The system of rift valleys that characterizes the African continent represents a perfect environment to understand the evolution of mankind ; for the important paleoanthropological discoveries in Ethiopia, Kenya, Tanzania, Uganda and Zaire, the African rift valleys are indeed considered the “cradle of mankind”, that is ...
Why is the Great Rift Valley an important physical feature?
The Rift Valley has been a rich source of fossils that allow study of human evolution , especially in an area known as Piedmont. Because the rapidly eroding highlands have filled the valley with sediments, a favourable environment for the preservation of remains has been created.
Why is the Great Rift Valley important to the development of the human species?
Discoveries in human evolution
The Rift Valley in East Africa has been a rich source of hominid fossils that allow the study of human evolution . The rapidly eroding highlands quickly filled the valley with sediments, creating a favorable environment for the preservation of remains.
Why is the Great Rift Valley so critical to the study of human evolution?
The Great Rift Valley is an important area of the world for understanding the origins of human evolution because it is a massive geological feature characterized by active volcanoes and earthquakes over millions of years . ... This discovery helps to illuminate hominin evolution in a unique way.
What is special about the Great Rift Valley in Africa?
The Great Rift Valley is a geographical and geological feature running north to south for around 4,000 miles (6,400 kilometers), from northern Syria to central Mozambique in East Africa. Astronauts say it is the most significant physical detail on the planet that is visible from space.
Which is the longest rift valley in the world?
| World Rift/Valley Length | Earth Great Rift Valley 6,000 km (3,700 mi) | Canadian Arctic Rift System 4,800 km (3,000 mi) | West Antarctic Rift System | Midcontinent Rift System 2,000 km (1,200 mi) |

What are 5 physical features?
Landforms include hills, mountains, plateaus, canyons, and valleys , as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins.
Why is Africa the cradle of humanity?
The Cradle of Humankind is an area in South Africa where many fossils, tools, and other traces of early humans have been found. ... The region is called the Cradle of Humankind because some of the earliest ancestors of modern humans were born there . The oldest evidence dates back three million years or more.
Is Africa the birthplace of humanity?

Why has the Great Rift Valley of Africa been so important to paleoanthropologists?
The Rift Valley in East/Northeast Africa has been an important source of Basal Pleistocene and Pliocene fossils because this geological phenomena has exposed deposits from these time periods for fossil hunters to explore .
What part of Africa did the first human appear?
The earliest humans developed out of australopithecine ancestors after about 3 million years ago, most likely in Eastern Africa , most likely in the area of the Kenyan Rift Valley, where the oldest known stone tools were found.
Where did first human appear?
Humans first evolved in Africa , and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
What country in Africa did humans come from?
sapiens most likely developed in the Horn of Africa between 300,000 and 200,000 years ago. The “recent African origin” model proposes that all modern non-African populations are substantially descended from populations of H. sapiens that left Africa after that time.
Does the Great Rift Valley have volcanoes?
The Great Rift also hosts one of the strangest volcanoes on planet earth.
How does rainfall impact Africa?
Increases in temperature and changes in rainfall patterns also significantly affect population health across Africa. Warmer temperatures and higher rainfall increase habitat suitability for biting insects and the transmission of vector-borne diseases such as dengue fever, malaria and yellow fever.
Is the Great Rift Valley Hot?
Great Rift Valley
The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.
