History of Nispe

This page serves to explain Nispe's history, both from the planet itself and it's inhabitant's perspective.

### **Cloacian (Approx. 2.70 Billion Years)**

The start of the cloacian coincides with the birth of the very planet, circa 2.39 bya. the planetary evolution of nispe was similar to earth in this regard, including, at around 200 my after formation, the impact of a smaller celestial body, which partly disintegrated; while most of the impact's mass went to the planet, some remnants of the original planet went into the formation of one of the moons, the biggest, while some detritus consolidated into a second smaller one. as nispe solidified, the first water bodies started to form from the dense vapors in the atmosphere, and around 500 my later the first lifeforms emerged, possibly from a panspermic event coming in contact with the massive underwater calderas of the time. at around 900 mya, the first photosynthetic organisms appeared on nispe, filling the atmosphere with oxygen and triggering a snowball event: but, due to the relatively far distance from it's sun, this period lasted for a very long time (circa 400 my), in which almost every nispean lifeform was killed off and relegated to the thinner ices on the equator, until the passage of a jovian giant, which had ben relocating to a new orbit, moved out nispe enough to get it closer to the sun without exiting fully it's orbit. as the so called "snowball nispe" period came to an end, life returned to evolve, eventually giving rise to the first multicellular lifeforms 100 my later.

### **Benician (Approx. 140 Million Years)**

The first era of complex multicellular lifeforms started effectively with the evolution of the latter, marking the boundary between the previous era. during the first millions of years, nispe also reaches it's maximum close to the sun ever, allowing life to flourish under these new, much warmer conditions. during this time, the ancestors of all the species that eventually formed the first food chains, from the spike lettuces to the fishworms, evolved. along with the lettuces, photosynthetic organisms eventually managed to reach an all-time high temperature for the planet, as the production of oxygen reached a notable quantity amongst the atmosphere's gases, of 25° on the surface, which also caused, for the only time in nispe's whole history of life, the total disappearance of ice sheets altogether from the planet. for the next 60 millions of years, life continued to evolve, giving rise to new biomes (like pillar forests and fan reefs) and even whole new genres and clades like the xenicthyans, fish-like pseudovertebrates evolved from radial ancestors. but eventually, this warm period of nispe started to end as 240 mya nispe started to realign to it's original orbit. shortly after, ice sheets started to reappear in the poles, bringing in also a local mass extinction on the lower-depht biomes such as the low-tide gardens.

### **Chodician (Approx. 87 Million Years)**

The next era on nispe's history of life didn't coincide, despite common belief, with the B-CH Extinction event that disrupted many environements on the planet, but with the formation of an ozone layer, a few millions before that, which would in the future allow for the evolution of terrestrial life. appearing 150 mya, the first land lifeforms consisted of a totally new lineage of chromistids evolved from the algae colonies left behind, along with the dried-up pillars of pillar lettuces, during the sea level decrease. with the formation of large, pole-covering ice sheets, a vast amount of zooplankton transported by these currents allowed for the formation of a rich coldwater ecosystem, while the middle sea, left isolated by river reflux and contrasting currents, developed it's very own biomes, some species of which would go on to colonize the fresher waters upwards. later on, 40 my after, a lineage of amphibious shore-dwelling nispochordates and lettucegrasses started to colonize the beaches and the nearby rivers, launching the evolution of the most succesful animal and plants lineage of the period, which would culminate in the highly evolved succugrasses and keramouths. meanwhile, on the east coast of panspermia, descendants of the sea balls start to colonize every environement, including land by considering swamps and estuaries, facing a massive success; however, their very characteristics also had an extremely harmful impact on the already estabilished environement, to the point of effectively extinguishing any other species of plant in the zone along with many of the animal that once inhabited these biomes.

### **Orchidian (Currently 72 Million Years)**

The Orchidian, which sees the affirmation of the Xenicthyans on the seas and the Rostrilians on the land as the dominant lifeforms, was kickstarted by the collision with the planet of a 6 km-wide iron meteor, near the shores of east Panspermia. shortly after, the supercontinent of Labia also forms, creating new, enormous mountain ranges and engulfing the Middle Sea, turning it into an ecologically isolated lake. but most importantly, the orchidian also sees the realignment of nispe on it's original orbit, albeit slightly destabilized. this creates massive ice caps on the poles, as well as cooling the planet's surface considerably, with only the equatorial belt free of cold seasons. a new developing fault is also found on Holea, which develops as it connects the Great Eastern Lake and the middle sea, as well as creating numerous waterflows down on the side of the western mountain ranges. meanwhile, life is divided in the oceans, as labia creates an unsurmontable barrier between the northern and (reducing due to the ice caps) southern ocean ecosystems. despite this, life greatly variegates in this first half of the era, as new niches are created both on land and on water. however, towards the end of the Orchidian's first half, a short-lived but deadly ice age destroys the equatorial and sub-arctical ecosystems all across the world.
