    Human ancestors born big brained

    H erectus infants may have been born bigger than previously thought
    The pelvis was reconstructed from ancient bone fragments

    A new Homo erectus fossil suggests that females had large, wide pelvises in order to deliver large-brained babies.

    Being born with a larger brain meant our ancestor became independent far more quickly than modern human infants.

    The new finding, published in Science magazine, conflicts with earlier ideas that suggest they had a tall, thin body shape adapted for running.

    Homo erectus is thought to be the first human-like creature to move out of Africa to colonise the world.
