Marine archaeology is the field of future breakthroughs in extending our knowledge of ancient humans - although I don’t know how long it will take to be able to study what is underwater. In glacial times, the oceans were up to 400 feet lower than they are today! So, a lot more land was exposed and people were living in places that are today under the waves. Needless to say, this field is in its infancy. Some American colleges which have established departments in this field are:
Texas A&M
East Carolina University
University of West Florida
UC San Diego
UConn

Groundbreaking research is currently going on in the area of Early America, changing the dates of what we thought to be the earliest human habitation. White Sands, NM is a current focal point on this continent. Universities in YS and UK doing research there are:
University of Arizona
Cornell
Bournemouth University
Another area of interest for early America is Rimrock Draw Rockshelter in Oregon. The leading university researchers there are:
University of Oregon
Perhaps the biggest breakthroughs in changing our understanding of Early America is in the Amazon Rain Forest. Research there is happening internationally. US and UK universities involved there include:
University of Florida
Yale
U Penn
