Europe’s first farmers

EIGHT thousand years ago small bands of seminomadic hunter-gatherers were the only human beings roaming Europe’s lush, green forests. Archaeological digs in caves and elsewhere have turned up evidence of their Mesolithic technology: flint-tipped tools with which they fished, hunted deer and aurochs (a now extinct species of ox), and gathered wild plants. Many had dark hair and blue eyes, recent genetic studies suggest, and the few skeletons unearthed so far indicate that they were quite tall and muscular. Their languages remain mysterious to this day…

Food, globalisation and pandemics

ONCE a dangerous new pathogen is out, as we are seeing, it can be difficult if not impossible to prevent it going global. One as contagious as SARS-CoV-2 has the potential to infect the whole of humanity. Eighty per cent of cases may be benign, but with such a large pool of susceptible hosts, the numbers who experience severe illness and die can still be shockingly high. So the only sensible answer to the question, how do we stop this from happening again, is: by doing all we can to prevent such pathogens infecting humans in the first place.

Things will surely shift again, as people realise that the self-confinement could last and escapism becomes our collective goal, but for now Adam Kucharski’s The Rules of Contagion is the book you might want to reach for.

The end is nigh

IN case you missed it, the end is nigh. Ever since Jared Diamond published his hugely popular 2005 work Collapse, books on the same theme have been arriving with the frequency of palace coups in the late Roman Empire. Clearly, their authors are responding to a universal preoccupation with climate change, as well as to growing financial and political instability and a sense that civilization is lurching towards a cliff edge. Mention is also made of how big-data tools are shedding new light on historical questions. But do these books have anything useful to share? Any actionable points besides that on my coffee mug: “Now panic and freak out”? …
