Some of the first birdlike creatures to emerge during the age of the dinosaurs probably couldn't get their heavy wings to take them off the ground, and they likely opted for gliding over flying, new research shows. Modern flying birds have a single primary layer of easily separated long feathers covered with short ones — a design that helps them overcome drag when taking flight. A new analysis of the fossils of two of their ancestors shows that the arrangement of feathers for primitive birds was quite different. The birdlike dinosaurs Anchiornis huxley and Archaeopteryx lithographica had dense overlapping layers of wing feathers that were likely difficult to separate, the researchers found. Instead of lifting off from the ground, these creatures probably climbed trees and used their wings to glide from a height, the scientists said. Science news from NBCNews.

These display feathers turned out to be excellent membranes that could have been utilized for aerial locomotion, which only very late in bird evolution became what we consider flapping flight." |

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
