Are there physiological traits common to all tool-building species?

+0
−0

Alien and fantasy creatures can be designed in an infinite number of ways. But are there physiological traits that would be common among all tool-developing (technology-building) species?

As an example, I suspect all such species must have some means of manipulating small things. Whether it be fingers and an opposable thumb or well coordinated tentacles or a remarkably manipulatable pair of jaw pincers. Physiologically, the species needs the ability to manipulate things implying fine motor control and gripping power.

I'm not as interested in how the traits are manifest as I am what the basic traits are. Is there a short list of such traits that can guide creature builders?
