A cyclical decrease in biodiversity on planet Earth every 62million years.
A plausible hypothesis. Like any viable hypothesis it needs a thorough testing, which in my opinion is a job better done by professional like the a paleontologist, micro- and
molecular-biologists.
If the hypothesis is correct, I think these periodic extinctions should exhibit a more or less a distinct and recognizable pattern. Analogous patterns, concerning the percentage of these periodic extinctions related to the overall extant biodiversity, in genetic variations, (including proportionally high mutations), a recognizable pattern in the geographical transformations and in biosphere, a pattern in distribution of water, spores and the biomass, specific effects that such recurrent CRS may induce in reproductive behaviors of some species (let us say, like plants shedding pollen at unusual times of the year, insects or other species taking the upper hand or an increased sudden evolution of new strains of bacteria or other species with short life-spans) and many more, that I probably can not imagine. Modern technology is to a large extent capable of investigating such matters. If such investigations do reveal a co-relevance, I see no reason why this hypothesis may not reflect a fact, that no doubt due to its inherent implications, coming as it does at a time, when Global Climate is a hot contested topic may at first glance, appear to be less like a routine scientific investigation and more of a propaganda, Not knowing the authors or their history I am at first inclined to be impartial and feel in no way competent to judge its viability, nevertheless hope that a thorough testing by professionals in the biological sciences would follows soon. Moreover I see no contradiction or even any direct relationship here with the confirmed and to large extent well explained facts of our planetary history. In fact the great cataclysmic extinctions induced by irregular accidental cosmic or geological events are not the objects of investigations here.
