Book review – Terrestrial Impact Structures: The TanDEM-X Atlas (2-Volume Set)

7-minute read

When Google Earth first launched in 2001, I, like many others, found myself poring over satellite imagery. Identifying familiar and unfamiliar landmarks always brought a certain thrill, and spotting craters was part of that. But to properly map impact structures, you need a better dataset. The stunningly produced Terrestrial Impact Structures is a large-format atlas that maps all currently accepted ones, plus some likely candidates, and makes for an instant must-have reference work for any geology or astronomy library.

Book review – Contingency and Convergence: Toward a Cosmic Biology of Body and Mind

6-minute read

This is the final of three reviews of MIT Press books in The Vienna Series in Theoretical Biology dealing with convergent evolution, something I consider to be one of evolutionary biology’s most exciting topics. Are evolutionary changes happy accidents, i.e. contingencies? Or is there a law-like repeatability underneath, explaining why some traits evolve time and again, i.e. convergence? Is it even a matter of either-or? And what lessons does this hold for life elsewhere in the universe? Philosopher Russell Powell wrestles with these questions in a manner that is as rigorous as it is intellectually rewarding. Evolutionary biologists will want to give this excellent book a very close read.

Book review – Convergent Evolution on Earth: Lessons for the Search for Extraterrestrial Life

6-minute read

Planet Earth might just as well be called Planet Water. Not only is our planet mostly ocean, life also started out here. Following his 2011 book Convergent Evolution, palaeobiologist George R. McGhee returns to MIT Press and The Vienna Series in Theoretical Biology to expand his examination to oceanic lifeforms, with the tantalising promise of applying the insights gained to astrobiology. I was particularly stoked for this second of a three-part dive into what I consider one of evolutionary biology’s most exciting topics.

Book review – Convergent Evolution: Limited Forms Most Beautiful

6-minute read

Convergent evolution was the subject of the first book I reviewed on this blog and is a topic I keep returning to. MIT Press recently published two further books on it, Convergent Evolution on Earth in 2019 and Contingency and Convergence in 2020. I felt the time was ripe to finally read their 2011 book Convergent Evolution that I bought some years ago. All three of these are part of The Vienna Series in Theoretical Biology, a series I hold in high regard. This, then, is the first of a three-part dive into what I consider one of evolutionary biology’s most exciting topics.

Book review – Finding our Place in the Universe: How We Discovered Laniakea – the Milky Way’s Home

6-minute read

The images that astronomers produce can shape whole generations. Based on the Pale Blue Dot photo taken by the Voyager 1 space probe, Carl Sagan’s moving speech in Cosmos highlighted how small and insignificant we appear in the vastness of the universe. But we are not alone, being part of the solar system which is part of the Milky way galaxy. And ours is but one of billions, possibly trillions, of galaxies in the universe that, interestingly, are not scattered at random in space. In this compact and engagingly written book, French cosmographer Hélène Courtois shows you the next level up: superclusters. When it was published in 2014, the image of the supercluster to which our galaxy belongs for me was another one of those generation-defining images. It was of such stunning beauty that it stopped me in my tracks. Welcome to Laniakea, our home amidst the stars.
