Expanded: Animal studies are just a start. Human trials might get opposite results.

E.g. The drug Indocid or Indocin is safe for human consumption but kills rats. It's a cheap rat killer.

If rats were tested first, we'd assume they'll kill humans. The reverse applies as well.

Yes, but because you take two decades to reach reproductive maturity, and tend to sue if subjected to a lifetime of confinement in a lab being experimented on, we start with the mouse studies.
