Biology Genetics

John Tyler Bonner, one of our most distinguished and insightful biologists, here challenges a central tenet of evolutionary biology. In this concise, elegantly written book, he makes the bold and provocative claim that some biological diversity may be explained by something other than natural selection. With his customary wit and accessible style, Bonner makes an argument for the underappreciated role that randomness - or chance - plays in evolution.

Imagine being able to consume 250,000 calories daily without gaining weight. If you had the metabolism of a shrew you could. And while most of us can't hold our breath for more than a few minutes, the Weddell seal can remain underwater for a full 75 minutes! Through many amazing examples this audio discusses the mechanisms humans and other creatures have evolved to maintain survival needs.

Asserting that religious creeds and philosophical questions can be reduced to purely genetic and evolutionary components, and that the human body and mind have a physical base obedient to the laws of physics and chemistry, Genesis demonstrates that the only way for us to fully understand human behavior is to study the evolutionary histories of nonhuman species. Of these, Wilson demonstrates that at least 17 - among them the African naked mole rat and the sponge-dwelling shrimp - have been found to have advanced societies based on altruism and cooperation.

DNA serves as the basic instruction manual for life. In this installment, we look at the way in which DNA is structured, replicated, and how it is packaged into such a small area. This will provide the basic understanding of how genes are structured in an easy to understand way.

The zombie has had a bit of a renaissance over the last decade. Hollywood churns out films like World War Z and TV shows like The Walking Dead, and communities throughout the country hold zombie runs and races. So what’s driving the zombie obsession? Where did the fear of this creature originate? In this audiobook, The Real Zombies of Nature, we look at the myth of the zombie versus real instances of zombification in the natural world and engage in some scientific speculation about what would happen if myth ever became reality.

This gives a brief and quick overview of evolutionary theories of the origins of early life at the microscopic levels and the view of how organic substances can come from inorganic substances.
