i have an idea for an update that makes ecosystems interact more with each other: mushrooms can be edited, they would have a poison system to avoid some animals eating them, they can have patterns and be poisonous for animals, or make the animal resistant to a poison type or to lower or higher temperatures but animals will evolve to be resistant to that poison type or that temperature, that can unlock new body parts that can only evolve by eating mushrooms, they spread by spores which can attach to animals and each specific amount of seconds a mushroom will grow where the animal is in that current time, mushrooms can grow mycelium that can make plants help each other, like passing water to another plant that needs it, also mushroom spores can grow into moss, a new plant type like grass that can increase a place's shallow water, which will mean that now places get dryer over time, then moss can evolve into grass or ferns and ferns can evolve onto plants. Plants will also change, making them instead of evolving seeds evolving spore droppers which are like mushroom spores, the spore droppers can evolve to drop more spores or evolve into seeds. And the last thing is a fruit growing animation, if a fruit is curved it will grow straight and then it will curve or a round fruit just growing bigger or a long fruit that gets longer, fruits changing colors while they grow like strawberries and that fruit poison is low and while the fruit gets older the poison intensity rises so animals have to eat the fruit while its still young and a sugar level for fruits that can make the fruit give more energy and body parts that make the animal more or less sugar resistant to absorb more sugar. I would like to see some or one of these features or something similar.
and also amphibian animals that can evolve from aquatic animals with special feet that can swim and walk and then evolve onto land animals or onto aquatic animals again but being able to stay more time in land, aquatic plants that are just plants that evolve back onto water and have leaves and flowers, also corals in the ocean that can evolve from algae and change color and size.
