Eden.

The planet was such a volcanic hell that it systematically destroyed all complex life forms by denying them the time needed for evolution. Only a few plant species achieved long term survival, by spreading massive amount of spores before volcanic annihilation.
Nineteen million years ago, some small trees developed a natural infrared sensor. These vegetable creatures used it to release their spores should one of the frequent volcanic fire threaten them. This species achieved survival. And began to prosper. Some of the offspring changed, mutated, and adapted as life always does. One of the mutation involved the emission of a small wave of ultrasound, which was a signal for all nearby trees to release its spores. Then, some other vegetable species started to rely on the ultrasound trees, with rudimentary eyes catching the spore ejection, which in turn started their own.
It took 9 million years for these plants and some others to evolve into an ant like society. During this time, the planet was getting more stable, volcanic activity was diminishing and animal life started to appear everywhere. The vegetable society had to learn to defend itself from herbivore predators. Thorns, poisonous fruits and even carnivorous plants started to appear. Several vegetable species depended upon one another to prosper. But the limited range of ultrasound signals was causing havoc. Frequently, instructions from different parts of a large nest were conflicting. A vegetable nest could be competing for vital space with another nest, or even with itself.
Around 7 million years ago, an Orchid specie evolved a limited form of telepathic transmission, which was not restrained by the ultrasound range limitation. The consequences were tremendous. While the flower spread on the planet, all nests quickly disappeared and merged into each other. As a matter of fact, the node was composed of two levels, the first one was the most basic, the multitude of vegetable consciousness that was busy keeping themselves alive on a day to day basis, with as much awareness as most earthlike vegetables. But, as the old terran saying, a team could be much more than just the sum of the teammates' capacity.

"Indeed."

The network of linked vegetable was much more than a larger node, as in effect, it created a consciousness. It took only a few thousand years for the Master Node to evolve from an instinctive intelligence to a sentient one.

"We are one."

Reportedly, this was the first thought of the newly formed collective mind. From then, began a long period of physical stagnation. But on the mental point of view, the Mind was a fury of thought. Subjects on scientific, mathematics or philosophical grounds were explored. But always on a theoretical point of view. As the Mind lacked any way to interact with its surrounding, any practical study was out of his reach, but that did not bother it, as it had little use for experiments.

"Then came the Hammer."

The Hammer took the form of a wandering asteroid which fell on Eden 6 million years ago. The northern continent was badly hit, but the nuclear winter that followed almost wiped out the Collective Mind. Several of its constituent species could not survive the century of reduced luminosity, nor the overall lower temperature. Luckily, the Mind discovered that some seeds could survive the cold for this long. When the cataclysm's effect slowly faded, the Mind was fully aware it had come very close to disappearing. The notion of death, which was only a distant possibility a century ago suddenly became a threat.

"What was that ? Where did it came from ? Will it come back ?"

These questions needed answers. As soon as its survival was assured, the Collective started to devise his course of action. To work out that problem, the Mind would need to interact with its surrounding. Some particular trees were bred, associated. The Mind could not modify the DNA sequences of its components, it was just breeding some species and trying to obtain the desired results. But it had time for itself. Three thousands years ago, after countless failed experiment, the Mind achieved a result : the fruit of a certain tree, once fallen would follow a predetermined path with rudimentary legs, and perform a simple action before burying itself in the earth. That simple tool enabled the Mind to create dams and irrigation systems. But more than that, it added a whole dimension to the Collective's actions. These first tools were used to create more efficient tools, which were in turn used to.......

"Today."

After the first fruit-tool, the slow pace with which the Mind viewed time had to change. When born, the Mind was perceiving time by the passing of seasons. After the Hammer, it switched to the passing of days. After the first fruit tool, it subdivided days in 9 time units, each time units being divided in 9 sub-units. Most of animal species had been disposed of, and the remaining were absorbed by the Mind as tools. The planet was completely acclimated, a garden in which no predators lurked. The mind had established full control on the ecosystem, and most of his duties were to respond to the problems of supply and demand. When a component of him needed something, the Mind checked what or who could fulfill it, and arranged the transportation of the goods where they were in need. The main subtlety was to establish priorities between demands should a bottleneck of production or transportation arise. The sky is regularly filled by Zeppelin like plants which transports goods and sub-species from place to place on the behalf of their Master Mind. Due to his level of understanding and exploration of the solar system, the Mind does not fear the Hammer anymore, it has the power to prevent it. But an irresistible force is pushing it out of his birthplace, even out of his own solar system. Something that was absorbed with some animal tools long ago.

Curiosity.
