Jubilate amphibio


Chapter 1: Axolotl

page 9: Loren Eiseley...a profound shock at the leap from animal to human status. An article about Julian Jaynes, There is only awe, records that he described the muting of the gods as an excruciating loss from which humans still have not recovered:
The mighty themes of the religions of the world are here sounded for the first time. Why have the gods left us? Like friends who depart from us, they must be offended. Our misfortunes are our punishments for our offenses. We go down on our knees, begging to be forgiven.
page 15: great amphibian extinction. The rare Archey's frog is among those holding on thanks to captive breeding. The Gastric brooding frog may be the first animal to be de-extincted

page 22: new limb: organs and teeth too. 
 
This is the second in a new series of notes and comments on chapters in The Book of Barely Imagined Beings. It appears around the time of the US publication, and adds to an earlier series , which included In praise of error...and elephantsFire within and Conquest, regeneration, hidden things and which appeared around UK publication.

Conquest, hidden things, regeneration

Sixth in a series of notes and comments on The Book of Barely Imagined Beings

Chapter 1: Axolotl

page 18: there is an error in the printed text of the UK edition.  The correct name of the environmentalist and philosopher mentioned in the marginal note is Paul Shepard.

page 18: the high point of European global expansion and conquest. See a recent comment piece by George Monbiot: Colonised and coloniser, empire's poison infects us all.

page 20: contemporary accounts are harrowing. A short passage edited out of the book refers to a story that has fascinated me since I first came across it more than 25 years ago: La Relación by Álvar Núñez Cabeza de Vaca, first published 1542 and available in a 1986 English edition as Adventures in the Unknown Interior of America. (There is still, inadvertently, a reference to it in the bibliography.) Shipwrecked on the coast of Florida in 1528, de Vaca was one of three men, from an expedition of more than three hundred, to survive. He walked all the way to Mexico in search of other Spaniards. It took him eight years, and on the way he was, first, enslaved and, later, made his way as a trader and shaman famed for his powers of healing. De Vaca developed something like sympathy for indigenous people that was rare among Europeans. His account of the first traces of other Spaniards after nearly a decade in the 'wilderness':
We traveled over a great part of the country, and found it all deserted, as the people had fled to the mountains, leaving houses and fields out of fear of the Christians. This filled our hearts with sorrow, seeing the land so fertile and beautiful, so full of water and streams, but abandoned and the places burned down, and the people, so thin and wan, fleeing and hiding; and as they did not raise any crops their destitution had become so great that they ate tree-bark and roots. Of this distress we had our share all the way along, because they could provide little for us in their indigence, and it looked as if they were going to die. They brought us blankets, which they had been concealing from the Christians, and gave them to us, and told us how the Christians had penetrated into the country before, and had destroyed and burnt the villages, taking with them half of the men and all the women and children, and how those who could escaped.
In A Field Guide to Getting Lost, Rebecca Solnit notes Eduardo Galeano's observation: "America was conquered but not discovered."

page 21: continued survival. See Mythic Salamander Faces Crucial Test: Survival in the Wild . "In their only home, the canals of Xochimilco in the far south of [Mexico city], the axolotls’ decline has been precipitous. For every 60 of them counted in 1998, researchers could find only one a decade later." (Added on 31 Oct)

page 22: regenerative biology. A huge topic which I will not go into now. Among recent general articles on the topic are these:

Chapter 1: Axolotl

page 2: The 1952 story by Julio Cortázar is here (and interpretative notes are here). The Tasmanian author Richard Flanagan repeats the human/creature switch in his 2001 novel Gould's Book of Fish, transforming the narrator into a Leafy seadragon.

page 3: 'The Axolotl is kind of salamander and a member of the family Ambystomatidae, which is endemic to North America. Another family of salamanders, the Plethodontidae, are also mostly found in the Americas but some species in the family are indigenous to Sardinia and Korea (!). Plethodontidae have no lungs and are also known as Lungless salamanders. The respire through their skin and the tissues lining their mouths. Like chameleons and frogs, some Lungless salamanders have tongues that act like a tethered projectiles.

page 7: In The Rings of Saturn, W.G. Sebald writes:
...because of the immense weight of the impediments he is carrying, [Thomas] Browne's writing can be held back by the force of gravitation, but when he does succeed in rising higher and higher through the circles of his spiralling prose, borne aloft like a glider on warm currents of air, even today the reader is overcome by a sense of levitation. The greater the distance, the clearer the view: one sees the tiniest of details with the utmost clarity. It is as if one were looking through a reversed opera glass and through a microscope at the same time. And yet, says Browne, all knowledge is enveloped in darkness. What we perceive are no more than isolated lights in the abyss of ignorance, in the shadow-filled edifice of the world. We study the order of things, says Browne, but we cannot grasp their innermost essence. And because it is so, it befits our philosophy to be writ small, using the shorthand and contracted forms of transient Nature, which alone are a reflection of eternity.
page 15: caecilians. This one, the Atretochoana, looks like a penis snake:



page 15: The greatest amphibian extinction since the Permian. Actually, it looks as if it's bigger:
Species are estimated to be going extinct 40,000 times faster than at any time since the first amphibians crawled out of the water 360 million years ago. No one knows what the long-term consequences will be... The killer, in many cases, is a single-celled fungus called Batrachochytrium dendrobatidis (Bd)..."We're seeing a breakdown in global biosecurity that's having a profound impact on natural environments. We're seeing it in plant systems, we're seeing it in animal systems, and we're seeing it in human systems as well. It's pretty terrifying."

In praise of error...and elephants

Fourth in a series of notes and comments on The Book of Barely Imagined Beings


Chapter 1: Axolotl

page 2: The first epigraph is from Jubilate Agno by Christopher Smart, written between 1759 and 1763 during his confinement for insanity in St. Luke's Hospital in London.

page 2: The second epigraph is from a report by Benjamin Franklin and others into an investigation of animal magnetism undertaken for the King of France in 1784.  David Deutsch recently argued that error remains a vital to knowledge:
genuine knowledge, though by definition it does contain truth, almost always contains error as well. Thinking consists of criticising and correcting partially true guesses with the intention of locating and eliminating the errors and misconceptions in them, not generating or justifying extrapolations from sense data. 
A pleasing example of a correct conclusion derived from incomplete evidence is the proof by elephants attributed to Aristotle:
When one travels west from Greece, one finds [African] elephants . When one travels east one finds [Asian] elephants.  Therefore the Earth is round.
