[edit] Evolution

Most of the life of the planet appeared in the dark and acid environment of the caves, that it's constant during all the year (it doesn't have extreme changes between the summer and the winter in Ebarkhara).

[edit] Kraibee

This is the old ancestor most similar with current arackrabees. It descends directly of the Swareds, those creatures described previously as having the body segmented and for being very poisonous. As well as the Redirea, the Arackrabees descends of the Swapidlers, the "aquatic spiders".

Kraibee

The Kraibee appeared when some Swapidles had started to leave the water and had needed to develop longer legs to be able to walk with bigger easiness. In this process, the last segment of its body increased very of size and lost the legs (they become very small, not having more function). Its feet allow that it scales and arrests it the walls, activity that cannot be executed by its relatives, the Redireas. It still poisonous, most of the poison started to concentrate in the forebody of the body.

Small orifices had appeared in its coasts and allowed that the animal perceived some vibrations in air, a primitive hearing. The most radical change was in relation to the eyes. From the five small eyes only remained the two frontals, that had originated small antennas to look over the tentacles (an modification of the mouth of the Swapidler). The Kraibee is onivorous but it feeds mainly of other animals.

[edit] Beerack

The life in the caves was not far from easy. Many were the predators and the existing competition. With this, the Kraibee started to leave the cave during the summer, starting to feed small fruits. With the time it acquired a small plumage in two of its pairs of legs, that with the time origined primitive wings that the creature raised for the high to allow to be carried by wind for short distances. The animal became smaller and lighter, substituting the strong exoskeleton for a soft skin, but resistant. The antennas had been prolongated and allowed that it was percipient to the movements that occurred around it. The auditory sensors of its coasts had become more sensible the sounds and had been covered by a small membrane to protect them of the variable ambient, originating the Beeracks.

Beerack

The Beeracks had developed more suitable legs to the scaling and the manipulation of some objects, having started to leave the caves in small groups, being originated primitive societies. In these societies, the strongest creature was chosen as leader and all the decisions of the group would have to pass for its assent, together with the female of better prominence. Small nests had been constructed in the external side of the cave and, with the time, these animals had needed to search something bigger to support the great growth of each group. Small genetic variations in the individuals of these groups had started to appear, being selected only the Beeracks whose change could guarantee its survival.

These mutations had been transmitted for all the population until arriving at a point where all loaded the responsible genetic material for its different forms, revealing only one of them. The female of bigger prominence increase its size and passed then to be responsible for laying all the eggs that expressed different characteristics and that they had originated different creatures, revealing characteristic determined for the genetic material found in all the population, but revealed only for these groups. With the time, only some variations had been selected, originating the first societies arackrabees.
