Race has provided the rationale and excuse for some of the worst atrocities in human history. Yet, according to many biologists, physical anthropologists, and geneticists, there is no valid scientific justification for the concept of race. To be more precise, although there is clearly some physical basis for the variations that underlie perceptions of race, clear boundaries among "races" remain highly elusive from a purely biological standpoint.

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.

This serves as the second book in the Basics of Biology series. In this segment, the functions of membranes are explored. With regards to fully understanding biological organisms, the cell membrane is essential to developing an understanding of how cell function to control the substance that enter and exit them along with they way in which they interact with their environment.

The ocean teems with life that thrives under difficult situations in unusual environments. The Extreme Life of the Sea takes listeners to the absolute limits of the ocean world - the fastest and deepest, the hottest and oldest creatures of the oceans. It dives into the icy Arctic and boiling hydrothermal vents - and exposes the eternal darkness of the deepest undersea trenches - to show how marine life thrives against the odds. This thrilling book brings to life the sea's most extreme species, and tells their stories as characters in the drama of the oceans.

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.

Hear a day in the life of the Amazonian rainforest, a continuous sequence of beautiful and exotic sounds.

Most of us think of bugs as pesky creatures we squish under our shoes or bat away with our hands. Under the microscope of Sue Hubbell’s keen eye emerges an exciting world we rarely take the time to see. Author of A Country Year, Hubbell writes regularly for The New Yorker, Smithsonian, and Discover magazines, bringing to her delightful essays the practical veracity of a gentlewoman farmer, and the style and élan of an eccentric who has found her bliss.

Vi går gennem hele livet i en og samme krop, og alligevel ved de fleste af os stort set intet om, hvordan vores krop fungerer, og hvad der sker inden i os. Dette gør den formidable videnskabsformidler Bill Bryson, forfatter til bl.a. bestselleren "En kort historie om næsten alt", noget ved. I "Kroppen - en guide for indehavere" tager han os med på en dybt fascinerende rejse fra top til tå og anskueliggør det vidunder, vores legeme er.

In questo audiolibro viene affrontato il genoma umano, analizzando scientificamente le sue caratteristiche: dna, nucleo, citoplasma, cellula, organuli e mitocondri. Buona ascolto!

Throughout the ages, human beings have had a profound fascination with the natural world. It has influenced all aspects of our civilisation, from science and religion to music, art, literature and film. These 12 episodes, taken from Radio 4's epic series Natural Histories, find presenter Brett Westwood exploring two major groups of animals - fish, who have lived on Earth for over 450 million years, and invertebrates, who make up 97 percent of all species worldwide - to find out how our perception and representation of them has changed over time.

A fun way to expand your knowledge with facts about the human body.

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.

Las hormigas se nos muestran en este libro como seres capaces de extraordinarias proezas. como el hombre, también ellas cuentan con ejercicios organizados. algunas se han especializado en una suerte de ganadería y otras parecen hacer aprendido a cultivar sus alimentos. su sistema de comunicación también despierta el asombro y nos recuerda a la telepatía. en la vida de las hormigas, Maurice Maeterlinck, premio nobel de literatura, hace gala de su interés entomológico.

人はまちがえる。それは、どんなにがんばっても、脳がまちがいを生み出すような情報処理を行っているから。

In Star Trek, crew members travel to unusual planets, meet diverse beings, and encounter unique civilizations. Throughout these remarkable space adventures, does Star Trek reflect biology and evolution as we know it? What can the science in the science fiction of Star Trek teach us? In Live Long and Evolve, biologist and die-hard Trekkie Mohamed Noor takes fans on a fun, fact-filled scientific journey. Noor offers Trekkies, science-fiction fans, and anyone curious about how life works a cosmic gateway into introductory biology.

Bedbugs. Few words strike such fear in the minds of travelers. In cities around the world, lurking beneath the plush blankets of otherwise pristine-looking hotel beds, are tiny, bloodthirsty beasts just waiting for weary wanderers to surrender to vulnerable slumber. Though bedbugs today have infested the globe, the common bedbug is not a new pest at all. Indeed, as Brooke Borel reveals in this unusual history, this most-reviled species may date back over 250,000 years.

As human beings, we are fascinated by what makes us tick. We know that nature gave us certain biological appetites to ensure our survival, among those the need for water, food, sex, and love, but meeting these alone is not enough to ensure happiness. Scientists, and now managers, are realizing that people have a biological need to experience social rewards like praise, the thrill of innovation, and the satisfaction of acquiring new skills.

If we are, in part, a product of our genes, can free will exist? Incisive and engaging, this indispensable tour of evolutionary biology runs the gamut of contemporary debates, from science and religion to our place in the universe.
