“We now know from sequencing the entire DNA of species and (their genomes) that not only do flies and humans share a large cohort of developmental genes, but mice and humans have virtually identical sets of about 29,000 genes and that chimps and humans are nearly 99% identical at the DNA level.” (Intro, Page 9 & 10)

“An entire complex creature begins with a single cell, the fertilized egg, in a matter of just a day a (fly maggot), a few weeks (a mouse), or several months (our cells), an egg grows into millions, billions, or in the case of humans, perhaps 10 million cells found in the organs, tissues, and parts of the body.” (Page 4-5)

“How are individual forms generated? And how have such diverse forms evolved? These are very old questions in biology... but only very recently have deep answers been discovered, many of them so surprising and profound that they have revolutionized our views on the making of the animal world and our place in it.” (intro, page 3-4)

“The first shots in the Evo Devo revolution revealed that despite their great differences in appearance and physiology, all complex animals--flies and flycatchers, dinosaurs and trilobites, butterflies and zebras and humans--share a common “tool kit” of “master” genes that govern the formation of patterning of their bodies and body parts.” (Intro, page 9)

“The key to answering such questions is to realize that every animal form is the product of two processes - development from an egg and evolution from its ancestors” (Introduction, page 4)

“Differences in form arise from evolutionary changes in where and when genes are used, especially those genes that affect the number, shape, or size of a structure.”

(Introduction, page 11)

Intro, Pg. 8: “The long drought in embryology was eventually broken by a few brilliant geneticists who, while working with the fruit fly, the work-horse of genetics for the past eighty years, devised schemes to find the genes that controlled fly development. The discovery of these genes and their study in the 1980s gave birth to an exciting new vista on development and revealed a logic and order underlying the generation of animal form.”

“Different kinds of biologists were approaching evolution at dramatically different scaled. Paleontology focused on the largest time scales, the fossil record , and the evolution of higher taxa.” pg 6

“The puzzle of how a simple egg gives rise to a complete individual stood as one of the most elusive questions in all of biology” (intro, 6)

“What is beautiful in science is the same thing that is beautiful in Beethoven. There’s a fog of events and then suddenly you see a connection. It expresses a complex of human concerns that goes deeply to you, that connects things that were always in you that were never put together before.”

“The key to answering such questions is to realize that every animal form is the product of two processes - development from an egg and evolution from its ancestors… Simply put, development is the process that transforms an egg into a growing embryo and eventually an adult form. The evolution of form occurs through changes in development.” (Intro, 4)

"The first approach naturalists took to dealing with the great variety of animals was to sort them into groups, such as vertebrates (including fish, amphibians, reptiles, birds, and mammals)”

These dreamers would, based upon the thousands of species that they saw and collected, launch the first revolution in biology. (pg 2)

“Underlying the many visible elements of animal form are remarkable processes, beautiful in their own right in the way that they transform a tiny, single cell into a large, complex, highly organized, and patterned creature, and over time, have forged a kingdom of millions of individual designs” (Intro, 4).
