[Speaker for the Dead] How does the "Third Life" of a Pequenino work?

Particularly, I am interested in the xenobiology of how the individual Pequeninos can retain memories in its father-tree state, and how it can interpret or sense its surroundings. Do the father-trees have a central nervous system? How do they know how to turn themselves in to tools, and by what mechanisms do they do it?

Father trees do not give themselves up for making tools, those are brother trees (trees that grew from pequeninos who were not planted but rather fell on the field of battle, they are alive but retain no consciousness).

It is not known how father trees retain the memories from their Second Life. It is hypothesized that the Descolada is responsible. Before it was eradicated (or eviscerated, as some would contend) and replaced with the Recolada, Lusitania's xenobiologists discovered that the Descolada actually communicates among itself by distributing packets of genetic information which are picked up by other Descolada bodies.

Although these packets were not decoded, it was noted that occasionally the reception of these packets would cause the receiving Descolada body to rewrite itself to incorporate the information contained in the packet. It was theorized that by this method of communication, the Descolada was able to facilitate the pairing of species on Lusitania and actually enable the Pequeninos to experience the Third Life.

It was also found that without the Descolada, a Pequenino carried into the Third Life would have no consciousness, memory, or sentience. Planter, the Pequenino upon which the experiment was carried out, is the only brother tree given the honor of retaining his name.
