Anyhow didn't Australias hundreds of thousands of foxes originate from about 20-30 originally, illegally released?

If this is the case, then foxes aren't effected by the low gene pool!

Thylacines never numbered in huge numbers when they were numorous so must have always had a small gene pool!

I always dismiss this critical narrow gene pool theory cause every species must of surely started with low numbers when they 1st evolved anyway and every species is like they are cause of their similar genes. Other subspecies evolve out of a species due to location and circumstances. Many species have successful sub species formed this way and haven't become extinct. Look at how humans have succesfully created different breeds of dogs through selective breeding and these survive to this day!

I live in East Anglia, in England, UK where we have badgers and apparently a decent sized population. Now I love exploring the Countryside especially in my local area. I'm in my 38th year yet the only badgers I've ever seen are a small handfull of unfortunate ones run over by motor vehicles.

Now I'd say for definate that England has no unexplored areas left, has a far bigger population, and is much more densely populated per square kilometre.

All the above thoeries make it more than possible that thylacines could still exist in Tasmania with a population under 1000 and be virtually undetectable. Afterall its well known thety were rarely seen when 2000+ were culled out!

Another interesting video, good discussion guys.
I think your approach of explaining the facts, probabilties and obstacles to survival adds significantly to your credibility - (Matt Moneymaker take note!)

I was under the impression that there was recently some research that has discovered that thylacines didn't have a wide range of diversity to begin with - and this is the same with the devils. This would have to strengthen the case for potentially overcoming the gentic hurdle. Interestingly, the urban legend of mainland sightings depends on the belief that there was a release of thylacines in the early 1900s (I think the original mainland thylacine being extant is just not viable)....I read somewhere, that it has been proposed that these animal were brought over - approximately 8 pairs - and it is the ancestors of these that are the mainland sightings - without some better evidence of these original ceding I would say its unlikely too. Perhaps a video analysis of the mainland sightings (or more likely the probability/sceptometer) might be an interesting short video?
Keep up the good work - eager to see your next efforts..
