In her Sasquatch Genome Project Dr. Ketchum claims that the mitochondria found in her sasquatch hair samples is human. Something tells me that her assumption is erroneous. As far as I can see mitochondria really has no reason to evolve, given a consistency in environment. Something tells me that different animals share mitochondrial species, which they inherited from a common ancestor. This would appear to be true of human and sasquatch/yeti in so far as both animals share a common type of environment.
Is there any work out there regarding the inheritance of mitochondria? Are the different species of mitochondria shared among the different species of eukaryote?
