Mice are often used in scientific research because they share many genetic and physical traits with humans. However, since mice and humans evolved in different environments, they have distinct differences. While both species have certain shared biological processes, their reactions to experiments can vary significantly. Mice are great for studying shared biological traits and understanding how different species develop from common genes. But when it comes to mimicking human diseases, mice might not always be the best models since the connections between genes and diseases can vary between humans and mice. So, while mice are helpful in research, it's essential to consider both their similarities and differences with humans. | [[File:Black 6 mouse eating.jpg|thumb|C57BL/6, female, 22 weeks old]] | ||
