All 41 Evrima Mutations and What They Do in The Isle

Mutations are traits your dinosaur gains as it grows in The Isle Evrima, a survival game where you play as a dinosaur. Each one changes something about your animal, like how it heals, how it handles thirst, or how it sees at night. Once picked, a mutation works on its own for as long as that animal lives.

What Are Mutations in The Isle Evrima?

Mutations fall into three groups. Universal ones are open to most dinosaurs. Herbivore and carnivore ones are tied to what your animal eats, with omnivores sharing the herbivore list, and unlockable ones stay hidden until you complete a task in the game. Much of the game comes down to staying fed, watered and healed, and mutations let you get better at the things your animal struggles with most. That's why they matter so much to how your dinosaur survives.

How Mutations Are Chosen as Your Dinosaur Grows

Mutations come in as your animal grows. A juvenile gets its first pick, a sub-adult gets its second, and a full adult gets its third. A fourth slot is tied to the Elder system. At each point, you choose from the options you're offered, and those options depend on your species, your diet and the slot you're filling.

Your picks last for that life, so it helps to think about how you'll play before you choose. A hunter chasing prey and a grazer feeding on plants will need different help.

Why Diet and Sex Limit Your Choices

Universal mutations are open to most dinosaurs, though a few are limited to one sex. Herbivore and carnivore mutations are only offered to plant-eaters or meat-eaters. Many mutations link closely to food and water, which is why diet matters so much. A carnivore can restore thirst by eating corpses, and a herbivore can get water back from its plant meals.

How to Unlock the Special Mutations

Unlockable mutations don't show up by default. Most have to be earned by completing a task in the game, such as jumping 50 times for Reinforced Tendons or eating bones while you have a fracture for Osteophagic. Once you meet the requirement, the mutation joins your options for a set slot. Some of these tasks are also limited by diet or sex, so only matching animals can take them.

Entombing Carries Mutations Into a New Life

At full growth, you can entomb your dinosaur. The animal's current life ends, and you restart as a juvenile of the same species. Your mutations come with you and grow stronger with each entomb. Entombing is how you build up one line of animals over several lives.

FAQ

Do mutations stay after my dinosaur dies?

Death sends your dinosaur back to the start of growth, and the picks you've made last only for that life. Entombing is the step that carries them forward.

Why don't I see some mutations other players have?

Server admins decide which mutations are switched on, and they can change how strong each one is. A mutation can be missing from one server or work differently on another, so the options depend on where you play.

Can mutations be passed on to offspring?

Some can and some can't. Hatchlings can inherit certain mutations from their parents, and those inherited ones fill their own spots, separate from the picks you make while growing.
