Many mainstream medias reported about the finding of the oldest human ancestor from Ethiopia, Africa recently.

We already knew that the 3.2 million years old Lucy was believed to be our oldest ancestor. The scientific name of Lucy is Australopithecus afarensis.

Lucy is different with ape (ancient ape) in terms of:

- start to walk on two legs

- brain

- body size

- strong jaws

The similarity that Lucy’s face is look like apes, and previously live on the trees. Even though Lucy able to walk then, but they still use their hands to hang on the trees.

Skull of the oldest human ancestor

Now, scientists found the oldest human ancestor. 3.8 million years old, Australopithecus anamensis who is older than previous discovered, Lucy.

With new finding, scientists have two hypotheses:

1. Australopithecus anamensis was Lucy’s parents. Then, Lucy had evolved to be an ancestor of Australopithecus hominins. This evolutionary line led to Homo sapiens, modern human, our selves.

2. Australopithecus anamensis had directed evolutionary line to the ancestor of Australopithecus hominins, then Homo sapiens, modern man. Lucy was not involve in this evolution process.

To find out which one is true, scientists needed to assemble reliable data of specimen from:

- different time periods

- different geographical locations

- different evolutionary trajectory.

Hope, we could settle doubt soon and understand more of our ancestors, include the way they evolved to become modern human.
