For this purpose, invasion probabilities and extinction times of single mutations do matter, but are not sufficient metrics on their own.
The techniques is applied to deterministic systems, and it is our belief that such system are important for modeling purposes, although analysis of extinction phenomena, such as tumor eradication, may require stochastic factors to be considered.
And the influence of environment begins, critically for the purposes of de-extinction, in the womb.
It is hard to fathom in this era of more-is-better, but for about a decade before Coughlin came along, the all-purpose swimmer was close to extinction.
Biotic assessments are increasingly carried out to detect NIS (Gravili et al. 2013; Katsanevakis et al. 2013), and might be used also for the purpose of testing hypotheses of putative extinctions.
The ultimate purpose, it has been claimed, was the extinction of Aborigines as a distinct race.
