Question

Humans and mice have similar genomes. In fact, researchers have found thousands of genes that exist in both mice and humans. What can you conclude about the evolutionary relationship between mice and humans? Do you think these genetic similarities explain why mice are important test animals for human medical research?

Answer 1

The high degree of genetic similarity between mice and humans suggests that they share a common ancestor and have evolved from a common lineage. This close evolutionary relationship is likely why mice have been used as model organisms in biomedical research to study human diseases and develop potential treatments. The genetic similarities make it more likely that findings from studies in mice can be applicable to humans, although there are also important differences that must be taken into consideration. Overall, the genetic similarities between mice and humans make them valuable tools for understanding human biology and health.
