Devónico

The Devonian is the novel’s deepest point of return: the period in which the first amphibians appeared becomes a way to think about evolution, human consciousness, and whether the past can acquire purpose only in retrospect. For the narrator, it is both a scientific reference point and a provisional beginning to a story whose origins keep receding—from the first vertebrates onto land to the creation of time and space.

Evolutionary Background

The narrator introduces the Devonian in a letter to Vera, explaining that understanding his account of Ana and José requires going much further back in time. In his view, the story begins when the first amphibians appeared. That claim gives the period a double role: it marks a stage in vertebrate evolution, but also establishes the immense timescale against which the narrator’s personal story will be considered.

His account of Taveuni makes the evolutionary sequence unusually visible. The island’s vertebrates include fish, frogs, lizards, birds, bats, and Fijians; the narrator presents this relatively simple range as a nearly transparent image of vertebrate evolution, from fish to amphibians, reptiles, and eventually birds, bats, and humans. The Devonian stands at the beginning of that sequence, when amphibians first moved onto land. The novel later returns to this emergence not merely as a biological milestone but as a past whose significance can be seen from the far end of the evolutionary path.

The narrator’s own place in that history is precarious. Reflecting on the chain of reproduction that leads to his existence, he imagines a Devonian amphibian among his many millions of predecessors. If even one ancestor had died before reproducing, he would not now be sitting on the porch in Taveuni. The period therefore figures not only as a distant chapter in natural history but as one link in the contingent chain that made the narrator possible.

A Dispute over Evolution’s Meaning

At Taveuni, José challenges the narrator to consider whether evolution has been driven only by random mutations, or whether questions of intention and purpose also deserve consideration. The narrator initially gives the conventional scientific account. He describes natural selection as the process by which individuals with small advantages are more likely to pass on their genes. José’s questions unsettle him, however, by pressing on what such an account explains—and what it leaves open.

José argues that human consciousness is not merely an arbitrary trait selected in the struggle for existence, but may be the purpose toward which the process tends. He points to capacities such as sight, flight, and upright walking that have developed repeatedly in the history of life, and proposes that nature may also be moving toward an intellectual, comprehensive vision. The narrator resists this interpretation: as a biologist, he had learned to set aside the idea that evolution has a goal, even though as a child he had entertained similar thoughts under the influence of Pierre Teilhard de Chardin.

The exchange distinguishes a mechanism from a meaning. The narrator can describe mutation and selection without conceding that evolution is directed toward consciousness. Yet José’s question about how rudimentary wings could benefit an organism before they were useful presses on the difficulty of explaining every evolutionary transition through an immediately evident advantage. The novel stages the tension rather than resolving it into a simple proof of purpose.

The Devonian as Retrospective Perspective

John turns the Devonian into an argument about how historical meaning depends on where one stands in time. He asks the gathering to imagine witnessing life on Earth hundreds of millions of years ago. The narrator describes the late Carboniferous, when the climate was becoming drier than in the Devonian and early Carboniferous, early flying insects and reptiles were developing, and amphibians still dominated terrestrial vertebrates. John’s point is that observers in such a world might have judged life absurd because its later possibilities had not yet become visible.

For John, purpose may take time to flower. The present generation may be at the vanguard without having reached any final destination; only beings living a hundred, a thousand, or a billion years later might know where the process was going. In that account, the future can become, in a qualified sense, the cause of what happens now—not a cause in the narrator’s ordinary backward-pointing sense, but the standpoint from which earlier stages can be understood as leading somewhere.

The narrator objects directly that a cause cannot belong to the future. John answers by turning the perspective around: had terrestrial life not developed beyond its earliest stages, no one could have declared its apparent lack of purpose. The point is not that later consciousness proves a predetermined evolutionary plan. Rather, the novel asks whether a history can become meaningful through the arrival of a consciousness capable of recognizing and interpreting it.

A Beginning That Keeps Moving

In a later conversation, the narrator is asked to return to the Devonian. He answers that he sees the first amphibians. The reply allows the earlier debate to be recast: had anyone witnessed life four hundred million years ago, it might have appeared to be a monstrous display of absurdity, but human consciousness now reads that era as a prelude. Without the tadpoles of that time, there could have been no consciousness of life on Earth, either before or after them. Meaning here is retrospective and relational: the later observer does not erase the earlier life but makes its place in the larger history perceptible.

The narrator rejects the claim that humanity is therefore the measure of everything. He says that human consciousness now decides what has meaning for human intellect, while the formation of the solar system once appeared to its observers as a nauseating process and only later became legible as a prelude. The history of the solar system, he suggests, bites its own tail: those who arrive late can recognize the beginnings that could not recognize themselves.

This circular structure links the Devonian to the novel’s other temporal beginnings. The narrator observes that events might have begun in many places, including Taveuni, Oslo, Salamanca, Marseille, Cádiz, or Seville; from a broader perspective, the most fitting beginning is the Devonian, when the first amphibians came onto land. Yet the beginning can be pushed further back, to the Big Bang, when time and space were created. The applause for that explosion, the narrator remarks, came fifteen billion years later. The Devonian is consequently neither a final explanation nor a merely remote date: it is a hinge between evolutionary contingency and the later consciousness that looks back and gives the past a shape.
