Timetree of Life
Scientists and non-scientists now have easy access to information about when living species and their ancestors originated, information that previously was difficult to find or inaccessible. Free access to the information is part of the new Timetree of Life initiative developed by NAI’s Blair Hedges, professor of biology with the Penn State Astrobiology Research Center, and Sudhir Kumar, a professor of life sciences at Arizona State University.
The Timetree of Life project debuted with the simultaneous release of a book titled The Timetree of Life (Oxford University Press), which is written by a consortium of 105 experts...

Assembling the Tree of Life
Unique scientific endeavors, ranging from whole genome sequencing to studies on lateral gene transfer, are transforming the science of biology in the 21st century. All of this data requires new ways of organizing information in an evolutionary context. The goal of the NSF’s Assembling the Tree of Life activity is to help facilitate the effort of organizing data on all 1.7 million described species of organisms thus far. The NSF recently announced its intention to support “creative and innovative research that will resolve evolutionary relationships for large groups of organisms throughout the history of life.” The...Source: [NSF]
