    Indian scholar questions Africa-origin theory

    By Staff Reporter

    An Indian scholar and explorer has punched holes in the theory that man originated from the Olduvai Gorge in northern Tanzania and from there spread out to colonise the world.

    Akhil Bakshi who led a multi-disciplinary Gondwanaland Expedition from the Indian Himalaya to Cape Agulhus, the southernmost tip of Africa, has questioned early theories with regard to the cradle of mankind, according to last week’s communiqué to the media.

    The 25,200km expedition comprising geologists, botanist, zoologist, anthropologist and medical doctor, traversed several areas of great importance in the evolution of life on earth. In May 2006, the expedition drove across Tanzania - entering from Isabania border with Kenya, traversing Serengeti to Ngorongoro Crater and from there to Singida and out into Malawi.

    In his paper "Continental Drift and Concurrent Evolution of Human Species – A Critique of the African-origin Theory", Bakshi hypothesises that different races of humans, like many plant and animal species, evolved independently in various parts of the planet.
    Presenting the existence of life on earth when Pangea broke up into Laurasia and Gondwanaland, Bakshi asks if from these life forms Homo erectus could have evolved in Africa, over millions of years, why then, from the same life forms, could he not also have evolved on other continents that had a similar ecosystem and ancestral conditions?

    According to him, the landmasses of Australia, India, and South America –once attached to Africa as Gondwanaland – originally had a Negroid population that had evolved independently. These were later decimated and marginalized by the Caucasian and Mongoloid races migrating from the north. Some inter-mixed.

    Outside Africa, the remnants of the original Negroid population are the Aborigines in Australia-Papua New Guinea, Aeta in Phillipines, Veddas in Sri Lanka and the Great Andamanese tribals in India. They
    Stereotype of prehistoric people
    developed similar Negroid features because their evolution was rooted in the same ancestral background of Gondwanaland. This was original, indigenous population – and not people who migrated from Africa over deserts and oceans.

    The Olduvai Gorge or Oldupai Gorge is commonly referred to as "The Cradle of Mankind." It is a steep-sided ravine in the Great Rift Valley, which stretches along eastern Africa. Olduvai is in the eastern Serengeti Plains in northern Tanzania and is about 30 miles (48 km) long. The gorge is named after the Maasai word for the wild sisal plant Sansevieria ehrenbergii, commonly called Oldupaai.

    It is one of the most important prehistoric sites in the world and has

    Studying the origin of man been instrumental in furthering understanding of early human evolution.
    Excavation work at the gorge was pioneered by Louis and Mary Leakey in the 1950s and continued into the twenty first century by Professor Fidelis Masao of the Open University of Tanzania supported by Earthwatch; there have also been teams from Rutgers University. Millions of years ago, the site was that of a large lake, the shores of which were covered with successive deposits of volcanic ash. Around 500,000 years ago seismic activity diverted a nearby stream which began to cut down into the sediments, revealing seven main layers in the walls of the gorge.

    The earliest archaeological deposit, known as Bed I, according to internet sources, has produced evidence of campsites and living floors along with stone tools made of flakes from local basalt and quartz. Since this is the site where these kinds of tools were first discovered, these tools are called Oldowan. It is now thought that the Oldowan toolmaking tradition started about 2.6 million years ago. Bones from this layer are not of modern humans but primitive hominid forms of Paranthropus boisei and the first discovered specimens of Homo habilis.

    The Olduvai Gorge bears the distinction of having the oldest known evidence of Elephant consumption, attributed to Homo ergaster around 1.8 million years ago.

    Above this, in Bed II, pebble tools begin to be replaced by more sophisticated handaxes of the Acheulean industry and made by Homo ergaster. This layer dates to around 1.5 million years ago.

    This is not provable and it is going as far as to be a mere conspiracy

    As time passes,evidence for the african origin of humanity, piles up to the extent that now,no serious scholar believes the opposite.

    Modern genetics studies have shown that africans (especially east africans) i.e tanzanians have the most diverse DNA, on top of the fact that the oldest skulls have been found in africa,indians, europeans have a subset of african genes and not vise versa.

    The east african is the big daddy!
