Research on animal intelligence always makes me wonder just how smart
humans are. 1 the fruit-fly experiments described in Carl Zimmer’s piece in the
Science Times on Tuesday. Fruit flies who were taught to be smarter than the
average fruit fly 2 to live shorter lives. This suggests that 3 bulbs burn
longer, that there is an 4 innot being too terrifically bright.
Intelligence, it 5 out, is a high-priced option. It takes more upkeep,
burns more fuel and is slow 6 the starting line because it depends on learning —
a gradual 7 — instead of instinct. Plenty of other species are able to learn,
and one of the things they’ve apparently learned is when to 8 .
Is there an adaptive value to 9 intelligence? That’s the question behind
this new research. I like it. Instead of casting a wistful glance 10 at all the
species we’ve left in the dust I.Q.-wise, it implicitly asks what the real 11 of
our own intelligence might be. This is 12 the mind of every animal I’ve ever
met.
Research on animal intelligence also makes me wonder what experiments
animals would13 on humans if they had the chance. Every cat with an owner, 14 ,
is running a small-scale study in operant conditioning. we believe that 15
animals ran the labs, they would test us to 16 the limits of our patience, our
faithfulness, our memory for terrain. They would try to decide what intelligence
in humans is really 17 , not merely how much of it there is. 18 , they would
hope to study a 19 question: Are humans actually aware of the world they live
in? 20 the results are inconclusive.
