Apparently James Cameron thinks he has discovered the remains of Jesus Christ, and will reveal all on the Discovery Channel this Sunday.  Putting aside the likelihood of this Jesus being THE Jesus (I’m skeptical, to put it midly), this part of the article caught my attention:

The human remains were analyzed by Carney Matheson, a scientist at
the Paleo-DNA Laboratory at Lakehead University in Ontario, Canada.
Mitochondrial DNA examination determined the individual in the Jesus
ossuary and the person in the ossuary linked to Mary Magdalene were not
related.

You inherit your mitochondria from your mother only – it is in the ovum before fertilization.  So doesn’t this only tell us that the two individuals did not have the same mother?  Couldn’t they have the same father? Given maternal death rates in those days, it would hardly be unusual for a lot of families to include a variety of half-siblings.  Not sure what I’m missing here.
