鸟类和哺乳动物的哪些主要特点决定了他们是进化最成功的脊椎动物？

好的~~
鸟类和哺乳类共同的优点：
体温恒定（至少大部分是），不至于因外界气温影响新陈代谢速率
都有育幼行为，后代成活率比爬行类祖先或者现存的“远亲”们都要高很多。
对比爬行类，智商都要高很多，以及与此相伴的复杂行为，学习能力。甚至是“社会性”的行为。（纵观现全生物，怕也只有部分昆虫能做到这样。单论个体智商的话，部分软体动物【譬如章鱼所在的蛸类】也不错。但是非脊椎动物的这2位神经传导效率均差于鸟和兽）
心室分隔，都拥有4个心房心室，血氧供应能力增强了不少，这就能供应更多的养分给肌肉，运动能力就能强不少
皮脂腺，哺乳动物还有汗腺，均解决了不少代谢问题。
听觉，鸟类的视觉，哺乳动物还有味觉，均比爬行动物进步很多。
与此同时。二者也有不同的优势。
鸟类羽翼飞翔，比起特化膜结构飞翔的前辈（翼龙）优势很大。【当然会飞这件事，昆虫尤其是鳞翅目做的也很不错，然而昆虫在呼吸问题上完败。】
鸟类排尿酸，相对更适干旱环境。
高等灵长类脑部出现了新皮质，这使得智商很快更进一步发展。
高等哺乳动物出现胎生，并在育幼问题上进一步提供投入。后代成长更有保障。
上述相同和不同的特点，决定了鸟和哺乳动物是迄今进化最成功的群体。
鸟类和哺乳动物都有很明显的脊椎。并且其实都很有力气。证明了他们是进化最成功的脊椎动物。
种类和哺乳动物哪些主要特点决定了他们是进化最成功的脊椎动物。当然是人类了。
鸟类和哺乳动物物的主要特点决定了他们的世纪花城。公的。
