The late evolutionary biologist Stephen Jay Gould speaks about the lack of perfection in nature as a better signifier of evolution that the perfections.
The highlight starts at the 3:00 minute mark in the clip as Gould goes on to explain that a Pandas thumb is not really a thumb at all, but an evolutionary tinkering of a common bone in the wrist that evolved to suit the needs of a former predator that was never intended to eat bamboo all day.
Gould is an entertaining speaker and his depth of knowledge is impossible to ignore. Science, and truly the world, lost a great communicator when he passed away.
