Ahh but what if the planet had less mass and thus less gravity to allow
birds to acquire larger brains? You could easily come out with an
earth-like planet where flying is more popular than walking.

Does this mean that as we continue to evolve there will be far more
premature born babies because with technology we can allow them to survive
so the skull size can be larger? Eventually we will require technology to
survive as a species if we don't alter our genes or upload.

Wow. Talk about convergence of two entirely different streams of evolution.

Could it be possible somehow to retrieve these maps and find valuable data
on the changing structure of the ocean floor someday?

Ahh but the one fear we know that will occur at the minimum is fear of the
unknown, just as native american indians were afraid of the european's
horses. I'm wondering if we will have the same response to an alien
species. I wonder if we will find them disfigured if they are somewhat like
us and our detectors pickup on a few bodily structures. It's funny how we
are both curious and afraid of the unknown.
