>>5985703The Brainfruit has developed an advanced network of nutrients and hormones. The network uses its advanced intelligence to observe how individual Brainfruit perform at their given task, and then diverts nutrients from worst Brainfruit to best, essentially culling the unfit and boosting the already strong. Through this process of artificial selection, the rate at which this plant is evolving has been greatly increased, as was the purposefulness of the evolution.
Sometimes they include other breeds of Ragas in the network. While these can't contribute to the colony's intelligence, they often have other useful traits such as toxic spores.
