Today, on a Moment of Science, how humans are like rats. One argument against scientific experiments involving animals is that physiological differences between humans and other species is so great that an animalâs response to a certain procedure or medication actually tells us nothing about the likely human response.eâre both warm blooded, and rats eat everything we doâ¦ and live where we live. More importantly, rats and humans often suffer from the same diseases. Thatâs because humans and rats have the same basic physiology, similar organs, and similar body plans.

And yet the similarities may give us some knowledge of the roots of some human behaviors.et, clearly there are differences in behavior among different species of primates-especially humans.
