Review – The Edge of Memory

Posted April 6, 2019 by Nicky in Reviews / 0 Comments

Cover of The Edge of Memory by Patrick NunnThe Edge of Memory, Patrick Nunn

Patrick Nunn’s premise is that oral traditions may preserve details about events from a long time ago — not just decades, but centuries, and even millennia. He goes about trying to prove this by taking inundation stories as an example, linking them to post-glacial sea rise events, and trying to prove that the stories accurately depict the experiences of the tellers’ ancestors. I think his basic point is proven anyway: we know that oral traditions can preserve an amazing amount of detail over astonishing lengths of time. Homer’s Iliad and Odyssey were written down long after the events they describe, with clear features showing they were actually performed aloud and passed from person to person in a feat of memory. We know that this survival wasn’t just a matter of a generation or two, because the stories contain clear details that were no longer relevant to the time when the stories were actually written down: weaponry, customs and geopolitics were different, but are preserved in the epics with a surprising degree of fidelity.

However, I think Nunn tries to go too far, and is generally pretty unsound. For one example that made me question his research, he mentions his theory that people originally created rock art as a sort of aide-memoire, on the grounds that they wouldn’t have done anything that didn’t aid in survival — that it must be so, because they wouldn’t have had time for anything other than survival. However, the 40 hour work week is actually a purely post-Industrial construct: modern hunter-gatherers — even living in a world circumscribed by land ownership and industry, i.e. with nowhere near the range they would have had prehistorically — need to spend far less time on subsistence. Anything from 2 hours a day to 8 hours is suggested, most of it on the lower end of that scale; if nothing else, hunter-gatherers had the same amount of free time as modern humans, likely more.

That’s a comparatively minor point, but it definitely made me sceptical. Add to that Nunn’s tendency to use phrases like “it is plausible to assume” and “it seems likely”, and his rather circular attempts to use sea levels to date the stories and stories to date the sea levels, and I’m extra-sceptical. These are mythic stories — things like a kangaroo digging a hole that causes the sea to flood in — and his interpretations are faltering. Does it mean X? Does it mean Y? At one point he says the presence of a particular feature in a story proved it referred to a permanent inundation and then later, though I suspect this was bad editing, seems to say the opposite of another story (it didn’t contain the same feature, and therefore still referred to a permanent inundation — what?!).

I think Nunn attempts to use two things that are necessarily imprecise to date each other, and gets tangled up in the relationship between those. I’d much rather see some underwater archaeology to show that people were living in these locations at the right time, as a kind of independent third corroboration. I think he’s particularly shaky when he discusses stories where drowned buildings are clearly visible beneath the water: it’s obvious that those stories cannot be purely handed down from the time of the inundation, but will have been reinforced, changed, or possibly even invented by new tellers, when the drowned buildings were observed in later times.

The basic premise that oral culture can preserve some astonishing detail from very far in the past is undeniable, and I commend Nunn’s use and examination of Australian Aboriginal stories in particular — I think it was a sound choice given their isolation from other people’s and the strength of their oral culture. I just think Nunn tries to stand up a stool with only two legs (the stories and sea levels), and should definitely have thought about other ways to establish his theories.

Obviously this is not my field in any sense, though I have a background in scientific investigation, so take my opinion for what you think that’s worth. I found the book interesting and largely well-written, even if the arguments are weak. I did find the recounting of every single individual inundation story known to the author rather tedious. There’s something like 21 one of them: pick the best ones, dude. Make a table to compare them. Just… something!

Review – Lucy: The Beginnings of Humankind

Posted April 4, 2019 by Nicky in Reviews / 0 Comments

Cover of Lucy: The Beginnings of MankindLucy: The Beginnings of Humankind, Donald Johanson, Maitland Edey

This book might be a little old by now, and somewhat superceded by discoveries of other Austrolopithecines and Homo naledi, but it’s excellent for getting a solid understanding of the issues surrounding how we understand human evolution. It’s also excellent as a way of understanding the kind of environment that kind of research and debate is going on within — things have changed now in several ways, no doubt, but the methods of study and research are still true, and an understanding of the existing fossils –and how they were categorised — from when Johanson wrote is still useful.

I have to admit, I wondered about the obvious sour grapes between Johanson and the Leakeys that came up several times in this book. They were such renowned scientists — and honestly, I’d still remember their names before Johanson’s, despite the fame of ‘Lucy’ — but they were so wrong and so unscientific, in this view. It makes me wonder. Obviously, personal bias is likely to have coloured things here!

My favourite part was probably the final section, in which Johanson discussed theories about why humans are bipedal. It’s clearly argued, and while I agree with the critique mentioned in the book itself (I love the line “I’ve never seen an estrus fossil” as a retort), it mostly hangs pretty well together. (Basically: humans are bipedal to effectively look after children, increasing the number of offspring one woman can have; an advantage over most apes, who keep to one child at a time.)

Good stuff, still.

Review – T. Rex and the Crater of Doom

Posted March 28, 2019 by Nicky in Reviews / 0 Comments

Cover of T. Rex and the Crater of Doom by Walter AlvarezT. Rex and the Crater of Doom, Walter Alvarez

In this book, Walter Alvarez discusses the problem, process and solution in figuring out how the KT boundary extinction happened (yep, that’s the death of the dinosaurs). Despite the rather sensational sounding title, it’s a thoughtful book: aimed at the layperson, undoubtedly, but still discussing the process of obtaining evidence, and what that evidence means, in some detail. I found his writing incredibly clear, and though I’m not exactly the right person to judge, I think any intelligent and interested person should be able to follow his arguments.

It’s also oddly charming that instead of talking about Luis Alvarez (Nobel prizewinning scientist) by name, or even as “my father”, he’s called “Dad” throughout. “Dad thought up this idea… I spoke to Dad…” etc.

Obviously, Alvarez doesn’t present many downsides to his own theory, and I imagine there have been more refinements and adjustments since this was published in 1997, but it’s still a surprisingly compulsive read. The opening is surprisingly literary, revealing a love of Tolkien.

My kinda guy, clearly.

Review – A Brief History of Everyone Who Ever Lived

Posted March 13, 2019 by Nicky in Reviews / 2 Comments

Cover of A Brief History of Everyone Who Ever Lived by Adam RutherfordA Brief History of Everyone Who Ever Lived, Adam Rutherford

It’s an ambitious title, and it should come as no surprise that that’s not really a history of everyone who ever lived. It’s really a story about some of the things we know from our genes, and it’s a bit of a random sampling at that, covering ear wax (those who have studied genetics will find this no-shocker, since wet vs sticky earwax is a fairly common example of a certain kind of genetic trait), kings, disease, migration, redheads, and all kinds of things in between. To me, it read like a grab bag of interesting facts we know about genetics: yes, the facts are interesting, but a coherent argument leading through a book it is not.

Rutherford’s not a bad writer, and he clearly has an eye for a good story, but… first of all, this level of pop-science is a bit too pop for me now, and secondly, it’s a disorganised mess.

Review – The Copernicus Complex

Posted March 10, 2019 by Nicky in Reviews / 0 Comments

Cover of The Copernicus Complex Caleb ScharfThe Copernicus Complex, Caleb Scharf

Ostensibly, this book is about a simple question: are humans alone in the universe? It has to go the long way around to come to any answers, exploring other arguments by way of figuring out whether the Earth is or isn’t rare in the universe and whether or not life is as tightly constrained as some people say, but the core principle of the book is that we need to find a middle ground between the current main ideas — the Copernican view that we can’t be unique, and the Rare Earth view that says life in the universe must be unusual.

Mostly, my wife got to watch me mutter “yes, obviously”, and I’m tempted to quote Lord Peter on Chief Inspector Parker here — it takes Scharf a desperately long time to someone who already has a somewhat formed opinion to “crawl distantly within sight of a conclusion”. That conclusion, in the end, is basically where I stand: not enough data, come back later (with a side of Scharf being pretty sure that neither extreme is going to turn out to be correct, with which I disagree — I think it’s all up for grabs at this point).

So anyway, if you want to know why I came to the conclusion I’ve written in my science blog recently (i.e. “we don’t know and we can’t know based on the current data we have”), this book has a good roundup of the evidence. Scharf isn’t bad at explaining it.

But if you’re looking for answers, I find it as unconvincing as all the other attempts at answering this question.

Review – Pale Rider

Posted March 6, 2019 by Nicky in Reviews / 0 Comments

Cover of Pale Rider by Laura SpinneyPale Rider, Laura Spinney

Pale Rider is about the 1918 flu pandemic known as “Spanish flu”: the fact that it killed many more people than the Great War did is a well-known fact now, and this particular pandemic is credited with making scientists realise the dangers of a global health crisis like this — and the likelihood that it could and would happen again.

I’ll confess, I didn’t think I’d learn that much about the flu from reading this book, having already read John M. Barry’s The Great Influenzabut in fact there was a lot here that was new to me. Not so much in understanding the disease itself — if Barry’s book didn’t do that, studying for my exams certainly did — but in understanding the impact it had on the world, and particularly on non-Western countries. There’s a lot here that’s new to me about China and Russia, for instance, whereas I feel like The Great Influenza focused much more on the American side of things.

There’s also, I feel, more of an attempt to understand the social and political effects of the pandemic, rather than just the medical and scientific.

However, my end feeling is the same: influenza is a fascinating topic, and if it doesn’t scare you (in a measured informed way that leads to taking sensible precautions like getting the flu vaccine every year), it should. Spinney has a common-sense approach to it all — there’s a lot of things that need to align to make a pandemic, and Spinney doesn’t overstate the likelihood of that happening, but she does lay out the risks and emphasise the need for data collection and disease surveillance. Hear hear!

Review – Molecules at an Exhibition

Posted February 8, 2019 by Nicky in Reviews / 0 Comments

Cover of Molecules at an Exhibition by John EmsleyMolecules at an Exhibition, John Emsley

This started out fascinating, but started to wear on me. Basically, it’s a ‘gallery’ of various molecules that are important in one way or another to human life. There are nutrients we require, poisons that kill us, fuels we use, things that make useful objects, etc, etc. It’s possibly better just being dipped into than read cover to cover; I certainly got tired of all the fuels and the relatively similar titbits about some of the elements. It’s not bad, but it didn’t keep me very interested either.

I’m hoping his book specifically on poisons is more up my street…

DNF Review – A Little History of Science

Posted January 21, 2019 by Nicky in Reviews / 3 Comments

Cover of A Little History of Science by William F BynumA Little History of Science, W.F. Bynum

If you don’t actually know much about the history of science, this book might well be for you; for me, it was painfully obvious, hitting exactly the topics I expected, skimming over what I expected it to skim. A worse crime, however, is that the author simply wasn’t accurate: if you’re going to write a non-fiction book, it’s important to make sure you don’t speak beyond your research.

It does not take much research to find out that Egyptian hieroglyphs and Chinese characters are not pictographic representations of language. (To be perfectly accurate, some of the characters echo in form the thing they name; a cow head shape might mean the word cow, for instance. However, the languages also contain phonetic characters.)

I didn’t read beyond that. On that point, I knew the author was wrong — on a subject that isn’t even a particular area of expertise for me; how, therefore, could I trust him to have done his research about anything else? If we’re talking deeply technical details, that’s different, but it is widely understood that Egyptian hieroglyphs and Chinese characters are not solely logographic. There’s too little time for something where I distrust the research and editing and I’m bored.

Review – The Crucible of Creation

Posted January 17, 2019 by Nicky in Reviews / 0 Comments

Cover of The Crucible of Creation by Simon Conway MorrisThe Crucible of Creation, Simon Conway Morris

Part discussion of the Burgess Shale, part rebuttal of Stephen Jay Gould’s premises in Wonderful Life, this book was a bit of a slog to get through for me. It’s a topic I find fascinating, but something about the style mostly had me snoozing, even when he entertainingly decided to take a turn for the science fictional and imagine a whole dive into the seas at the time of the Cambrian explosion. (That bit was mostly entertaining through being surprising, though also through trying to bring to life the animals that could’ve been seen if that could happen, and how they would have behaved — the most speculative bit of the book, basically.)

I feel like Wonderful Life is probably the more fun to read and the more comprehensive, but it’s still fascinating to read about the point of view of a scientist who has actually worked with the Burgess Shale. Whatever you think of Conway Morris’ style, he’s a scientist Gould respected and an expert in his field.

Review – Endless Forms Most Beautiful

Posted October 15, 2018 by Nicky in Reviews / 0 Comments

Cover of Endless Forms Most Beautiful by Sean CarrollEndless Forms Most Beautiful, Sean Carroll

At this point, I must admit I’m a bad judge of pop-science when it covers biology. To me this is a very easy read now, covering simple topics, but I know I wouldn’t have felt that way a couple of years ago. If you’re interested in evolutionary biology, though, this is a very good primer on the science of Evo Devo: understanding evolutionary relationships through understanding the development of embryos, how certain genes work in causing large morphological differences even though almost the same gene can be found in a wildly different species.

think if you have a reasonable understanding of genetics and how proteins are made, you should be okay here: it’s not requiring expertise, though it may take concentration to follow some of the reasoning if you’re not already familiar. If you are, it illustrates the principles nicely, and I imagine a full colour copy of the book (if it exists) would be rather physically gorgeous as well. There’s a lot of black-and-white images of butterfly wings, for instance, in my particular edition. The points could probably have been more clearly demonstrated with colour images where the differences are easier to highlight…

All the same, a fascinating book, whether you’re an expert or not (I think). Evo Devo is a bit of a buzzword for some biologists lately, and this book is worth the read for learning about that. I wish I’d read it before the module I did that included some of this stuff: it would have definitely made the learning part come easier!
