Of course we have sunspot cycles, minor and major ice age cycles, meteor impacts, super-volcano eruptions, earthquakes, plate tectonics producing subduction and uplift, and, of course, weather pattern changes to supply all that environmental pressure.

And then there's all those evolving predator-prey relationships, bird/insect plant symbiotic relationships, foliage changes, the arising of grasslands and the spread of deciduous trees, and that's only the tip of an enormous iceberg of other environmental changes.

Yup, all true, and one of the major reasons why evolution is totally false. Look at all those changes, just look at them. How many of those environmental changes give thousands or millions of years of warning - not a one. If the species was not able to adapt to those changes beforehand it would not survive. When a crisis occurs, there is no time for mutations, gradual evolution or any such thing for one very simple reason - the dead do not procreate.

It's truely amazing that there haven't been any mass extinctions.

Of course. You are describing natural selection.
