1 study

  1. Experimental evolution extends lifespan in S. beetle (compared with populations evolved under regimes favoring a short life) (near doubling of lifespan).

    “Replicated populations evolved under regimes favoring either a short or long life, resulting in a near doubling of lifespan.”

  1. Selection for late reproduction increases germline maintenance in S. beetle.

DNA copy differences tied to lifespan in seed beetles

After more than 200 generations, populations selected for long life showed a near doubling of lifespan compared with those selected for short life.After more than 200 generations, populations selected for long life showed a near doubling of lifespan compared with those selected for short life.
