I'm not entirely sure about this. How does one differentiate between adaptations for cruising flight, and adaptations for gliding?

I would expect a trend toward higher aspect ratio for a glider.

How does one detect a trend, or lack thereof, in what amounts to a single data point (i.e. Archaeopteryx)?
