Turn back the molecular clock, say Argentina's plant fossils

Orangutans harbor ancient primate Alu

Alu elements infiltrated the ancestral primate genome about 65 million years ago. Once gained an Alu element is rarely lost so comparison of Alu between species can be used to map primate evolution and diversity. New research ...
