June 8, 2015 — A study by biologists now provides evidence that, at the molecular level, evolution is both unpredictable and irreversible. The study focuses exclusively on the type of evolution known as purifying ... read more

June 8, 2015 — Scientists reconstruct the DNA of the Megaloceros from findings in caves in the Swabian Alb and discover possible causes for its later ... read more

June 4, 2015 — A fossil's age raises the possibility that the first animals to emerge from the water to live on land were large tetrapods in Gondwana in the southern hemisphere, rather than smaller species in ... read more

Eukaryotes: A New Timetable of Evolution

June 3, 2015 — The first single-celled organisms with a nucleus originated more than a billion years later than biogeochemical evidence had previously indicated. In contrast to prokaryotes such as bacteria, ... read more

June 1, 2015 — New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to ... read more

Ancient DNA Sheds Light on How Past Environments Affected Ancient Populations

May 28, 2015 — For the first time, a study shows that epigenetic marks on DNA can be detected in a large number of ancient human remains, which may lead to further understanding about the effects of famine and ... read more

May 22, 2015 — Genetic material from fungi collections helped a team of researchers resolve the mushroom 'tree of life,' a map of the relationships between key mushroom species and their evolutionary ... read more

May 22, 2015 — A new study of some primitive birds from the Cretaceous shows how several separate lineages evolved adaptations for diving. Living at the same time as the dinosaurs, Hesperornithiform bird fossils ... read more

May 21, 2015 — Despite a billion years of evolution separating humans from the baker's yeast in their refrigerators, hundreds of genes from an ancestor that the two species have in common live on nearly ... read more

May 21, 2015 — Dogs' special relationship to humans may go back 27,000 to 40,000 years, according to genomic analysis of an ancient Taimyr wolf bone. Earlier genome-based estimates have suggested that the ... read more

May 20, 2015 — Their migration spanned half the globe and their culture was spread across the Pacific and Indian Oceans; but in Madagascar, the ancient Indonesians left behind a ... read more

May 19, 2015 — Researchers determined DNA sequences from the Y chromosomes of 334 men belonging to 17 populations from Europe and the Middle East. The study shows that almost two out of three (64%) modern European ... read more

May 13, 2015 — Archaeologists have found evidence suggesting leprosy may have spread to Britain from Scandinavia. The team examined a 1500 year old male skeleton, excavated at Great Chesterford in Essex, England ... read more

May 12, 2015 — Scientists have successfully replicated the molecular processes that led from dinosaur snouts to the first bird ... read more

May 7, 2015 — Newly evolved genes can rapidly assume control over fundamental functions during early embryonic development. The findings suggest that evolutionary changes to the genetics of fundamental biological ... read more

May 6, 2015 — Biologists have discovered a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types ... read more

May 6, 2015 — A scientist who discovered a new Scottish flower has made an unexpected second finding that provides unique insight into our understanding of evolution. The original find was made even more rare ... read more

May 6, 2015 — Researchers have shown for the first time that cosmic hot spots, such as those near stars, could be excellent environments for the creation of molecular precursors to ... read more

Apr. 29, 2015 — Almost since the time of Melville's epic hunt, scientists have been fascinated by the remarkable attributes of the sperm whale and its kin, the smaller pigmy and dwarf whales. Capable of diving ... read more

DNA Suggests All Early Eskimos Migrated from Alaska's North Slope

Apr. 29, 2015 — Genetic testing of Inupiat people currently living in Alaska's North Slope is helping Northwestern University scientists fill in the blanks on questions about the migration patterns and ... read more
