Are humans model organisms?
Because we are the model organisms” (1). Indeed, over the past decade, we have deepened our understanding not only of how the genomic blueprint for human biology manifests physical and chemical characteristics (phenotype), but also of how traits can change in response to the environment.
Why do we use models for human diseases?
When animal models are employed in the study of human disease, they are frequently selected because of their similarity to humans in terms of genetics, anatomy, and physiology. Also, animal models are often preferable for experimental disease research because of their unlimited supply and ease of manipulation.
What are the disadvantages of using a model organism?
| Advantage | Disadvantage |
|---|---|
| Easy and cheap to maintain in large quantities, time and cost effective handling | No easy measure of complex behavior |
| Genetic manipulation is fast and inexpensive (3 month, < $ 500 per transgene) | Only basic measures of cognitive decline |

“Unintelligent design.” That is how Cornell evolutionary biologist Paul Sherman refers to the architecture of the human body. If an “intelligent designer” engineered the human body, he points out, air and food would not travel through the same pipes, making us vulnerable to choking.
