What Inspired the Geography of Great Lakes Earth?As an alternate Earth, it makes sense that pretty much everything is inspired by Earth itself. Not just that, but primarily Earth as it used to be, because plate tectonics actually make Earth rather flexible. Its history is so diverse that it makes it easy for me to experiment with an idea of putting those past features into the present day.
The term “supermoon” actually means that the full or new moon has reached its perigee, or closest point of orbit, giving us the illusion that the moon has grown bigger. Despite that truth, the term used in the news headlines has a certain kind of appeal for an experiment. Even though our moon is the largest in proportion of its parent planet, it is not the largest moon period. Our gas giants — Jupiter and Saturn — have t
Author's Word on Great Lakes EarthSince its four and a half billion year history, the face of planet Earth had been constantly changing. Textbook examples—like Rodinia, Pangaea, Laurasia and Gondwana—are features of what happened. These are broad examples of history, the knowledge of what really happened. But for a while, there is a genre of its own right, alternate history, the knowledge of what would have happened had the greatest moments in history taken the other direction. Scholars had long speculated on how the big things in human history would have changed, like what would happen if America lost the Revolutionary War, or if the South won the Civil War.
I have read a few alternate history scenarios myself, but they all have one thing in common, for me, at least—Earth is still the Earth we recognize.
In my neverending strive for original directions in already-told stories, my mind buzzes with the one strategy of alternate history that hasn’t been used either be

Back home, there are an estimate of 80,500 species of chordates covering only three percent of the animal pie chart. On Great Lakes Earth today, there are still 80,500 species of chordates, but now taking up only half of one percent of the pie chart. Back home and on Great Lakes Earth, another 80% of the pie is reserved for one phylum—Arthropoda. To understand how this could be, let us rewind 444.4 million years, in which life on Great Lakes Earth, over 150 million years after the Cambrian Explosion, witnessed its first and worst mass extinction. 90 to 95% of all life perished in a combination of carbon excesses from the flood basalt eruptions of Terra Australis (Sahul and East Antarctica); rogue algal blooms that robbed the oceans of oxygen, suffocating them and a 25-mile-wide ball of pure iron slamming into what we’d call easter

The reefbuilders of Great Lakes Earth are very alien compared to ours back home. For starters, Anthozoa, the class consisting of corals and sea anemones, have been extinct for 444.4 million years. Also on the hitlist were Archaeocyatha (believed to be poriferans) and Paracrinoidea (primitive sea lilies). In their absence, crinoids, blastoids, edrioasteroids, sponges, barnacles, bivalves and fan-head worms took the opportunity. By 65 million years ago, only the latter three remained. The bivalves did not suffer a noticeable loss as a whole back then, but Hippuritoida, the rudist order, suffered a 64% loss in diversity before becoming extinct entirely as recently as five million years ago.
In tropical waters, within the confines of Cancer and Capricorn, the only reefbuilders you would find were Canalipalpata, the fan-head worms. In waters so poor in nutrients,
