Quite sure, actually! You'd have to isolate different dollops of poo (for example) and do the statistical thing based on RNA density per dollop, normalised to the population size of the area being analysed (forgive the intended pun)!

This would be statistical heaven never mind meat and drink for the journalists. Even the woke would be able to feed on that and I hope they do!
