This should resolve as soon as an eukaryote is known to be de-extincted.

Resolution citeria:

• A single organism or a descendant thereof must be alive at least 2 years after the first live ancestor cell (e.g. not something like the temporary de-extinction of the Iberian ibex in 2003).

• The organism must be considered to be a completely developed individual of its species (e.g. not something like cultivated dodo muscle tissue).

(I am not sure how to improve the last criterion.)

Please suggest taxonomic ranks lower than tribe.
