Latest Phylogenetics Stories
Scientists have analyzed the genomes of humans and closely related primates and discovered over 500 regulatory regions that chimpanzees and mammals have that humans do not.
With the genetics of so many organisms that have different traits yet to study, and with the techniques for gathering full sets of genetic information from organisms rapidly evolving, the "forest" of evolution can be easily lost to the "trees" of each individual case and detail.
The scientists who put an innovative tree of life online last year now have made that same resource available -- free -- for smartphones.
The initial peopling of North America from Asia occurred approximately 15,000-18,000 years ago, however estimations of the genetic diversity of the first settlers have remained inaccurate.
A lesson from flashy Central American warblers.
A new "tree of life" has been constructed by researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech for the gamma-proteobacteria, a large group of medically and scientifically important bacteria that includes Escherichia coli, Salmonella typhimurium, and other disease-causing organisms.
Finds that cells without mitochondrial fusion have less mtDNA, more mutations in their mtDNA, and less ability to tolerate those mutations.
New evidence that specialized adaptations are not evolutionary dead ends.
Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent.
A team of Spanish and Portuguese researchers has carried out molecular genetic analysis of the Y chromosome (transmitted only by males) of the aboriginal population of the Canary Islands to determine their origin and the extent to which they have survived in the current population.
