An interesting tidbit about our more recent past. Love Liza -- [log in to unmask] (Liza May) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fossilized pelvises of humans and our hominid relatives can help teach scientists how our brain evolved and how we learned to walk on two legs, but they're extremely rare. Scientists found a 200,000-year-old fossilized pelvis from Spain. The bone belonged to a hominid that had wide hips and could give birth to babies with large heads. Thus, these early humans, like lower primates, gave birth to babies with a more fully developed brain. This means that a peculiar human trait - a brain that is born immature and develops after birth - evolved later. Arsuaga, J.-L., Lorenzo, C., Carretero, J.M. et al. 1999.
