Article Title：Archaeology and cognitive evolution
Abstract：
Archaeology can provide two bodies of information relevant to the understanding of the evolution of human cognition - the timing of developments, and the evolutionary context of these developments. The challenge is methodological. Archaeology must document attributes that have direct implications for underlying cognitive mechanisms. One example of such a cognitive archaeology is found in spatial cognition. The archaeological record documents an evolutionary sequence that begins With ape-equivalent spatial abilities 2.5 million years ago and ends With the appearance of modem abilities in the still remote past of 400,000 years ago. The timing of these developments reveals two major episodes in the evolution in spatial ability one, 1.5 million years ago and the other, one million years later. The two episodes of development in spatial cognition had very different evolutionary contexts. The first was associated with the shift to an open country adaptive niche that occurred early in the time range-of Homo erectus. The second was associated With no clear adaptive shift, though it does appear to have coincided With the invasion of more hostile environments and the appearance (if systematic hunting of large mammals. Neither, however, occurred in a context of modem hunting and gathering.
