It is an incredible breakthrough and if it prevents disease then all well and good, but are our Administrative Systems set up to handle such an arrangement?

[maxerickson]

Sure. The mitochondrial donor can be treated as a source of tissue and you are all done.

I really struggle why we keep maintaining some archaic definitions around the “family unit” anyway. So someone has 3 parents instead of 2 - nothing wrong with that.

[drekipus]

It's ok to not know why something is.

My daughter doesn't know why we have archaic laws around seatbelts either, but she's 3.

[progbits]

This makes no sense.

The seatbelt laws are not archaic by any meaning of the word, and they can be justified with rational arguments.

Care to try doing the same for family thing? Aside from tradition.

It's not that hard to imagine a rational argument where humans have evolved to grow with one or two parents, leading to all sorts of psychological prewiring.

(I'm not supporting the argument, just saying that it's not hard to come up with a plausible rational one)

The modern nuclear family is, well, modern. Children were collectively raised in most cultures. (Certainly almost all that gained prominence.)

Before DNA testing nobody could tell anyway.
