Charles darwin and the tree of life bbc download.Charles Darwin and the Tree of Life - David Attenborough
Attenborugh ascribed all of the controversial subjects related to Evolution and Darwin's ideas at those years. The visual expression is very strong as well as the narration. I don't recommend this documentary for people who has counter ideas of Evolution Theory. For the rest, i strongly recommend to watch it again and again. Details Edit.
Release date February 1, United Kingdom. United Kingdom. Official BBC site. Why do we think he was right? And why is it more important now than ever before? David starts his journey in Darwin's home at Down House in Kent, where Darwin worried and puzzled over the origins of life. He goes back to his roots in Leicestershire, where he hunted for fossils as a child and where another schoolboy unearthed a significant find in the s, and he revisits Cambridge University, where both he and Darwin studied and where many years later the DNA double helix was discovered, providing the foundations for genetics.
At the end of his journey in the Natural History Museum in London, David concludes that Darwin's great insight revolutionised the way in which we see the world. We now understand why there are so many different species, and why they are distributed in the way they are. But above all, Darwin has shown us that we are not set apart from the natural world and do not have dominion over it.
We are subject to its laws and processes, as are all other animals on earth to which, indeed, we are related. Follow evolution and explore the variety of life with the interactive Tree of Life.

The weird future of life on Earth The fact of evolution implied something about how life began. How did life begin? That takes us back to Darwin.
A letter to a friend Darwin never wrote about how life began in his books, but he did speculate about it in private. Darwin was proposing that life began, not in the open ocean, but in a smaller body of water on land. Related Documentaries. The Blob: A Genius without a Brain. Bat Superpowers.

The great naturalists that preceded him Linne, Cuvier, Blumenbach, and Lamarck all placed humans in the natural order, and the wide variety of new species of plants and animals, and new varieties of humans, confronting Europeans on their voyages of discovery and conquest, scientific research came to center on what was referred to as the species question.
What could explain the rich variety of species found in the world? Why is there such variety to a divinely created and designed world?
If the variety of nature was too great to allow one to answer these questions, then humans could serve as a model. If we could understand why humans vary, then we would have the key to the species question. Advocated most vigorously by a group of naturalists and doctors that came to be known as the American School, the polygenic theory of human origins was used by many as a scientific justification for slavery and used against the abolitionists who often turned to the Biblical account of humans as having one single origin, or monogenesis, to support their cause.
Although Darwin's work is often associated with the challenge it posed to Christian doctrine, this was not the opponent Darwin had in mind when he wrote the Origin of Species.
His scientific intervention was against the polygenic theory and its implicit justification of slavery. To do this, Darwin proposed a scientific, and not religious, monogenic theory of the origin and variation of species. Although humans are not mentioned at all in the work, its argument led to an unavoidable conclusion that humans are one species. The scientific foundation for slavery was ripped away, much to Darwin's satisfaction. Essays collected between and The essays include efforts in constructive literary theory, theoretical polemics, practical literary criticism, quantitative literary study, and intellectual history.
The constructive theory includes 1 a model of human nature that integrates basic motives, basic emotions, and features of individual identity; 2 a theory of literary meaning as the interplay of perspectives among authors, readers, and characters; and 3 arguments on the adaptive function of literature and the other arts.
Polemics include analysis of the underlying motives and assumptions in both traditional humanism and poststructuralism. There are two essays in quantitative literary study, both from a website questionnaire study on the organization of characters in 19th-century British novels.
One summarizes results of the study as a whole. The other offers a quantitative analysis of Hardy's Mayor of Casterbridge. Nathalie Gontier. David N. Richard Burian. Ever since Darwin, the familiar genealogical pattern known as the Tree of Life has been prominent in evolutionary thinking and has dominated not only systematics, but also the analysis of the units of evolution.
However, recent findings indicate that the evolution of DNA, especially in prokaryotes and in such DNA vehicles as viruses and plasmids, does not follow a unique tree-like pattern. Because evolutionary patterns track a greater range of processes than those captured in genealogies, genealogical patterns are in fact only a subset of a broader set of evolutionary patterns. This fact suggests that evolutionists who focus exclusively on genealogical patterns are blocked from providing a significant range of genuine evolutionary explanations.
Consequently, we highlight challenges to tree-based approaches, and point the way toward more appropriate methods to study evolution although we do not present them in technical detail.
We argue that there is significant benefit in adopting wider range of models, evolutionary representations and evolutionary explanations, based on an analysis of the full range of evolutionary processes. On this basis, we seek to promote the study of especially prokaryotic evolution with dynamic evolutionary networks, which are less constrained than a TOL, and to provide new ways to analyze an expanded range of evolutionary units genetic modules, recombined genes, plasmids, phages and prokaryotic genomes, pangenomes, and microbial communities , and of evolutionary processes.
Finally, we discuss some of the conceptual and practical questions raised by such network-based representation. Scarlett Baron. Aramis Balde. Stefano Dominici. Ricardo Rozzi. Yannis Kanarakis.
