The correct answer is skeletal development resulting in the movement of amphibians onto land and possibly evolved from lobe-finned fishes.
The initial lobe-finned fishes are bony fish with lobed, fleshy, paired fins that are connected with the body by a solitary bone. The fins of the lobe-finned fishes vary from those of all other fish in that each is borne on a lobe like, fleshy, scaly stalk protruding from the body.
This skeletal development will show that the species first developed in water and then gradually move onto the land and ultimately developed as species of land.

Answer:
The increase in cranial or cerebral capacity inherited from the primate ancestors is the characteristic that allows the creation and use of tools.
Explanation:
The evolution of the human brain allows the creation of more complex tools.
Homo habilis was the first hominid to make tools. its size was similar to the australopithecus but its brain was twice with a cranial capacity of 650 cc. These tools were made of stone and were used by striking against each other.
