约翰·泰勒·邦纳对一个老问题进行了新的攻击:动物和植物的大小和复杂性是如何逐渐增加的问题。“它是怎么样的,”他问道,“一个鸡蛋变成一个精心制作的成年人?”一个细菌,经过几百万年的进化,是如何进化成大象的呢?“作者认为,我们可以从自然选择的角度来理解这种进展,但为了这样做,我们必须考虑发展的作用-或者更确切地说,生命周期的作用-在进化变化中。邦纳以他的作品《动物文化的进化》(普林斯顿,1980年)的读者所熟悉的生动的写作风格,向对生物学感兴趣的普通读者以及进化生物学各个领域的专家发表讲话。这里使用的方法的新颖之处在于将生物体内部的复杂性(特别是细胞分化)与外部(即生态群落内部)的复杂性进行比较。在这两个层面上,大小问题都与复杂性密切相关。这本书展示了如何理解进化的宏伟历程可以来自结合我们的遗传学,发展,生态学,甚至行为的知识。
John Tyler Bonner makes a new attack on an old problem: the question of how progressive increase in the size and complexity of animals and plants has occurred. "How is it," he inquires, "that an egg turns into an elaborate adult? How is it that a bacterium, given many millions of years, could have evolved into an elephant?" The author argues that we can understand this progression in terms of natural selection, but that in order to do so we must consider the role of development--or more precisely the role of life cycles--in evolutionary change. In a lively writing style that will be familiar to readers of his work The Evolution of Culture in Animals (Princeton, 1980), Bonner addresses a general audience interested in biology, as well as specialists in all areas of evolutionary biology. What is novel in the approach used here is the comparison of complexity inside the organism (especially cell differentiation) with the complexity outside (that is, within an ecological community). Matters of size at both these levels are closely related to complexity. The book shows how an understanding of the grand course of evolution can come from combining our knowledge of genetics, development, ecology, and even behavior.
