A Search for Sick Animals - by Trevor Klee - Asimov Press
A 2020 study suggests that monkeys can develop Parkinson’s, just like humans. Why haven't the findings been duplicated, and what will it take to find more “natural” animal models?
Animal models that suffer from the same diseases as humans are perhaps our most valuable resources for studying those conditions. Whether researching cancer in mice, tuberculosis in guinea pigs, or osteoarthritis in horses, scientists use such animals as accelerated case studies. Animals develop diseases more quickly than humans do. They can also be tracked continuously throughout the course of a disease and (unwittingly) serve as test subjects for risky, experimental treatments. But as useful as these models are, not every condition we hope to study occurs in animals.1 Humans are unique,…
