In Cook's chapter entitled, The Nevada Conference, he lists a group of "New Postulates" related to Saturn's historical interactions with our current solar system. This history differs from that presented by Talbott and Thornhill. This is the chapter from which I quote:

1) Earth, Mars, and Neptune (and possibly the Moon) were all planets (satellites) of the star Saturn, and had been orbiting Saturn for billions of years since their creation when, shortly before the Cambrian, 560 million years ago, Saturn intersected with the Solar System -- perhaps for the first time.

2) Saturn swept around the Sun like a comet, to return every 26,000,000 or 27,000,000 years, still with the original planets in tow.

3) Over time, some of Saturn's planets were captured by the Sun. This happened to Earth after the Permian, 250 million years ago.

4) The return of Saturn at 27,000,000-year intervals was responsible for the periodic extinctions which the Earth has experienced since the Cambrian. On traveling through the plasmasphere of the Sun, Saturn would attempt to discharge to any nearby objects, including, of course, Earth. (This would be true whether Earth traveled with Saturn as a satellite, or Earth was already orbiting the Sun.)

5) Extinctions were thus most likely to have been caused by an initial electrical repulsive shock followed by massive electrical discharges (arcing) from Saturn when at or near perihelion in its path around the Sun.

6) The specificity of the extent of many extinctions can probably be attributed to the different locations of the strike point of the arcing from Saturn (on land, shallow sea, or ocean), and the fact that at different times the contact would have varied with the chance location of Saturn and the position of Earth.

7) It might even be suggested that plasma discharges to Earth decreased over time, being perhaps massive at the start of the Cambrian, then lessening sporadically, with another large hit (so to speak) at the end of the Permian.

8) Saturn may have been responsible for the development of all life (speciation) after the Cambrian, and especially the complex species which have developed since that time.

9) Speciation probably took place during or after every extinction period, although it might have taken many thousands of years before new species stabilized and would show up in the record.

10) The fact that Saturn was never deflected by the Solar System planet Jupiter would be explained by the fact that in 560,000,000 years Saturn would have entered the Solar System only 19 or 20 times.

11) Once the period of Saturn was significantly reduced at 6 or 3 million years ago, bringing it closer to the Sun more frequently (of which we have both physical and written records), smaller planets of the Sun would have a much greater chance of being captured into a sub-polar or supra-polar orbit by Saturn. This is the only stable location for planets which encounter Saturn on its periodic sweep through the inner region of the Solar System. In fact, it would be likely that over time all the smaller inner planets would be captured in this manner. Only planets further away from the Sun would be safe from this because they would be less likely to encounter Saturn.
