Latest Phylogenetics Stories
A free online collaborative encyclopedia which aims to document all of the 1.8 million living species known to science has hit 170,000 entries so far.
A team of Penn State scientists has shed light on the processes that lead to certain human DNA mutations that are implicated in hundreds of inherited diseases such as tuberous sclerosis and neurofibromatosis type 1.
Detailed, accurate evolutionary trees that reveal the relatedness of living things can now be determined much faster and for thousands of species with a computing method developed by computer scientists and a biologist at The University of Texas at Austin.
Researchers at the University of Leeds have devised a more accurate method of dating ancient human migration â€“ even when no corroborating archaeological evidence exists.
Scientists are compiling an Internet-based observatory of life on Earth as a guide to everything from the impact of climate change on wildlife to pests that can damage crops.
During a seminar at another institution several years ago, University of Chicago paleontologist David Jablonski fielded a hostile question: Why bother classifying organisms according to their physical appearance, let alone analyze their evolutionary dynamics, when molecular techniques had already invalidated that approach?
Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular level tend to produce incorrect results.
Biologists all over the world are working on an effort to determine how all the estimated 500,000 species of plants are related to one another.
A new University of Florida study based on DNA analysis from living flowering plants shows that the ancestors of most modern trees diversified extremely rapidly 90 million years ago, ultimately leading to the formation of forests that supported similar evolutionary bursts in animals and other plants.
Scientists at Penn State have developed a new computational method that they say will help them to understand how life began on Earth.
