The prefix eco- mean "out", and the prefix endo- mean "in." what do these prefixes tell you about exothermic and endothermic reactions?

Exothermic reactions occur outside of the object, while endothermic occur on the inside.

Ihaven't done that yet, so no idea,but this is not the right place to ask

Many archeologists and anthropologists disagree with dr. thorne's view.  thorne strongly believes that what many calls "homo erectus"  was in fact  homo sapiens,  and that they migrated out of africa almost 2 million years ago and dispersed throughout europe and asia. that's way different  from what scientists have always believed about the evolution of the species.
