(Newser) – An insight into our human ancestors from an unexpected source and a common trait among mammals make the list:

  • Oldest Human Poop Discovered: Neanderthals who squatted by a campfire in Spain around 50,000 years ago left something that has got today's scientists very excited. What is believed to be the oldest human poop ever discovered has yielded important information about the Neanderthal diet.
  • Mammals Big and Small Pee in 21 Seconds: Ever wonder why it doesn't take elephants an hour to pee? Well someone did. After studying mammals of all walks of life at Zoo Atlanta, scientists discovered that, aside from those that weigh 6.5 pounds or less, it takes the rest of us mammals on average 21 seconds to pee, give or take.

The findings might make their way into human pacemakers.
