Evolution Boxed Set (2001) Review

Everybody knows that when it comes down to the final question in a game of Trivial Pursuit that they should make me try and answer a science question because I know pretty much nothing about science and nature. This is because the one thing I knew about high school biology was that you dissected animals and being sick in front of the smartest girls in school did not appeal to me at all. So I took Life Through the Microscope (it involved drawing) and Ecology (it was the only class that fit my schedule) and missed out on Biology, Chemistry and Physics. However, since I did my dissertation on the infamous Scopes "Monkey" Trial I do have something of an interest in the controversy over evolution if not the concept itself. This seven-part series exploring various facets of evolution was perfect so someone like me who insists on having theory of any sort mixed with a heavy dose of practice.
"Evolution" is as much about the profound impact the evolutionary process has had on our understanding of the world around us as it is on the various versions of the theory that have been expounded in scientific textbooks for the past century. The series basically focuses on five key concepts regarding evolution, sandwiched between episodes that constitute a dramatic introduction and a controversial coda:
"Darwin's Dangerous Idea" offers dramatizations of key moments in Darwin's life along with contemporary talking heads explaining the profound implications of the evolutionary theory and the place it holds in the scientific community today as a pivotal concept. It takes a while to adjust to the episodic approach of the dramatizations, which come and go without a real sense of regularity, but since they dramatized the famous retort of Huxley to Bishop Wilberforce and other key moments in the popularization of evolution there is a certain effectiveness to it all. What you get from this episode is a better idea of what the initial complaints were to evolutionary theory and who was making them.
"Great Transformations" explores the evolutionary changes that caused the incredible diversity of animal life that exists on earth. The focus is on the development of the four-limbed body plan, which is explained in the context of how animal life moved from water to land and eventually to human beings, thereby answering the key question of why are human connected to all life.
"Extinction!" represents the flip side of evolutionary transformations, explaining the how and why behind the fact that 99.9 percent of all species that have ever lived on earth are now extinct. This leads to the provocative question as to whether human beings are going to cause the next mass extinction on the planet.
"The Evolutionary Arms Race" puts the entire concept of natural selection and survival of the fittest in the context of humanity's battles with microorganisms, looking at a case study regarding the reemergence of tuberculosis in Russian prisons. With the alarming spread of resistance among pathogens that cause disease, the episode explains how this particular "race" offers the major threat to human existence. The scary question here is whether we are fighting a battle we cannot win.
"Why Sex?" makes the contention that in evolutionary terms sex is more important than life itself. But on a more pragmatic level is addresses the question of whether males are necessary to perpetuate the species, looking at a wide variety of case studies drawn from nature. This episode also explains the principle of monogamy in evolutionary terms.
"The Mind's Big Bang" addresses the question of why humans are the dominant species on earth. The answer is found in the past, when something happened to primitive humans to trigger a creative, technological, and social explosion, which ultimately allowed humans to dominate the planet. The episode tries to uncover (literally) the primitive forces that contributed to the emergence of the mind of the modern human being.
"What About God?" is the coda to the series in that it returns to the initial question of Darwin's day regarding the conflict between evolution and religion. The debate is presented within the context of a college student whose family is not happy with what he is learning about evolution at Wesleyan College, a group of high school students trying to get their local school board to allow the teaching of creationism, and the activities by adults on both sides of the question to win this pivotal battle. I consider the episode to be remarkably even-handed, but then I do not think there is an inherent conflict between the two, which invalidates my opinion for true believers on both sides.
Overall I like the fact that "Evolution" goes for depth rather than breadth. The case studies, at least to my uneducated mind, come across as being representative of the issue under discussion. The DVD series also features access to the Evolution Web site with its interactive games, activities, and biographies, so those who would like to get additional information and insight on any one of these topics can easily do so. There are also student lessons for teachers who want to work these episodes into their science classes and a printable teacher's guide (remember, "Evolution" was produced by WGBH Boston, which means we are talking--surprise--public television).

Evolution offers a groundbreaking and definitive view of the extraordinary impact the evolutionary process has had on our understanding of the world around us. Beginning with Darwin s revolutionary theory, this seven-part series explores all facets of evolution the changes that spawned the tree of life, the power of sex, how evolution continues to affect us every day, and the perceived conflict between science and religion. Includes:Darwin s Dangerous Idea: Interweaving key moments of drama in Darwin's life with current research, Darwin s Dangerous Idea explores why his theory of evolution might matter even more today than it did in his own time.Great Transformations: From the development of the four-limbed body plan, the journey of animal life from water to land, and the emergence of humans, Great Transformations focuses on the important evolutionary changes that triggered the earth s incredible diversity.Extinction!: Some 99.9 percent of all species that have ever lived on earth are now extinct. Extinction! explores why, then confronts a frightening notion: Are humans causing the next mass extinction the sixth in the history of life on earth?The Evolutionary Arms Race: Survival of the fittest: Is it raw competition, a level of cooperation indispensable to life, or both? Explore our own spiraling arms race with microorganisms the only real threat to our existence and trace the alarming spread of resistance among pathogens that cause disease.Why Sex?: Investigate the endless variety of sexual expression and the powerful hold sex exerts over almost all living things. And discover why, in evolutionary terms, sex is more important than life itself.The Mind s Big Bang: Between 100,000 and 50,000 years ago, something happened that triggered a creative, technological, and social explosion, allowing humans to dominate the planet. What forces may have contributed to the emergence of the modern human mind?What About God?: Of all the species on earth, only humans try to explain who they are and how they came to be. Encounter real human stories of people struggling to find a balance between religion and science, realms that play very different roles in assigning order to the universe and a purpose to life.

Charles Darwin and the Tree of Life (2009) Review

Charles Darwin and the Tree of Life (2009)
Average Reviews:

(More customer reviews)
Charles Darwin and the Tree of Life is an outstanding celebration of the life and ideas of one of the greatest scientists yet to live. This nearly one-hour film includes a close look at the importance of both descent with modification and the common ancestry of all life. Wonderful glimpses at Darwin's original specimens and notes, important fossils, and DNA evidence are also high-lighted. These are all connected nicely into an easy to follow description of the primary mechanism of evolution, natural selection.
Weaved seamlessly throughout is natural history film footage shown of David Attenborough's many earlier television series. By using this footage, the film apply demonstrates the diversity of life and celebrates the work of perhaps the greatest natural history television series writer, director, and producer (Planet Earth, Life on Earth, and many other series).
I have used this film successfully with my high school biology classes. It provides a clear, direct, and articulate look at a 21st century, evidence based understanding of evolution and the foundational role that Darwin's work has played. This film is indeed a fitting tribute to Darwin on the 200th anniversary of his birth.

A personal insight, from the world's favourite naturalist, into Darwin's theory of evolution, exploring why it is more important now than ever before. Beautifully shot, this is the start of a series of celebrations of the man behind the theory that changed the world's thinking. But more than that, this is a labor of love for a man who has been at the forefront of natural history programming or decades.

Half of all the world's domestic robots are now in Japan.
More than any trade deficit this robot deficit and the more important idea deficit that it dramatizes should be a source of concern to modern Americans.
By watching this program, you get to see a lot of technology that really is mind blowing from personal jet packs to cars that drive under water to energy sources that don't wreak havoc on the environment. This DVD is at one time a great example of gee whiz science and a resource manual for the types of projects we should be getting behind.
Throughout history true international power and influence have more often than not been led by societies who are on the cutting edge of emerging technologies and also by societies whose educational systems support such initiatives. This is a sad thought to contemplate as the United States now observes its first year in over forty years without having a manned space vehicle.
Sadly, while the technology may change over the years, the lesson imparted doesn't seem to in that those who fail to learn from history are often forced to repeat it.
