Perhaps some of them could climb trees, but no convincing analysis has demonstrated how Archaeopteryx would have both climbed and flown with its forelimbs.

也许其中一些祖鸟会爬树，但是没有令人信服的分析证明始祖鸟是如何用它的前肢既爬又飞的。

This objection was reasonable when only early theropod clavicles had been discovered, but fossilized theropod clavicles that look just like the wishbone of Archaeopteryx have now been unearthed.
