Hello and welcome to the Isla Vermanto project a (hopefully) original speculative evolution project. This is Isla Vermanto, a island thats seemingly void of all fauna with the native people and animals being seemingly wiped off the face of this island since the last ice age. Only the flora of this island is native to it. Over the last dozen millennia this island has sat off the coast of Chile waiting for something to happen, then a Multi-billionaire came along and decided to do a experiment. They would put 35 species of animals on the island and see how they evolve. Animals: 1. Common woodlouse 2. Earthworms 3. Spring tails 4. Greenhouse millipede 5. Hedgehog 6. African leopard 7. Cow 8. Rainbow Land Crab 9. Chinese giant salamander 10. Red fox 11. Sumatran striped rabbit 12. Kangaroo mice 13. Timber rattlesnake 14. Cuban crocodile 14. Yacare caiman 15. Snakefly 16. Icebug (Grylloblattidae) 17. Dead leaf mantis 18. Knysna velvet worm 19. Tuatara 20. Little spotted kiwi 21. Darwins rhea 22. Southern cassowary 23. Kakapo 24. Monito del monte 25. Quoll 26. Numbat 27. Spectacled bear 30. Tayra 31. Jaguarundi 32. Persian onager 33. Smoother newt 34. Mandarin newt 35. Common green frog
This speculative evolution project will occur over time aka there will be periods where your creature could evolve / die out (like typhon). I there will be a project that tells you when a new period is starting and whose animals went extinct (if any died out at all).
