However, the size, behavior, and biology of these ancient creatures would have presented significant challenges. Additionally, the lack of evidence of such interactions in the fossil record suggests that humans did not have the opportunity to domesticate these animals. **

Dangerous infectious diseases have only existed since humans because they require a host population to survive and spread. Humans live in close proximity to each other, allowing diseases to easily pass from person to person. Prehistoric mammals and dinosaurs did not live in such densely populated communities, so infectious diseases did not have the opportunity to evolve and spread in the same way. Additionally, the evolution of certain diseases may be linked to specific human behaviors and activities, such as agriculture and urbanization, which have only occurred in recent history. **
