Corrections

• While Branford Marsalis was band leader for the tonight show for three years, I can't find evidence of Wynton ever even appearing as a guest, let alone band leader.
• I was thinking about the book 'Seven Daughters of Eve'. There is apparently a single unbroken female line to one woman who lived in Africa one or two hundred thousand years ago.
• According to wikipedia, a recent article indicated mitochondrial recombination was possible. My brother is doing work on related stuff, I think - perhaps he has some insight? Also, I'll have to ask him about polar body twins, which sounds sort-of impossible to me, as well.
• Methane is odorless, but, like propane, packaged with a foul smelling gas to indicate danger.
