Review: Evolving Ourselves

Evolving Ourselves: How Unnatural Selection and Nonrandom Mutation are Changing Life on EarthEvolving Ourselves: How Unnatural Selection and Nonrandom Mutation are Changing Life on Earth by Juan Enriquez and Steve Gullans
My rating: 4 of 5 stars

This book explains the frontline research of contemporary genetics and then explores the potential in speculative science. Bridging the gap between science and science fiction, the culpability of the human race in modern evolution is outlined.

For four billion years, nature selected what lived and died. Life forms adapted by mutating randomly so that at least a few specimens sometimes hit the jackpot and survived . . . [Darwin] is not right anymore. Over the past century, as our species grew by billions, concentrated in cities, smartened, and domesticated itself and its surroundings, we became the fundamental driver of what lives and dies. . . Half the landmass on Earth is now covered by what humans want, not by what would naturally grow without the intervention of our species. Oceans, rivers, and lakes are depleted. In just a few centuries, we have terraformed, fertilized, fenced, seeded, and irrigated enormous sections of what was once forest, savannah, desert, and tundra to accommodate our plants, our animals, our wishes. This is unnatural selection.

There is much humans do not yet know as we dabble, such as the intricate interplay between the human genome, epigenome [turning on and off of gene expression], microbial biome [especially of the gut], and the barely researched virome [the viruses living off the host and the host’s bacterial flora]. Changes in any of these genomes affects not just the individual, but generations to come. We also do not yet understand the side effects of human domestication, such as explosions in rates of obesity, diabetes, allergies, and autism.

Entering the realm of speculative science and the future of humanity, this book also explores the future of human enhancement on athletics, and space travel and colonization. More questions are asked than answers given, but that is precisely what drives science into new realms.

I received this book through Goodreads’ First Reads Giveaway.
