The Great Courses: Biology

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

We use DNA routinely - to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future. But what, exactly is DNA, the self-replicating material present in nearly all living organisms?

When are we responsible for our own actions, and when are we in the grip of biological forces beyond our control? What determines who we fall in love with? The intensity of our spiritual lives? The degree of our aggressive impulses? These questions fall into the scientific province of behavioral biology, the field that explores interactions between the brain, mind, body, and environment that have a surprising influence on how we behave.

Your senses aren't just a part of you-they define you. Nothing you experience would be possible without the intricate power of your senses. But how much about them do you really know? Your ability to sense and perceive the world around you is so richly detailed and accurate as to be miraculous.

One of the greatest scientific feats of our era is the astonishing progress made in understanding biology-the intricate machinery of life-a progress to which the period we are living in right now has contributed the most.As you read these words, researchers are delving ever deeper into the workings of living systems, turning their discoveries into new medical treatments, improved methods of growing food, and innovative products that are already changing the world.

Four billion years ago, the infant Earth was a seething cauldron of erupting volcanoes, raining meteors, and hot noxious gases, totally devoid of life. But a relatively short time later-only 100 million to 200 million years-the planet was teeming with primitive organisms.What happened? Now you can find out-in a series of 24 vibrant lectures from a leader of the NASA-supported team studying the origins of life in the universe and also one of the nation's foremost science educators.

Published 150 years ago, Charles Darwin's On the Origin of Species - the text that introduced the world to natural selection - is among a handful of books that have changed the world. But the route to that status has been surprisingly circuitous and uncertain. Now, in 24 absorbing lectures by an award-winning teacher, you'll learn the remarkable story of Darwin's ideas, how scientists and religious leaders reacted to them, and the sea change in human thought that resulted.

In this series of 24 fascinating lectures, an acclaimed teacher and psychologist gives you a bio-psychological perspective on both the way we humans navigate and react to the world around us and an understanding of the ways in which that process is ever-changing.

In this series of 24 captivating lectures, an award-winning teacher and acclaimed scholar delves into the story of how, why, where, and when we became human. You'll gain a fresh understanding of the forces that have shaped our species, as Professor King synthesizes the best that more than a century of scientific scholarship has to offer across a variety of disciplines to gain the insights offered by fossils, ancient skeletal remains, and lifestyle information like cave art and stone tools.

Trying to understand our human origins has always been a fundamental part of who we are. Today, with the help of dramatic archaeological discoveries and groundbreaking advancements in technology and scientific understanding, we are closer than we've ever been to learning the true story. In recent decades, it has been the science of paleoanthropology that has led the investigation, helping us make sense of this controversial subject and providing us with a richer understanding of our origins.

This 24-lecture series is your guide to the latest information and viewpoints on what scientists know about this fascinating subject. Taught by an award-winning teacher whose training as a clinical psychologist straddles both the science of the mind and its impact on individual lives, their comprehensive approach reveals how that science applies to the life of our species - and to your own life as well. The lectures explore theories about how the mind works on both an evolutionary and individual scale.

Discover medical science's extraordinary journey from a time when even the slightest cut held the threat of infection and death to today's era of routine organ transplants and daily headlines about the mysteries of DNA and the human genome. What major discoveries made this transition possible? Who were the fascinating individuals responsible for those discoveries, and what qualities prepared each of them for their unique roles in medical history? These 12 compelling lectures draw on the lives of medicine's greatest contributors to tell the human story behind the development of Western scientific medicine.

What does it mean to be human? Where did we come from? And what unites us in our diversity today? Anthropology and the Study of Humanity is your chance to tackle these big questions as you survey one of the world's most engaging - and human - sciences. Taught by acclaimed professor and field researcher Scott M. Lacy of Fairfield University, these 24 wide-ranging lectures are the ideal guide through the world of anthropology, or the study of humanity across time and space.

In many ways, insects are just like us. Elaborate mating rituals, a variety of parenting styles, and a plethora of careers — from architects and engineers, to farmers and ranchers. Like us, they’re able to share complex information essential for survival, significantly impact their environment, and recycle. But insects outdo us in so many respects. They are terrestrial, but some can live underwater.
