A comparison of the thylacine’s genome to other marsupials has revealed that the creatures lost genetic diversity long before ...

Genetic-sequencing techniques have uncovered the oldest host-associated microbial DNA ever recorded — inside samples of teeth and bones from woolly and steppe mammoths.
