Lieberman 2001E.Pdf
news and views Another face in our family tree Daniel E. Lieberman The evolutionary history of humans is complex and unresolved. It now looks set to be thrown into further confusion by the discovery of another species and genus, dated to 3.5 million years ago. ntil a few years ago, the evolutionary history of our species was thought to be Ureasonably straightforward. Only three diverse groups of hominins — species more closely related to humans than to chim- panzees — were known, namely Australo- pithecus, Paranthropus and Homo, the genus to which humans belong. Of these, Paran- MUSEUMS OF KENYA NATIONAL thropus and Homo were presumed to have evolved between two and three million years ago1,2 from an early species in the genus Australopithecus, most likely A. afarensis, made famous by the fossil Lucy. But lately, confusion has been sown in the human evolutionary tree. The discovery of three new australopithecine species — A. anamensis3, A. garhi 4 and A. bahrelghazali5, in Kenya, Ethiopia and Chad, respectively — showed that genus to be more diverse and Figure 1 Two fossil skulls from early hominin species.

Lake Turkana National Parks عقوملا تامولعم Country: Kenya Inscribed in: 1997 Criteria: (viii) (x) The most saline of Africa's large lakes, Turkana is an outstanding laboratory for the study of plant and animal communities. The three National Parks serve as a stopover for migrant waterfowl and are major breeding grounds for the Nile crocodile, hippopotamus and a variety of venomous snakes. The Koobi Fora deposits, rich in mammalian, molluscan and other fossil remains, have contributed more to the understanding of paleo-environments than any other site on the continent. © UNESCO صخلملا 2017 Conservation Outlook Critical Lake Turkana’s unique qualities as a large lake in a desert environment are under threat as the demands for water for development escalate and the financial capital to build major dams becomes available. Historically, the lake’s level has been subject to natural fluctuations in response to the vicissitudes of climate, with the inflow of water broadly matching the amount lost through evaporation (as the lake basin has no outflow). The lake’s major source of water, Ethiopia’s Omo River is being developed with a series of major hydropower dams and irrigated agricultural schemes, in particular sugar and other crop plantations. -

Diversification of African Tree Frogs (Genus Leptopelis) in the Highlands of Ethiopia

We sequenced 14 nuclear and three mitochondrial genes, and gener- ated thousands of SNPs from ddRAD sequencing to study the evolutionary relationships of Ethiopian Leptopelis. The five species of highland Leptopelis form a monophyletic group, which diversified during the late Miocene and Pliocene. We found strong population structure in the fossorial species L. gramineus, with levels of genetic differentiation between populations similar to those found between arbo- real species. This could indicate that L. gramineus is a complex of cryptic species. We propose that after the original colonization of the Ethiopian highlands by the ancestor of the L. -

The Turkana Depression consists of several Oligocene to Pliocene North-South oriented half- grabens that connect the Ethiopian and Kenyan rift valleys within the eastern branch of the Cenozoic East African Rift System. In the northern portion of the Turkana Depression, exposed on the west side of modern Lake Turkana, is the Nachukui Formation that consists of a > 700 m pile of fluvial-deltaic-lacustrine sediments deposited between 4.2 and 0.7 Ma. The Nachukui Fm is a world- class fossil-bearing succession into which more than 500 hominin fossils were discovered, including major discoveries for the understanding of Human evolution and more than 100 archaeological sites. Most significant discoveries include Australopithecus anamensis, Kenyanthropus platyops,Paranthropus aethiopicus,Paranthropus boisei and specimens of Homo (i.e., H. rudolfensis and H. erectus) and early members of H. sapiens, as well as the earliest evidence of Acheulean stone tool technology and, more recently, the most primitive Lomekwian stone tool technology. -

Our first stop is on the summit of Silale crater, and then we drop down into the Suguta Valley. The landscape is constantly changing - desolate salt plains, lava flows and crocodile pools, through the colourful ‘painted’ and ‘hoodoo’ valleys. We touch down on the sand dunes, fly over the soda lake of Logipi where flocks of flamingo paint the shores pink, and we finally arrive at the fresh waters of Lake Turkana. Besides Nabuyatom Crater we touch down for refreshments. We return following the most scenic route, over the Ndotos and Mathews - a dominant mountain range that rises from the arid plains, with mist forests and ancient cycads on its summit.

Kariandusi an Online Guide to the Museum Kariandusi – a Site in Kenya’S Rift Valley
Kariandusi an online guide to the Museum Kariandusi – a site in Kenya’s Rift Valley Kariandusi was one of the first early archaeological sites to be discovered in East Africa, which is now famed as a cradle of human origins. The sites lie on the eastern side of the Gregory Rift Valley, about 120 km NNW of Nairobi, and about 2 km to the east side of Lake Elmenteita. From Kariandusi you can look across the width of the Rift Valley. The Nakuru- Elmenteita basin is flanked by Menengai volcano on the north, and by the volcanic pile of Mount Eburru on the south – visible from Kariandusi. Much geological evidence shows that at times in the past this basin has been occupied by large lakes, sometimes reaching levels hundreds of metres higher than the present Lakes Nakuru and Elmenteita. Lying at a height of about 1880 m (nearly 6200 ft, the Kariandusi sites would have been near the side of one of these former lakes. Impressive scarps of the Rift wall rise less than one kilometre behind the sites, continuing as the Bahati Escarpment to the north, and the Gilgil Escarpment further south. The scarps behind rise to 2250 m (7400 ft) less than 3 km from the sites. The site area from the North with the Rift Valley scarp In the background Close to the sites the scarps of the Rift Valley wall are dissected by the valley of the Kariandusi River, which has a relatively short course, fed partly by waters from Coles' Hot Springs, only 2 km from the sites.
