The 'examine' tool should inform the user of the target's race, so one doesn't have to lose time asking oneself if that's a sized up fat Halfling, a sized down dwarf, or a gnome in thick clothing. Ditto for short caliban in skinny wear vs thick humans. We can't disguise as other races, and as such, we should have a means of confirming what someone's model is.
In an ideal world, the examine tool could allow a canny examiner (maybe with relevant Animal Empathy, Lore, or Spellcraft) to identify if someone is polymorphed or animal shifted, but I imagine this is a lot of work on the back end and that more people will object to it than the above. As it stands, one has to walk the fine line of what is metagaming, and what is logically concluding that dogs / bears / birds / slaad are acting strangely enough to conclude it's a person.
