When ancient fossil DNA isn’t available, ancient glycans may help trace human evolution

Researchers have 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 sets the stage for unprecedented explorations of human origins and diet.
