这个起源是英国古生物学家瓦尔克提出,但是在之后瓦尔克放弃(abandon)了这个假说(hypothesis),尽管如此,还是有鸟类学家(Ornithologist)支持这个起源。 2. 进化(evolution) 对于进化方面就是鸟类的翅膀(wing)了,有的认为为了飞行(flight)...

In mammals, birds, snakes and many lizards and fish, sex is determined genetically (either male XY heterogamy or female ZW heterogamy), whereas in alligators, and in many reptiles and turtles, the temperature at which eggs are incubated determines sex. Evidently, different sex-determining syste...

Here, we examine the evolution of metabolic allometry in animals by linking microevolutionary processes to macroevolutionary patterns. We show that the genetic correlation between mass and metabolic rate is strong and positive in insects, birds and mammals. We then use these data to simulate the ...
