[One of my friends who read a lot of science literature, claimed that even the act of eating meat, might actually put foreign DNA into you. But I'm not fully sure I trust that statement. But DNA does move between animal species. This is part of the weirdness of history and evolution and how we change. Jan]

The discovery of a gene shared by two unrelated species of fish is the latest evidence that horizontal gene transfers occur surprisingly often in vertebrates.

Smelt can survive in icy temperatures because their cold adaptations include an antifreezing protein. New work reveals that smelt obtained the gene for this protein through a direct transfer from another cold water fish, the Atlantic herring.
