The Southern Ocean, that vast body of water that flows unhindered around Antarctica, has to be one of the most forbidding oceans on our planet. Its latitudes are referred to by increasingly unnerving names the gale-force winds that have terrorised mariners since they first set sail here – the roaring forties, the furious fifties, the screaming sixties. Its waters are so cold that they are actually below freezing in places, with only their salinity preventing them from freezing solid (fish here have evolved antifreeze proteins!) As a consequence of these extreme conditions, this region has long remained unexplored. But, as historian Joy McCann shows, explore it we did. Brace yourself for a gripping piece of environmental history, marked by heroism as much as hubris, and curiosity as much as cruelty.
Origins asks one question: how did the Earth make us? More accurately, like a six-year-old whose curiosity cannot be sated, there lies a series of recursive “why” questions at the heart of this book. Astrobiologist and science communicator Lewis Dartnell takes a big history look at human evolution and especially civilization, seeing how far down the explanatory rabbit hole he can go. Time and again, he grounds his answers in geology and geography. You would be forgiven for thinking this sounds like what Jared Diamond attempted more than two decades ago, but calling it Diamond-redux would not do it justice.
When I reviewed the book Defending Biodiversity: Environmental Science and Ethics, one of the reasons that was discussed as to why we should protect nature was the possibility of undiscovered pharmaceutical drugs. Seasoned ethnobotanist Robert A. Voeks shows that this so-called jungle medicine narrative has a long history. Though partially true, it equally contains parts myth, sentimentality, and nostalgia. However, if you are expecting a sceptical critique of superstitious indigenous practices – I was initially wondering whether the book would – no, this book delivers something far more interesting. Without belittling traditional knowledge, Voeks instead exposes the flaws in our interpretation and delivers a nuanced and fascinating ethnobotanical history lesson to boot.
They say you should not judge a book by its cover, but in this case, it was the very attractive cover that drew me to read Erebus: The Story of a Ship. Michael Palin, known equally for his early work as part of the Monty Python troupe as for his travel documentaries, here tells a riveting story from the golden age of polar exploration. A tale of high-spirited British imperialism, marine camaraderie, a warship that wasn’t, and the enduring mystery of a vanished Arctic expedition.
Before plate tectonics became an accepted idea in geology, Lyell’s doctrine of uniformitarianism still ruled supreme (see my review of Cataclysms: A New Geology for the Twenty-First Century for a short introduction). A corollary was that the continents supposedly had always been where they are now. One observation scholars had to explain away was that the same fossils occur on both sides of the various oceans. Looking at maps, some people noticed the thin strip of land connecting North and South America and concluded that land bridges must have formed and sunk beneath the waves at just the right times in history to enable migrations (see Four Revolutions in the Earth Sciences: From Heresy to Truth for more details). As explained in The Tectonic Plates are Moving!, we know better nowadays. Nevertheless, the concept of land bridges is still alive and well today, and palaeobotanist Alan Graham here introduces five of them, exploring their effects on biogeography, climate, and human history.
