Genetically identical fish diverge in behavior as they mature
Original: Groups of genetically identical fish follow different behavioral paths as they mature
New research reports that groups of fish with identical genes develop along different behavioral paths as they grow older. The finding suggests that factors beyond genetics, such as individual experience or environment, shape behavior over an animal's lifetime. The work is drawing attention from biologists interested in how personality-like differences emerge even without genetic variation.
Why now: The study challenges assumptions that genes alone determine behavior, making it notable for biology audiences.
