While the show is interesting, I found parts troubling. They seemed to be trying to connect the "pig bomb" with the Russian boars, if just by plain association, even though there is no reported genetic evidence (as per the show) to support the supposed influx of Russian boar genetic contributions to account for the phenotypes being seen and reported as Russian boar. The problem with phenotypes is that many of the feral hog phenotypes seem to match Russian boar phenotypes and so you have people calling lots of pigs Russian boars when they are just feral.
The show also sensationalized the whole notion of the Russian boar to the point that they even identified a very large Russian boar on a game camera digital image based solely on eye shine. From the eye shine, they extrapolated Russian boar features not in evidence in the photo.
So the pig bomb in the US is tied with the Russian boar within the program, but there was no accounting for how Russian boars would be responsible for this phenomenon. Strangely, the same thing is going on elsewhere in the world, such as in Europe where the boars are indigenous. Why is the pig bomb going off over there as well? Have they had a recent influx of themselves?
While there isn't any doubt that the populations of feral hogs is growing and spreading in the US, the show was just hokey in the sense that the one aspect they needed to really substantiate several points, genetic evidence, was not in evidence for the show and so much of their claims were just suppositions.
Is the feral hog population actually getting larger (individual animal size) and more aggressive because of Russian boar genetics or is it because of a combination of feral hog phenotypes combined with a highly competitive environment. As the population grows, competition increases. One potential result is increased aggression.
It is an interesting show, but it has a lot of hype.
