Food For Thought: Chaos Theory
"Chaos theory" is the theory of
the branch of mathematics that deals with complex systems whose behavior is highly sensitive to slight changes in conditions, so that small alterations can give rise to strikingly great consequences.
Actually, concerning Great Lakes Earth, ~TheHarpyEagle (https://www.deviantart.com/theharpyeagle) had this to say:
I believe in parts of it but also think given the infinite fractal nature of the multiverse that great differences in origin can still have very similar results.
So which POD would make big enough deals to bring up chaos theory?
One: An Earth in which the Snowball never happened
Sorry, that is a conspiracy by the Anomalocarians.

The Three Elements of the Milankovitch Cycles
According to the Serbian geophysicist Milutin Milankovitch, there are three elements that make an ice age possible:
Eccentricity (orbital shape): Varying between 0.000055 and 0.0679 over the course of 100,000 years (1.0 being a perfect circle).Obliquity (axial tilt): Varying between 22.1 and 24.5 degrees over the course of 41,000 years.Axial precession (change in the orientation of the rotational axis on a rotating body): Polaris being the North Star for a total of 26,000 years.
The question is how connected those three elements are, in the event someone wants to change the numbers in a worldbuilding process to make either a longer or short

Food For Thought: Permian Extinction Event
Great Lakes Earth had often been criticized for the "smaller" Permian extinction event, simply because I had killed off 80% of all life on my alternate Earth at that time.
But was it really smaller? We may need to dig deeper in the math.
252 million years ago, back home, it's been said that 70% of all terrestrial species and 95% of all marine species had become extinct. These numbers were placed separately, which means we are not looking at the total amount. Out of 100 terrestrial species, 70 were gone. Out of 100 marine species, 95 were gone. That is 165 species out of 200. Divide that by each other, and you'd get the grand total of
