In the meantime, one is obliged to consider the workings of the three in the classical manner, one at a time; remembering that, eventually, the bits will patch together to yield a much more beautiful story.

Introduction,dict simply from a knowledge of its cell biology. Why was the basic molluscan design extended in the particular ways that we find in an octopus? Chemistry cannot tell us. But perhaps behaviour can. This is why this book, unfettered by the need to be comparative, includes much about behaviour, and ra
