Suppose you are excavating a site that is dated to 3 million years BP. You find a set of footprints that show a foot with a "divergent" big toe (that can be used to grasp things). What can you conclude

The conclusion is that the footprints are Australopithecus afarensis footprints; they are considered as early human.

Explanation:

Australopithecus afarensis are comsidered to be more related to Genus Homo; a classification that includes present day man, Homo Sapiens.

They have characteristics of both ape and human, which includes a flat nose and song protective lower jaw, while having smaller braincase of about one third of that homo sapiens.

It also said that Australopithecus has a slender body, long but strong arm, plus the fingers that are curved like that of human. They are extinct hominin.
