As I mentioned before, my dinosaur zoology book will be based on a concept known as speculative evolution. Speculative evolution is the practice of theorizing how certain species would evolve under certain circumstances. Even though these animals are fictional in nature, their biology and behavioral traits are based on scientific concepts. These hypothetical creatures provide scholars a chance to provide educated guesses on how the planet’s biosphere would develop under certain conditions. With my dinosaur series, I am depicting how manmade genetically engineered prehistoric lifeforms would adapt to an equally artificial habitat. Above are three videos that talk about the origin and history of the study of speculative evolution.
