Ape to Man (History Channel) (2005) Review

I teach Intro to Anthropology at a local community college, and showed this in class last week. The students were engaged throughout, which is quite a feat, considering it's a 9:30am class. The information is factual, and the acting is only a little over the top. A great way to introduce students to the ideas behind human evolution, and to walk them step by step through the discoveries we've made in the past century. I would recommend it for high school and college classes.

It has long been considered the most compelling question in our history: Where do human beings come from? Although life has existed for millions of years, only in the past century-and-a-half have we begun to use science to explore the ancestral roots of our own species. The search for the ultimate answer has taken a number of twists and turns, with careers made and broken along the way. APE TO MAN is the story of the quest to find the origins of the human race - a quest that spanned more than 150 years of obsessive searching The search for the origins of humanity is a story of bones and the tales they tell.It was in 1856 that the first bones of an extinct human ancestor were encountered, unearthed by a crew of unskilled laborers digging for limestone in Western Europe. The find, which would be known as Neanderthal Man, was seeing the light of day for the first time in more than 40,000 years. At the time, the concept of a previous human species was virtually unthinkable.Yet just a few years later, Charles Darwin's work The Origin of Species first broached the subject of evolution, and by the end of the nineteenth century, it had become the hottest topic of the age.Adventurers had embarked on the search for the Missing Link, the single creature that represented the evolutionary leap from apes to humans.APE TO MAN examines the major discoveries that have led us to the understanding we have today, including theories that never gained full acceptance in their time, an elaborate hoax that confused the scientific community for years, and the ultimate understanding of the key elements that separate man from apes.

Human Family Tree (2009) Review

Human Family Tree (2009)

The National Geographic Society research on the Genographic Project is a genetic analysis of the human species origin in Africa and its spread throughout the world. Using samples, the lab results tell a story of the many branchings of the human tree. From the mitochondrial DNA, the researchers found that everyone in the world descends from one women in Africa some 150,000 to 200,000 years ago, while using the Y-chromosome they found we all descend from one man some 70,000 years ago. Mutations created branches through time in both areas and these are used to show the basic migration routes for the people, through their genes.
That these branches happened appears to be well researched. However, the researchers give approximate dates for these events and that is an area open to question. Is it really 150,000 or is it 1.5 million years ago for the scientific "Eve"? One issue glossed over is that the genetic evidence is not matching well with the archaeological and human paleontological data. For example, the genetic data showed a date of 15-20,000 years ago for the peopling of the New World and assumes that Clovis people were the first. How then are the dozens of well-dated sites in South America from 30,000+ years going to fit the genetic model. One statement was potentially wrong, when they said that Native Americans were isolated until Columbus. This negates the Viking settlement in Labrador, Canada, as well as possible contact with Chinese. The Eskimo and Aleut who came later to America are also not included.
Another issue that needs to be discussed better in this film is that Europe and Asia were well occupied about a million years ago, and that genetic links between Homo erectus fossils in China and modern Asians exist in their shovel-shaped incisors. Similarly, some of the Java Homo erectus specimens show traits still found there. Clearly, those populations today have some ancestors who did not migrate out of Africa some 70,000 years ago. Researchers also are still debating if Neanderthals left their genes in us.
Going back to 150,000 years ago and assuming 25 years per generation, each of us had 2 to the 6000th power ancestral lines in our massive genealogy. (Two to the 30th power is a billion!) This film portrays only two of those lines.
The film is well worth seeing. However, in many ways it contains the fallacy of extrapolation because it looks only at those two lines. Nevertheless, an important point made repeatedly in the film is that we are all cousins in the human family and that research on the great chain of being is worthwhile. I ordered my kit today from National Geographic.

Evolution Boxed Set (2001) Review

Evolution Boxed Set (2001)
Average Reviews:

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.

Galapagos (2007) Review

Galapagos (2007)
Average Reviews:

(More customer reviews)
This Blu-ray DVD has not had the hype that the Planet Earth series has had, but it rivals the series even within its limited content and definitely surpasses it in sound/editing.
This BBC series is broken into several episodes, all of which are well balanced with scientific information and amazing visuals of the Galapagos. Some episodes focus more above sea, others below, and yet others on the human interface with the islands.
The narration is top notch and the sound effects and music are beautiful - combined they really make this DVD shine. You definitely get a lot of bang for the buck on this DVD because it is a highly polished production.

The inspiration for Darwin's theory of evolution, the Galapagos Islands are a living laboratory, a geological conveyor belt that has given birth to and seen the death of many species of plants and animals. As the western islands rise up from the sea offering a chance of life, the eastern islands sink back beneath the waves guaranteeing only death. Between the two are the middle islands; fertile, lush land in its prime that contains an incredible diversity of life. Nowhere else on the Earth are the twin processes of creation and extinction of species so starkly apparent... see it all unfold before your eyes in this stunning series filmed entirely in high definition from the BBC and the National Geographic Channel.

Orangutan Island - Season 1 (2008) Review

Orangutan Island - Season 1 (2008)
Average Reviews:

I love monkeys and apes, I'll be the first to admit. But bias aside, this is, I think, one of the BEST shows that was on TV. And the whole family can enjoy it!
Orangutans, one of our closest living relatives, are critically endangered. Deforestation and poaching are bringing their numbers dangerously close to a point of no return. When a parent dies, usually the young orangutan would follow shortly after. However, the classmates of Nyaru Mentang have been rescued and are raised by humans in hopes of releasing them into the wild. This is a long process, as the dependency period of a baby orang on it's mother is the longest in the mammalian family, aside from humans.
The show is always good for a laugh, and I find it always makes me smile, no matter my mood going into it. Most of it is pretty happy, though there are sad parts of the episodes, and some of the stories about the orangutans are heartbreaking. Take Bonita for instance - poachers shot her mother out of a tree, and she clung to her mother's hair on the way down. After mother and child hit the ground, the poachers came and literally ripped her away from her dead mother, most likely to be sold into a life of solitary confinement in a cramped cage.
Within a couple episodes you'll get to know the orangutans, and learn to appreciate and understand their complex social structure, and their quirks. Each is very distinctive and has a readily discernible personality.
Watching them, one can't help but feel like you are looking at people. They think, they plan, they ponder, they trick, they scheme, they cry, they laugh, they love (two romances start up during season 1!!). These intelligent and gentle creatures will easily capture your heart, and you'll find that each episode ends much too quickly.

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.

It is a clever, educative, informing work of the past-in-the-future Earth of which extinction of homo sapiens is just a next step of evolution regardless of Kyoto-Copenhagen-alike fairy-talks.
A mondo-doco-style movie is well done technically, combining animation with doco of life surrounding while navigating along sequences of a feature and extras.
Highly recommended.
