engulfed by the primitive ancestor of eukaryotic cells in a arrangement called endosymbiosis. Mitochondria have evolved over thousands of years‚ but still share characteristic with bacteria such as: their genome is a circular molecule ‚ have little non-coding DNA‚ and have their genes tightly packed with few intergenic regions between genes. Furthermore‚ mitochondria are organelles that contain a separate
