Greetings !
Intresting, none of the above "answers"
seem to actually adress the question...

Because we want to know the reason for stuff.
Stuff starts from the most basic things and
extends - in our highly evolved minds to
many abstract stuff.
What is the original reason for us to want to
know the reason for stuff ?
By knowing the reason for stuff we can control,
predict and understand the Universe. A reason
or cause is something that is always present if
we have (and we do

) time.
The Universe is guided by the laws of physics.
The most primitive life-forms and objects are
guided by the laws of Physics and Chemistry.
The more complex life-forms are guided by the laws
of Physics, Chemistry and Biology.
What is Biology ?
It is a science that explains the behaviour
of complex systems of particles. These systems
formed as a result of a certain balance of
Physical and Chemical laws that was achieved.
Why would these complex systems want to ask the
question Why ?
Simply because being part of nature they must
follow the laws of Physics. A basic system seeks
to reach an equalibrium. Complex systems do that
too. For the latter, however, it is expressed in
a seemingly different way - we strive towards
our equalibrium by what we perceive as our
"actions" dictated by no other than our
minds - a result of the action of our minds.

what drives our curiosity, and why don't
animals have the same drive?
Of course they do. The above explains what
drives this curiosity.
Why are we more curious ?
Simple - we're more complex.
