Does voltage even matter in this case? Isn't amperage the important bit?

But trees encroach on power lines all the time. I can look out my
window and see half a dozen...

Yes, now *that* makes sense. I knew there had to be a reasonable progression
of changes. I hadn't really integrated the idea of the predators evolving
in step with the prey.

That I'd noticed, yes.

That was actually the whole point of the section between the Apes and
Discovery.
There Russians on the Pan-Am flight were asking Floyd about the
possibility of a viral outbreak on the moon-base, because the Americans
had closed their base to all visitors. When he gets to the moon, it's
revealed that the virus was a cover story to hide the fact that they had
found a monolith on the moon.
The monolith then sent a radio transmission (remember the astronauts
holding their ears in pain? the transmission was picked up on their
headsets) to Jupiter. This directly led to the Discovery mission, which
was really supposed to study the Monolith (and HAL was instructed to lie
to the Discovery crew about it).

The Discovery mission predated the discovery of the monolith, though,
which is why they were able to lie about the mission's true intent in
the first place and get away with it. In the book, the signal was sent
to Saturn, later retconned in 2010 etc to Jupiter to match with the
movie. A lot of stuff in the movie, particularly at the end, only makes
sense if you read the book.

Indeed, the monolith sent the radio transmission when sunlight hit it for
the first time after it was buried back in pre-history. (And according to
the book, it was found due to a "magnetic anomoly" which was presumedly the
circulating currents holding the energy for the transmission, altho I don't
remember if that was mentioned in the movie.)

Yes it does. It's voltage that smashes through the insulation and jumps
over air. Current is what heats the wire up (thus possibly melting the
insulation and making it easier for the voltage to jump, but that
demands a high current in too small cable) and kills people.
