  2. Our Bigger Brains Came With a Downside: Faster Aging

    A study comparing chimpanzee and human brains suggests that the regions that grew the most during human evolution are the most susceptible to aging.

    The darker green regions of the brain show the parts that have expanded the most during human evolution. A new study shows that they are the same sections that shrink the most during aging.

  5. How Did Roses Get Their Thorns?

    The “prickles,” as botanists call them, evolved in roses and other plants thanks to a single gene, a new study found.

     By Carl Zimmer

    Prickles likely arose in many plants as a defense against animals that would devour them, but prickles can serve other purposes, such as for hooking onto surfaces while climbing or attaching seeds onto the fur of passing animals.
