comment How much genetic divergence must there be to yield two different species?
Besides "species" being an ill-defined term, the required genetic divergence isn't appropriately characterized by "how much" genetic change, but rather what precise genes have changed in what ways to prevent population mixing. A single gene or two might cause it, if it affects a critical function, say having to do with sperm/ovum compatibility.

comment Is hypoxia/anoxia the ultimate cause of death?
There is no one ultimate cause of death. For instance, there are neurotoxins which kill brain cells while oxygen remains plentiful, and there is complete disruption of the brain, as with a suicide-bomber.

comment Genotype of children conceived after stem cell transplant?
Infertility is common after chemotherapy or irradiation done for transplants, so the question in that case would be moot.
