Dating Methodology. Tree of Life Web Project. The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world.
On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things. 3 - The Origin of Life Made Easy (by potholer54) Origin of Eukaryotes Cells. Rediscovering Symbiogenesis. Last month, we published Symbiogenesis: A New Principle of Evolution by Soviet-era Russian botanist Boris Kozo-Polyansky.
Part scientific treatise, part historical detective work, the book resurrects a lost classic of evolutionary theory along with its fascinating backstory. The volume’s co-editors, Victor Fet and Lynn Margulis, argue that Kozo-Polyansky’s theories—now recognized as true by almost all biologists after decades of neglect—were far ahead of their time. Here, editor and translator Fet tells the story of Kozo-Polyansky’s discovery. Discover Interview: Lynn Margulis Says She's Not Controversial, She's Right. Symbiogenesis Basics. LUCA. By Michael Marshall ONCE upon a time, 3 billion years ago, there lived a single organism called LUCA.
It was enormous: a mega-organism like none seen since, it filled the planet’s oceans before splitting into three and giving birth to the ancestors of all living things on Earth today. This strange picture is emerging from efforts to pin down the last universal common ancestor – not the first life that emerged on Earth but the life form that gave rise to all others. Invictus.
