Book review – Ancestors in Our Genome: The New Science of Human Evolution

After I read and reviewed Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past, I thought I knew about the changes to the story of human evolution based on studies of DNA. And given that Ancestors in Our Genome was published a few years before that book, I was curious what it could add to what I had been reading so far. As it turns out, a lot. As with my previous review, I should preface this one with the same warning that things are about to get complicated…

Book review – End of the Megafauna: The Fate of the World’s Hugest, Fiercest, and Strangest Animals

Mammoths and sabertooth cats are but two icons of an assemblage of large animals, or megafauna, that disappeared between roughly 50,000 to 12,000 years ago. As with all mass extinctions, several explanations have been put forward, but one man and his idea take centre stage in these discussions: Paul S. Martin’s overkill hypothesis. In End of the Megafauna, palaeomammalogist Ross D.E. MacPhee carefully scrutinises this idea, weighs up the arguments for and against, and explains its enduring allure. To quote Huxley, is this another example of “the slaying of a beautiful hypothesis by an ugly fact”?

Book review – When Humans Nearly Vanished: The Catastrophic Explosion of the Toba Volcano

When it comes to big volcanic eruptions, names such as Vesuvius, Mount Saint Helens, and Krakatau will ring a bell. But all of these are dwarfed by a far larger eruption that few outside of the science community will have heard of. Noted geologist, palaeontologist and author Donald R. Prothero here tells the story of the eruption of Mount Toba in what is nowadays Sumatra, Indonesia, some 74,000 years ago. An eruption so gargantuan that it almost wiped out the human race.

Book review – The Book of Humans: The Story of How We Became Us

Historically, humans have long considered themselves special compared to the natural world around them. It shows, for example, in old depictions where humans are at or near the top of a chain of lifeforms, with only angels and gods above us. Darwin caused a tremendous ruckus by saying we were descended from primates, and evolutionary biology has since had a long history of diminishing our anthropocentric worldview. With The Book of Humans, self-professed science geek Adam Rutherford has written an entertaining exploration of human evolution, showing that, amidst the teeming multitudes of lifeforms surrounding us, we are really not that special. And yet we are.

Book review – She Has Her Mother’s Laugh: The Powers, Perversions, and Potential of Heredity

If Charles Darwin were to walk into my office today and ask me: “So, what did I miss?” I think I would sit the good man down with a copy of She Has Her Mother’s Laugh, telling him: “Here, this should get you up to speed”. Darwin struggled to explain how traits were being inherited from generation to generation. As New York Times columnist Carl Zimmer shows in this wide-ranging book, the story of heredity has turned out to be both diverse and wonderful, but has also been misappropriated to prop up some horrible ideologies.

Book review – Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past

You may have missed it, but archaeology is undergoing a silent revolution. The story of our deep history used to be based on skeletal remains, linguistics, and the analysis of objects and tools our ancestors left behind, but since about three years archaeologists have a new tool in their arsenal. The analysis of DNA from old bones, or ancient DNA. David Reich has been at the forefront of developing this technique and argues that it is rewriting most of what we thought we knew about the last 350,000 years or so of human history. Brace yourself, things are about to get complicated…
