A robust defense of Charles Darwin’s aesthetic theory of evolution.

Prum (Ornithology/Yale Univ.), the head curator of vertebrate zoology at the Yale Peabody Museum of Natural History, argues that natural selection is not the only evolutionary mechanism at work in nature. Beauty and desire in nature are also dynamic forces, and those features in males that females prefer in choosing mates evolve rapidly. In a nutshell, each species evolves its own standard of beauty by which it chooses mates. After a brief discussion of the early and continued opposition to Darwin’s aesthetic theory, the author illustrates the role of beauty in bird mating by taking readers to Borneo to observe the rituals of the Great Argus, a species of pheasant known as “one of the most aesthetically extreme animals on the planet,” and to Suriname, to see the displays of male manakins, which must meet the “very high standards” of potential female mates. In other chapters, Prum reveals the intricate machinery involved in female bowerbirds choosing their mates. Female ducks, it seems, may not have such autonomy. Readers may be in for a shock when Prum turns to duck sex, which can be violent, involving what humans would call gang rape, and the illustrations of record-setting duck penises are eye-opening. The author, who charmingly reveals his lifelong fascination with birds, does not base his argument solely on avian evolution, however. In later chapters, he explores the role of female mate choice in primate evolution, a challenging subject that he views as warranting further study. Throughout, the narrative is well-documented and wholly accessible, enriched by the author’s warm personal touches.

Prum writes that his goal was to present the “full, distinctive richness, complexity, and diversity of this aesthetic view of life.” He absolutely succeeds, though fierce debate will continue among evolutionary biologists.

A collection of articulate, forceful speeches made from September 2018 to September 2019 by the Swedish climate activist who was nominated for a Nobel Peace Prize.

Speaking in such venues as the European and British Parliaments, the French National Assembly, the Austrian World Summit, and the U.N. General Assembly, Thunberg has always been refreshingly—and necessarily—blunt in her demands for action from world leaders who refuse to address climate change. With clarity and unbridled passion, she presents her message that climate change is an emergency that must be addressed immediately, and she fills her speeches with punchy sound bites delivered in her characteristic pull-no-punches style: “I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act.” In speech after speech, to persuade her listeners, she cites uncomfortable, even alarming statistics about global temperature rise and carbon dioxide emissions. Although this inevitably makes the text rather repetitive, the repetition itself has an impact, driving home her point so that no one can fail to understand its importance. Thunberg varies her style for different audiences. Sometimes it is the rousing “our house is on fire” approach; other times she speaks more quietly about herself and her hopes and her dreams. When addressing the U.S. Congress, she knowingly calls to mind the words and deeds of Martin Luther King Jr. and John F. Kennedy. The last speech in the book ends on a note that is both challenging and upbeat: “We are the change and change is coming.” The edition published in Britain earlier this year contained 11 speeches; this updated edition has 16, all worth reading.

A tiny book, not much bigger than a pamphlet, with huge potential impact.

As much a work of philosophy as of physics and full of insights for readers willing to work hard.


Undeterred by a subject difficult to pin down, Italian theoretical physicist Rovelli (Reality Is Not What It Seems: The Journey to Quantum Gravity, 2017, etc.) explains his thoughts on time.

Other scientists have written primers on the concept of time for a general audience, but Rovelli, who also wrote the bestseller Seven Brief Lessons on Physics, adds his personal musings, which are astute and rewarding but do not make for an easy read. “We conventionally think of time,” he writes, “as something simple and fundamental that flows uniformly, independently from everything else, uniformly from the past to the future, measured by clocks and watches. In the course of time, the events of the universe succeed each other in an orderly way: pasts, presents, futures. The past is fixed, the future open….And yet all of this has turned out to be false.” Rovelli returns again and again to the ideas of three legendary men. Aristotle wrote that things change continually. What we call “time” is the measurement of that change. If nothing changed, time would not exist. Newton disagreed. While admitting the existence of a time that measures events, he insisted that there is an absolute “true time” that passes relentlessly. If the universe froze, time would roll on. To laymen, this may seem like common sense, but most philosophers are not convinced. Einstein asserted that both are right. Aristotle correctly explained that time flows in relation to something else. Educated laymen know that clocks register different times when they move or experience gravity. Newton’s absolute exists, but as a special case in Einstein’s curved space-time. According to Rovelli, our notion of time dissolves as our knowledge grows; complex features swell and then retreat and perhaps vanish entirely. Furthermore, equations describing many fundamental physical phenomena don’t require time.

As much a work of philosophy as of physics and full of insights for readers willing to work hard.
