Ornithoscelida Rises: A New Family Tree for Dinosaurs - Scientific American (blog)


Scientific American (blog)
Today sees the publication of a significant new technical paper on dinosaur phylogeny. And it's a game-changer or watershed study, one of those that will get cited a phenomenal amount and result in a distinct pre- and post-2017 marker in the literature.

Dinosaur Phylogeny Gets “Radical Shakeup,” Requiring Convergent Evolution - Discovery Institute


Discovery Institute
A paper in Nature, “A new hypothesis of dinosaur relationships and early dinosaur evolution,” presents fresh ideas about dinosaur relationships that reveal the extent to which dinosaur traits are not distributed in a treelike pattern. One news article ...

Bacterial (Prokaryotic) Phylogeny

Hamilton, Ontario - Canada

Prokaryotic organisms were the sole inhabitants of this planet for the first 2-2.5 billion years. To understand such fundamental questions as the nature and origin of the first cell, origin of different types of metabolism, information transfer processes, photosynthesis, origin of the eukaryotic cells, evolution of disease-causing as well as beneficial microbes, a sound understanding of the bacterial (prokaryotic) evolution is essential. The analyses of genome sequence data using new approaches are providing valuable insights in understanding some of these most ancient and important aspects of the evolutionary history of life. This website, presents information using novel comparative genomic approaches, that are helpful in understanding the following critical issues in bacterial/prokaryotic phylogeny:
