The speckled egg in this hypnotic gif is demonstrating an amazing evolutionary advancement. It’s a strangely pointy egg and it belongs to a Common Murre or Guillemot, a seabird that congregates in large colonies on rocky cliff shores and does not make nests. Instead the birds lay their eggs directly on bare rock ledges. And that’s one of the reasons their eggs have evolved such an unusual shape - so that when they roll, instead of rolling away from their parents and into the sea, they roll in a tight little circle. It’s further proof that nature is awesome.
