What point dose the professor make when she mentions squirrels?

2) Mammals have more than one way of regulating their temperture.
3) Smaller animals have more success than larger animals in adapting to
different microclimates.

截文:

P: Well, since cold air sinks, and these spots are shaded, they are usually
much cooler than the surrounding area. And these spots are so important because
many animals rely on microclimates to regulate their body temperature. Hmm, for
instance, there is a species of squirrel, in the Western oart of the United
States that can get really hot when they were out foraging for food. So they
need a way to cool down. So what'd they do? They go back to their own burrow.
Once tehy get there, their body temperature decrease very very quickly. The
trip to the burrow prevents the squirrel from getting too hot.

S: But squirrels are mammals, right?

P: Mammals do have the ability to regulate their body temperature, but not all
can do it to the same degree, or even the same way. Like when you walk outside
on a hot day, you perspire, and your body cools itself down, a classic example
of how mammal regulate its own body temperature. But one challenge that
squirrels face, well many small mammals do is that because of their size
sweating would make them lose too much moisture. They dehydrate. But on the
other hand, their small size allows them to fit into very tiny spaces. So for
small mammals, microclimates can make a big difference. They rely on
microclimates for survival.


我覺得兩個選項都有線索阿= =? 有沒有版有這題也有疑惑的...
