Genomic Recycling: Ancestral Genes Take On New Roles

Weizmann Institute of Science

Dr. Igor Ulitsky has found that ancient genes that lost their ability to make proteins were “recycled,” surviving across millennia – and species – by evolving to produce a type of RNA that regulates major biological processes. His findings could lead to treatments for a number of genetic diseases.

When Ancient Fossil DNA Isn’t Available, Ancient Glycans May Help Trace Human Evolution

University of California San Diego Health

Researchers at University of California San Diego School of Medicine and collaborators discovered a new kind of glycan (sugar chain) that survives even in a 4 million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept study, published September 11 in Proceedings of the National Academy of Sciences, sets the stage for unprecedented explorations of human origins and diet.

Woolly Rhino Neck Ribs Provide Clues About Their Decline and Eventual Extinction

PeerJ

Researchers from the Naturalis Biodiversity Center in Leiden examined woolly rhino and modern rhino neck vertebrae from several European and American museum collections and noticed that the remains of woolly rhinos from the North Sea often possess a ‘cervical’ (neck) rib—in contrast to modern rhinos. The study, published in the open access journal PeerJ today, reports on the incidence of abnormal cervical vertebrae in woolly rhinos. Given the considerable birth defects that are associated with this condition, the researchers argue it is very possible that developmental abnormalities contributed towards the eventual extinction of these late Pleistocene rhinos.

Understanding Caribbean Mammal Extinctions of the Past Spurs Renewed Focus on Conservation

Johns Hopkins Medicine

A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there. The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region.
