Latest Phylogenetics Stories
A new online Encyclopedia of Life debuted yesterday, but quickly crashed on its first day of operation after its servers were overwhelmed by the high numbers of visitors to the site.
The first 30,000 pages of a massive online Encyclopedia of Life were unveiled today at the prestigious Technology, Entertainment and Design (TED) Conference in Monterey, California.
Did modern birds originate around the time of the dinosaurs' demise, or have they been around far longer? New research offers the strongest molecular evidence yet for an ancient origin of modern birds.

By Manos, Paul S Soltis, Pamela S; Soltis, Douglas E; Manchester, Steven R; Et al Abstract.- It is widely acknowledged that integrating fossils into data sets of extant taxa is imperative for proper placement of fossils, resolution of relationships, and a better understanding of character evolution.
By Yesson, C; Culham, A Abstract.- We investigate the impact of past climates on plant diversification by tracking the "footprint" of climate change on a phylogenetic tree.
The Tree of Life is flourishing. The Web-based project, a massive collaboration among scientists from all over the world, is growing more "leaves" and "branches" all the time.
A recent debate over the usefulness and relevance of the widely used Biological Species Concept, based on reproductive isolation, versus the Phylogenetic Species Concept, which is centred around identifying the smallest group with common ancestry, has raised concerns that changing nomenclatural foundations might result in the appearance of previously unrecognized patterns of biodiversity.
Human evolution, University of Chicago researchers report, is still under way in what has become our most important organ: the brain. In two related papers, published in the September 9, 2005, issue of Science, they show that two genes linked to brain size are rapidly evolving in humans.
In a study published in the September issue of The American Naturalist, T. Jonathan Davies (Imperial College London) and colleagues use a phylogenetic tree of the iris family to show that lineages within the Cape have speciated at a faster rate than those found elsewhere, even in comparison to regions of similar Mediterranean climates.
