Select one:

a. speech

b. tool use

c. tool making

d. artistic abilities

Answer 1

Answer: c. tool making

Explanation: The expansion of the brain of the genus Homo was thought to be correlated with tool making as humans needed to develop the exact skills (especially motor skills), memory, and planning abilities required to produce tools (stone tool-making ability). This indicates an increase in behavioral and cognitive complexity associated with the larger sized brains in proffering solutions to new environmental challenges.
