vCushitic pastoralists formerly spread down
through Central
Africa, at least as far as Zambia/Northern Zimbabwe, probably intermixed with
hunter-gatherers
vThey would have herded fat-tailed sheep and
longhorn taurine
cattle and known how to make pottery
vKhwe speakers would have spread at least to
the borders
of Tanzania, with click speakers possibly right up to Somalia
vSome time about 2000 years ago these two
groups encountered
one another and the pottery skills and livestock breeds were passed between them
along with associated
material culture such as mat huts, sandals and butter-making equipment.
vA diverse pastoral culture would have existed
in this intermediate
zone, observed by San hunter-gatherers who both traded with the herders and painted
their animals.
