Evolution & Genetics

In Nature's Genius David Farrier takes us on a profound journey into this ever-changing natural world. What we discover could change us. The ways animals adjust to the urban landscape can help us design sustainable cities. Examining other intelligences can help us remake our economies. Learning from bacterial evolution may help solve our waste problem. Synthetic biology could rescue animals from the brink of extinction. Thinking in timescales of the natural world could help us choose a better future.

Daughter. Duhitár-. Dustr. Dukte. Listen to these English, Sanskrit, Armenian and Lithuanian words, all meaning the same thing, and you hear echoes of one of history’s most unlikely journeys. All four languages—along with hundreds of others, from French and Gaelic, to Persian and Polish—trace their origins to an ancient tongue spoken as the last ice age receded. This language, which we call Proto-Indo-European, was born between Europe and Asia and exploded out of its cradle, fragmenting as it spread east and west.

In recent years, genetic testing has become easily available to consumers across the globe, making it relatively simple to find out where your ancestors came from. But what do these test results actually tell us about ourselves? In Ancestors, Pierre Zalloua, a leading authority on population genetics, argues that these test results have led to a dangerous oversimplification of what one’s genetic heritage means. Genetic ancestry has become conflated with anthropological categories such as “origin,” “ethnicity,” and even “race” in spite of the complexities that underlie these concepts.

Being human entails an astonishingly complex interplay of biology and culture, and while there are important differences between women and men, there is a lot more variation and overlap than we may realize. Sex Is a Spectrum offers a bold new paradigm for understanding the biology of sex, drawing on the latest science to explain why the binary view of the sexes is fundamentally flawed.

Despite efforts to sustain civilization, humanity faces existential threats from overpopulation, globalized trade and travel, urbanization, and global climate change. In A Darwinian Survival Guide, Daniel Brooks and Salvatore Agosta offer a novel—and hopeful—perspective on how to meet these tremendous challenges by changing the discourse from sustainability to survival. Darwinian evolution, the world’s only theory of survival, is the means by which the biosphere has persisted and renewed itself following past environmental perturbations, and it has never failed, they explain.
