Ida's Anatomy

Explore the anatomical traits you have in common with this 47 million year old primate.

There's something strikingly familiar about Ida's skeleton. That's because, like us, Ida is a primate. She lived around the time that primates split into two major groups. The prosimians are the non-human branch who have survived mainly as modern lemurs. The anthropoids are the other branch - from which humans evolved.

Ida's skeleton has some early anthropoid traits. These foreshadow physical features which later appear in monkeys, apes, and of course, humans. So although Ida was a primitive primate who lived 47 million years ago, her anatomy has remarkable similarities to our own.
