The Quaternary Period is the most recent of the three
periods of the Cenozoic Era. The Quaternary Period is characterized by a continous
alternation between calids and cold periods. The associated environmental
changes with these cycles of climatic changes have been thoroughly studied by
the using of chemical, geological and biological proxies. These works have
tried explaining and describing the differents scenarios of the evolution and
migrations of the ancient human's populations, and its impact over ecosystems,
especially with the extinction of the megafauna from news colonized by our
ancestors. Nevertheless, there are many questions about these topics... and, in
this, the new generations of palaeontologist have a lot to say!
