Poop or GTFO

Another yeti thread. Three points:

1) Breeding populations must be large to sustain a species, particularly one with a primate's slow reproductive cycle. If there is a stable breeding population, it usually must number in the thousands for the species to avoid extinction. So this idea that there are a few dozen yetis living in a remote region is simply nonsense - there need to be a couple thousand of them in close proximity to one another, or the species goes extinct in short order.

2) Someone's seeing something. Shipton and Messner weren't lightweights, or given to telling tall tales. Messner wrote a book offering a rational explanation, which has, of course, been ignored.

3) As is so often the case, everything depends on poop. If yetis exist, they must eat. Since they're big, they must eat a lot. And, if they eat a lot, they must poop a lot. So let's see the poop! We're up to our eyeballs in "eyewitness accounts" and footprint casts. But no yeti poop as far as the eye can see.

To paraphrase Descartes, it does not poop, therefore it does not exist.

Now the sasquatch, that's a whole different thing.

Next week: where do yetis go when they die?
