What human traits do vampires have?

Answer 1

It depends on which context, and what you would define as human traits:

If you are referring to mythology in that humans become vampires, then they share many traits with humans, as they were originally that species. Such traits as human skeletal structure, musculature, facial features, hair, eyes, ears, the capacity to breath and digest nutrients (although the food source would be different (i.e. blood).

When referring to other species which require blood ingestion (for whatever reason, for example: to postpone coagulation of their own blood), such as vampire bats and various insects, the similarities to humans decreases. Taking into account vampire bats, they do share more human traits as opposed to insects, such as a skeletal and muscular structure and similar organs in which to receive sensory information, as well as beating hearts and a vascular system. However, given their physiology, these traits would only be considered as human traits in the sense that humans have them.
