A person who studies the past via the evaluation of artifacts, ecofacts, and geofacts. Archaeologists do NOT study dinosaur bones. Archaeologists DO have to navigate through a maze of red tape in order to study said items due to the fact that political correctness and all around silliness have created ridiculous laws that impede scientific study so that peoples feelings do not get hurt.
Archaeologist: "wow I just found a site that has 20,000 yr old human remains, these human remains and all the artifacts found with him could tell us how and when humans came to north america, this could be the most important find in the last century"
Random Government/Tribal official: that is too bad, because even though these remains are 20,000 years old I still believe they could be a native american ancestor and therefore I am going to prevent you from studying anything at this site so I can make sure that the government pays to just rebury everything. sorry for your bad luck but my feelings come before breakthrough studies beneficial to all humans"
