The novel delves into the concept of blood relationships through the lens of genetic engineering. The character of Dr. Henry Wu, the chief geneticist at InGen, is obsessed with creating a new breed of dinosaurs. Wu's focus on genetic manipulation raises questions about the nature of parenthood and the consequences of playing God. The park's creator, John Hammond, also grapples with the idea of paternity, as he sees the park as his legacy and a testament to his vision.
