Battle Xtra:

Come, now, if you will, on a speculative excursion into prehistory. Assume the era in which the species sapiens emerged from the genus Homo . . . hasten across the millenniums for which present information depends for the most part on conjecture and interpretation to the era of the first inscribed records, from which some facts may be gleaned. – P. E. Klopsteg – Science, December 30, 1960, p. 1914

Prehistory4 datings is just educated guessing, bear that in mind.

My intention here is not to show an exhaustive history of everything but only a history of the things I like…
