 List 4 traits in the Theropoda* lineage that are primitive to Avialae and that contribute to flight in Aves. In your answer, number each of the four traits. The traits can (and probably should) be from different clades within Theropoda. • State the clade or genus each trait appeared in, and whether it was exapted for flight. • You may include up to one figure per trait (properly credited) if useful. • The desсrіption of each trait should be no less than three sentences long, and no more than 1/2 page long (11-12 pt, single-spaced, 1-inch margins), excluding figures. Each trait contributes up to 20 points, as follows: if the trait was derived in the named member of Theropoda and primitive to Avialae, 6 points; if the trait contributed to flight, 6 points; mostly correct how it was adaptive or exaptive for flight, 6 points; and fully correct and well-explained, and any appropriate citations or figure credits done correctly (MLA citation style for references), 2 points. The final 20 points may be awarded as follows: on time
