As one of several intellectuals who wrote about evolution before Darwin, time has not been kind to the French naturalist Jean-Baptiste Lamarck (1744-1829). Reviled during his lifetime by the influential Cuvier, after his death he became best remembered, and ultimately ridiculed, for the idea that characters acquired during an organism’s lifetime are passed on to its offspring. With the rise of the modern field of epigenetics, some of his ideas are making a comeback, albeit modified and adapted for the 21st Century. Palaeontologist and astrobiologist Peter Ward would even like to go so far as to restore some honour to his name and consider epigenetics a neo-Lamarckian process.
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…
Animal anatomy has fascinated artists and scientists for millennia, resulting in a treasure trove of striking images. Veterinary anatomist David Bainbridge here takes on the brave task of curating a bird’s-eye-view of anatomical artwork that simultaneously delights, educates, and (for some perhaps) horrifies.
When you think of an animal, you will most likely think of a vertebrate. Since we are animals with a backbone ourselves, it is not strange that that which is closest to us comes to mind first. But when and how did vertebrates evolve? To answer that question, Nature editor Henry Gee takes a good hard look at invertebrates, convincing the reader that they are not all equal. More than 20 years ago, Gee wrote Before the Backbone: Views on the Origin of the Vertebrates, which took a look at historical explanations for the origins of vertebrates. Which group of invertebrates is closest to us remains a topic of active research and Across the Bridge brings readers up to date with our current thinking.
When I think of turn-of-the-20th-century palaeontology, names such as Othniel Charles Marsh and Edward Drinker Cope are the first to come to mind. Their infamous rivalry, known as the Bone Wars, relied heavily on field collectors who did the back-breaking labour of prospecting and quarrying for fossils. Most of these bone hunters are barely remembered, and John Bell Hatcher might very well have remained thus. This meticulous biography by American palaeontologist Lowell Dingus saves Hatcher from obscurity and documents both his hugely successful work as a bone hunter, as well as his later stellar but tragically short-lived career as a curator.
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.
When it comes to Ice Age fame, sabertooth cats are right up there with mammoths. And within the sabertooth cats, the best-known group is the genus Smilodon. Even if you have not heard that name, you will very likely have seen it depicted. Rather than a pop-science book, this edited collection brings together the who-is-who of sabertooth palaeontology to provide a thorough and technical overview of the current state of the field. And if I did not know any better, I would say that the research community has developed an almost unhealthy obsession with this cat’s large canine teeth.
At first blush, you might think this book is part of the ongoing craze of spiritual mindfulness books. But let me refrain from snarky comments. Geologist Marcia Bjornerud does indeed want to instill a sense of mindfulness about deep time, but one that is, pardon the pun, grounded in geology. In her opinion, most of us lack an awareness of durations of important chapters in our planet’s history and of rates of change of many natural processes. As a consequence, we fail to see just how rapidly we are altering our planet. In one of the first paragraphs she eloquently writes:
“Like inexperienced but overconfident drivers, we accelerate into landscapes and ecosystems with no sense of their long-established traffic patterns, and then react with surprise and indignation when we face the penalties for ignoring natural laws”.
And with that, she had me hooked.
Given that dinosaurs are no longer around, everything you think you know about what they look like comes from illustrations, models, movies, and merchandise. But how much of this is actually accurate, and how much of it is rather geared towards appealing to our sensibilities? Mark Witton is a man with a mission: to elevate the genre of palaeoartistry to one depicting scientifically accurate renditions, based on informed speculation and careful study of fossils and anatomy. Rather than a book that shows you how to draw a dinosaur, The Palaeoartist’s Handbook is a fantastically useful primer for both aficionados and budding artists into what actually can and should go into making good palaeoart.
Where do fossils belong? Should they be housed in museums, available for study by scientists to learn more about our planet’s deep history? Or can they be treated like exclusive souvenirs, traded and auctioned on a market that stocks the private collections of rich people? Journalist Paige Williams here tells the full story, warts and all, of a high-profile auction gone awry. She initially reported on this in 2013 in the New Yorker. Up for sale? A fully reconstructed skeleton of Tarbosaurus bataar, the Asian cousin of Tyrannosaurus rex.
