6 History and Science of Knots

              Homo habilis seems to have made caches of his stone tools, presumably
          for some future use, and also to have carried them over considerable distances
          115, pp. 38, 48]. But there is no way of telling whether they were carried loose
          in the hands or bundled together in some way, which could have implied some
          use of cordage. A more or less circular accumulation of stones at a habitation
          site at a level of Olduvai Gorge dated at nearly 2 million years ago was at one
          time thought to represent a shelter of skin-covered branches held in place by
          the stones, which could have needed some cordage to stabilise it. But further
          examination showed that this was more likely to be a random association of
          rocks and stone tools, and few now believe in the shelter theory [14].
              Thus the material evidence from this period provides little evidence about
          whether Homo habilis had either the cognitive status or the technological
          competence to tie knots, but it cannot be ruled out.

          Homo erectus

          Homo erectus ('upright man') has provided us with numerous skeletal finds
          from the three Old World continents, although some physical anthropologists
          tend to question his presence in Europe. Generally ranging from perhaps 2.0
          to 0.4 million years or so ago, his remains have been found in various parts
          of Africa, in China, Java, and at a few sites in Europe. The period of his
          presence coincides with an increasingly differentiated tool industry, but in the
          later period it is far from certain which of these tools are attributable to Homo
          erectus, and which belong to the emerging archaic Homo sapiens of 500 000 to
          300 000 years ago. The stone tool industry named Acheulian is often attributed
          to Homo erectus, and consisted of large, bifacial tools (called `handaxes' or
          `fist axes'), cleavers, scrapers and a repertoire of flake tools, all hand-held;
          prismatic blade tools appear in the late phases. The Asian and European sites
          of skeletal remains of Homo erectus are strikingly free of handaxes, even at
          localities where over a hundred thousand stone tools were recorded. It has
          been suggested that in Asia, bamboo tools might have replaced stone axes for
          some purposes.
              Acheulian camp sites have been identified over much of Africa, across
          western, central and southern Europe, on the Black Sea, in the Levant and as
          far east as India. In Africa, the Acheulian begins perhaps with the appear-
          ance of Homo erectus, but continues long after his demise, to about 150 000
          years ago. Even early Acheulian tools cannot, always and with certainty, be
          attributed to Homo erectus. Concurrent with much of this period, there are
          various handaxe-free tool industries, and there are no significant differences
          between the apparent methods of subsistence, cognitive development or tech-
          nologies of late Homo erectus and contemporary archaic Homo sapiens pop-
          ulations. Essentially, these hominids began to use fire, erect simple shelters
