What We Are Reading Today: Homology, Genes, and Evolutionary Innovation, by Günter P. Wagner

Homology — a similar trait shared by different species and derived from common ancestry, such as a seal’s fin and a bird’s wing — is one of the most fundamental yet challenging concepts in evolutionary biology. This groundbreaking book provides the first mechanistically based theory of what homology is and how it arises in evolution, says a review on the Princeton University Press website.

Günter Wagner, one of the preeminent researchers in the field, argues that homology, or character identity, can be explained through the historical continuity of character identity networks — that is, the gene regulatory networks that enable differential gene expression. 

He shows how character identity is independent of the form and function of the character itself because the same network can activate different effector genes and thus control the development of different shapes, sizes, and qualities of the character. 

Demonstrating how this theoretical model can provide a foundation for understanding the evolutionary origin of novel characters, Wagner applies it to the origin and evolution of specific systems, such as cell types; skin, hair, and feathers; limbs and digits; and flowers.

What We Are Reading Today: The Conqueror’s Gift by Michael Maas

Ethnography is indispensable for every empire, as important as armies, tax-collectors, or ambassadors. It helps rulers articulate cultural differences, and it lets the inhabitants of the empire, especially those who guide its course, understand themselves in the midst of enemies, allies, and friends.

In “The Conqueror’s Gift,” Michael Maas examines the ethnographic infrastructure of the Roman Empire and the transformation of Rome’s ethnographic vision during Late Antiquity. 

Drawing on a wide range of texts, Maas shows how the Romans’ ethnographic thought evolved as they attended to the business of ruling an empire on three continents.

What We Are Reading Today: ‘The Social Wasps of North America, Central America, and the Caribbean’

Author: Chris Alice Kratzer 

Social wasps like hornets and yellowjackets use the power of teamwork to build complex societies and architectural wonders, and though they comprise only a fraction of the thousands of species in North and Central America, they are almost solely responsible for giving wasps a bad reputation.

This beautifully illustrated field guide covers all known species of social wasps from the high arctic of Greenland and Alaska to the tropical forests of Panama and Grenada.

What We Are Reading Today: ‘Dinosaur Behavior’ by Michael J. Benton

Paleobiology has advanced from a speculative subject to a cutting-edge science. Today, researchers are applying the latest forensic technologies to the fossil record, revealing startling new insights into the lives of dinosaurs.

This illustrated guide explores the behavior, evolution, physiology, and extinction of dinosaurs, taking readers inside the mysterious world of these marvelous animals.

With specially commissioned illustrations by Bob Nicholls, “Dinosaur Behavior” explains how the dinosaurs lived and courted, fought and fed, signaled and interacted with each other, and much more.

What We Are Reading Today: ‘Orientalism’ by Edward Said

  • This binary framing, Said argues, has historically shaped Western attitudes and policies toward the Middle East, Asia, and North Africa, with effects that persist today

Author: Edward Said

Edward Said’s “Orientalism” is a landmark work that reshaped the understanding of how the West perceives and portrays the East.

First published in 1978, the book is a critique of the constructed image of the “Orient” as an exotic, monolithic “other,” created by the West to assert cultural and political dominance.

Through a meticulous examination of literature, art, and academic scholarship, Said reveals how this distorted portrayal served to justify colonial rule and perpetuate stereotypes.

Central to Said’s argument is the idea that orientalism is not merely a scholarly discipline but a political and cultural discourse used to reinforce Western superiority. He illustrates how this discourse characterizes the East as irrational, backward, and static, contrasting it with a rational and progressive West.

This binary framing, Said argues, has historically shaped Western attitudes and policies toward the Middle East, Asia, and North Africa, with effects that persist today.

Said’s interdisciplinary approach draws on history, literature, and politics, making “Orientalism” a rich and provocative analysis. He sets out how even seemingly objective academic studies and media representations have reinforced reductive stereotypes, showing how power shapes knowledge. By doing so, he challenges readers to critically examine the narratives they encounter about the “East.”

Although “Orientalism” is deeply rooted in historical context, its relevance endures in contemporary discussions of cultural representation and global politics. It continues to resonate in a world where stereotypes and biases influence international relations and public perception.

Said’s writing is both rigorous and accessible, blending scholarly depth with a moral clarity that makes his arguments compelling. While the book’s density may challenge some readers, its insights are invaluable for understanding how cultural narratives are constructed and used to assert dominance.

Ultimately, “Orientalism” is a profound critique of the structures that perpetuate inequality and division. It remains an essential read for anyone seeking to understand the cultural legacies of imperialism and the enduring power of representation.

Said’s work is not only an academic achievement but also a call to rethink entrenched attitudes and strive for a more equitable understanding of cultural difference.

What We Are Reading Today: ‘The Difference’ by Scott E. Page

In this landmark book, Scott Page redefines the way we understand ourselves in relation to one another. 

“The Difference” is about how we think in groups—and how our collective wisdom exceeds the sum of its parts. 

Why can teams of people find better solutions than brilliant individuals working alone? And why are the best group decisions and predictions those that draw upon the very qualities that make each of us unique? The answers lie in diversity—not what we look like outside, but what we look like within, our distinct tools and abilities.
