THE NARRATIVE OF LIFE'S ORIGINS
Although the Vredefort Dome is deservedly
famed for its geology, there is aspect of the area that has
been little studied - the ancient evolution of life and its
more recent history. This section of the website takes up
the theme, looking at the accumulating scientific evidence
that South Africa, and the Dome in particular, bring to the
story of evolution. There are actually three story-lines to
be developed about life in the area:
-
Archaic
life: the emergence of life itself, recorded in the most
ancient fossilised rocks or stromatolites. Read more
about them
here.
-
Humankind:
the discovery of humanity's origins in the remains of
proto-human skulls and skeletons, as well as diggings
revealing Africa's rich cultural past. Watch this
website for more on these topics.
-
History:
reconstruction of the human record from the "first
people" (the Bushmen) through settlements, wars and
migrations to modern life. A special interest is Dome
Battlefields.
ARCHAIC LIFE
The earliest
life forms of which we have a record around the Dome are
stromatolites - ancient fossilised bacterial structures -
dated between 2.6 and 2.4 billion years ago. This does not
make them the oldest traces of life on Earth, which
may go as far back as 3.9 billion years, but the
stromatolites in this region are significant because they
predate the Vredefort blast. There is a debate about whether
the course of evolution was changed by the blast.
HUMANKIND
The story of
life encompasses several narratives that have anchor points
in this region. Just north of the Vredefort Dome World
Heritage Site (WHS) lies the Cradle of Human Kind, also a
Unesco WHS. The Cradle is where fossils of some of the
earliest human beings have been found in the caves at
Sterkfontein and Drimolen, some 45 km west of Johannesburg.
Much of Cradle site
is on dolomite – a rock type which is slightly soluble in
water – which resulted in the formation of the caves
that trapped the bones of animals and early man. In some 200
caves in the area, paleoarchaeologists have found the
remains of our ancestors and their stone axes and scrapers.
Amazing finds such as “Mrs. Ples” and the lesser-known, but
equally significant “Mr Ples” and “Little Foot” have
led scientists to suggest that humankind first appeared in
this corner of Africa up to 3 million years ago. Fossils of
other creatures include those of extinct animals such as
short-necked giraffe, giant buffalo, giant hyaena and
several species of sabre-toothed cats.
The Vredefort
area has no dolomite caves and hence no fossils of the kind
dug out at the Cradle, but since the areas are closely
adjacent and the landscapes of both would have supported
animal and human life, we can assume that early man
flourished here too.
HISTORY
The region
formed by Johannesburg and Pretoria in the north,
Vereeniging in the east and the Vaal River stretching to
Kimberley in the west has played an important role in South
African history. Agriculturally it is the centre of the
"maize triangle" and its mining wealth is based on the
greatest concentration of gold on earth. Successive
waves of human migration passed across the area for many
centuries before modern tribes and white settlers arrived.
The Vredefort Dome is in the heart of this culturally and
historically rich region. Watch the battlefields and history
sections of the website for pages that are being steadily
added.
