But logically there is opinion in what constitutes evidence. I've posted the definition from scientific sites several times over the years, and it includes eyewitness reports and other unconfirmed data, such as hair. Someday what is un-identified now may be critical evidence. Blood taken in the 1960s as police evidence is now used for DNA typing and has freed several conviced killers. Does the fact it was useless in the 1960s mean it was not evidence? No. It just means it can not be meaningfully analyised right now. Even if the hair belongs to a goat, elk, or bear, it is evidence... of hoaxing, if nothing else. But, it is evidenece.

Minimum Viable Population is usually estimated as the population size necessary to ensure between 90 and 95 percent probability of survival between 100 to 1000 years into the future. The turning point for the average vertebrate is approximately 4,000 when inbreeding or genetic variability is taken into account and not allowing for natural disasters.
It is a standard scientific model. Using estimated values does not make the concept less viable, or not applicable to certain species.
And yet you admit it is 90 to 95% effective. Not 100%, so it is still speculative. 10% is a lot of room for error.
If I was to find an Expert that said a population could be less then 4000, then what would you do? Discount him as an expert? Or, ignore the point? Or simply point out he is one in thousands? So there is no point to my looking for one now is there?

I was refering to the size of a environmental study, such as the creek and minnows, or the Counting of Snails we talked about before.

100 Iberian lynx left (it would be the first big cat species to do so since the Smilodon went extinct 10,000 years ago.)
322 condors known to be living, including 172 in the wild (pretty definitive wouldn't you say?)
Leadbeater's possum population is around 2000
the La Gomera Giant Lizard consists of 90 individuals remaining in the wild, and a captive stock of about 44 animals. This species is now only known from two separate inaccessible cliffs 2 km apart, close to the Valle Gran Rey.
Ah. Those are just the ones we know about. Who is to say that there are not 10 or 15 more Iberian Lynx? Have they used nets on every meter of their former range? I do not think so, but I could be wrong.
And words like "around" and "known" are not very definative now are they. Words like that imply that we do not really know, we are only guessing.

There is no point to it, as you have already been presented in numerous threads with various good evidences, that hint at something, but do not proove anything. To go back and list them all would be the work of hours, and since they will be casually dismissed, or shown to be unscientifically gathered, I will not bother at this time.
