When will this week be over? It's been much more than a week...
Each week contains 5 generations. Each generation contains 80 species. Thus each week is 400 species long. Plus 4 to 8 landmarks and random events mixed in. We are currently in gen 147 and we started the week with gen 145, thus we will end the week with the 80th species of gen 149. In short we are about half way through the week.
Note that the name "week" is left over from the first days of project where there was only a few people on the project and everyone posted 2 species per day for a week (7 days). Sicne then we adjusted and now post many more species per generation and have shortened the number of generations from 7 to 5. The reason for this is the wiki page could not handle more than 400 species on a page so we shortened the week rather than the number of species in a generation. Thus the word "week" should really be "period" since that is what it is. Just like the Jurassic or Cretaceous Period and each generations is more like an "Epoch". Just like the Eocene or Paleocene Epoch.
