Animal Quote by Stephen Jay Gould
“We can now determine, easily and relatively cheaply, the detailed chemical architecture of genes ; and we can trace the products of these genes ( enzymes and proteins ) as they influence the course of embryology . In so doing we have made the astounding discovery that all complex animal phyla - arthropods and vertebrates in particular - have retained, despite their half-billion years of evolutionary independence, an extensive set of common genetic blueprints for building bodies.”

Source Speech: Public lecture on evolutionary genetics, 1990s
The quote highlights that despite vast evolutionary time, animal groups share many core genes that shape development and biology.
In simple terms: Animals share many core genes despite long evolution.
