Human Origins, a short history - Sarah Wild ***

It's inevitable that us humans have a distinct interest in where we come from as a species, and in this book Sarah Wild takes us through the latest state of knowledge on the origin of our species and of the various extinct species that broadly fall within the 'hominin' descriptor.

There's plenty of compact information here, with occasional boxes filling in basics, such as how fossils form and what a hominin is. Some of the facts are eminently quotable - my favourite was that of all the species mentioned, only Homo sapiens has a chin (not sure what this says about chinless wonders). I particularly liked the chapters on 'the first sapiens' - what we know about the earliest members of our species - and on 'the big questions', notably what happened to all the other related-ish species and the ways in which we are still evolving.

Unfortunately, though, the book does suffer from Rutherford stamp collecting syndrome. The great physicist commented (roughly) that all science is either physics or stamp collecting - suggesting that other scientific disciplines focus too much on collecting and collating data, where physics is more about deducing laws and explanation of phenomena (hence far more interesting). Wild gives us a plethora of data and species, with many different hominins named, and their distinguishing features reeled off. What's missing is a sense of storytelling and narrative - it's just too fact-heavy.

Just to give one example: in a section labelled 'Homo mysteries', Wild introduced the famous 'hobbit' of the Indonesian island of Flores. We hear about where the remains were found, the excavations, the species' strange mix of characteristics and the debate over whether the remains were of a new species or of individuals with birth defects. But nowhere is there a mention of the best bit of the story (appearing in Henry Gee's The Accidental Species), that the discoverers originally suggested naming the species Homo florianus, but hastily renamed it Homo floresiensis when they discovered their original name means a flowery part of the anatomy. It might be trivial, but a story like this adds human interest. Similarly we hear very little other about the discoverers than their names - ironically, it would have been great to give more human context.

I was also uncomfortable with Wild's use of the word 'ancestor'. As far as I'm concerned, an ancestor is in a species' direct lineage. But at one point we are told 'For many years [Ardipithecus ramidus] was the oldest human ancestor we knew of.' Yet, as we are correctly told some pages later, 'We do not know how the human lineage evolved from early hominins' - all we have is fragments of different earlier hominins, many of which will not be our ancestors, and we have no way of being clear when dealing with specimens too old for genetic identifiers.

The book was absolutely fine as a textbook light, and I was happy to endorse it as such. If you need to get information about the context of human evolution, it will give a good collection of facts (if we overlook the ancestor thing) - but it hasn't got the readability of good popular science.

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader.  We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard.  This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

The Infinity Machine - Sebastian Mallaby ****

It's very quickly clear that Sebastian Mallaby is a huge Demis Hassabis fan - writing about the only child prodigy and teen genius ever who was also a nice, rounded personality. After a few chapters, though, things settle down (I'm reminded of Douglas Adams' description of the Hitchhiker's Guide to the Galaxy ) and we get a good, solid trip through the journey that gave us DeepMind, their AlphaGo and AlphaFold programs, the sudden explosion of competition on the AI front and thoughts on artificial general intelligence. Although Mallaby does occasionally still go into fan mode - reading this you would think that AlphaFold had successfully perfectly predicted the structure of every protein, where it is usually not sufficiently accurate for its results to have direct practical application - we get a real feel for the way this relatively unusual company was swiftly and successfully developed away from Silicon Valley. It's readable and gives an important understanding of...

Nanotechnology - Rahul Rao ****

There was a time when nanotechnology was both going to transform the world and wipe us out - a similar position to our view of AI today. On the positive transformation side there was K. Eric Drexler's visions in the 1986 Engines of Creation. Arguably as much science fiction as engineering possibilities, it predicted the ability to use vast armies of assemblers to put objects together from individual atoms.  On the negative side was the vision of grey goo, out of control nanotechnology consuming all in its path as it made more and more copies of itself. In 2003, for instance, the then Prince Charles made the headlines  when newspapers reported ‘The prince has raised the spectre of the “grey goo” catastrophe in which sub-microscopic machines designed to share intelligence and replicate themselves take over and devour the planet.’ These days the expectations have been eased down a notch or two. Where nanotechnology has succeeded, it has been with the likes of atom-thick mat...
