This work examines rules, system properties and mechanisms underlying developmental gene regulation in a broad range of organisms. It covers the thoughts and theories, experimental inventions, strategies and successes of recent investigations into developmental processes in organisms ranging from yeast and fungi to higher eucaryotes. Some of the specific topics covered calcium, cell cycle control, the role of protein kinase
Eric Harris Davidson was an American developmental biologist at the California Institute of Technology. Davidson was best known for his pioneering work on the role of gene regulation in evolution, on embryonic specification and for spearheading the effort to sequence the genome of the purple sea urchin, Strongylocentrotus purpuratus. He devoted a large part of his professional career to developing an understanding of embryogenesis at the genetic level. He wrote many academic works describing his work, including a textbook on early animal development.
