How fast the world went from "one big block of land" to the configuration they are working on makes a *big* difference.
The "big block will have coastal regions with lots of diversity, but the interior will be like the Australian Outback or worse. *nasty* desert.
Once the rift forms, you'll get plants and animals from the old coasts spreading up the new coasts. which will make for some "odd" distributions, and lots of species having to adjust to new-to-them ecological niches.
Weather and climate on the new sea coasts will keep changing as the sea grows.
Given "normal" geological processes, the effects will probably be well over by the times they'll be writing. But if it happened faster?
