Both in biological and behavioral terms, our species has experienced a spectacular evolution. The answer to this great change has found its clues in a series of objects found in the middle of the african desert.
Kenya has long been known as “the cradle of humanity”Since it was the place where a series of fossils were found that could be part of the first remains of human life. Following these ancestors, various species evolved millions of years ago. Much research has focused on human origin, but if so, if it is true that Africa was the place of origin, the reason that led them to abandon it to proceed to colonize the rest of the world. There is still very little information about what really happened, how the species evolved creating different population groups and languages.
Dr. Marta Mirazón Lahr, involved in the Africa project and recently awarded five years of funding by the European Research Council, aims to find the places that recover the evidence of this town through their stone tools, animals, ornaments and even the fossils of the people themselves. Mirazon Lahr has already conducted three other expeditions in 2009, 2010 and 2011 focusing on the Turkana sites, the Nakuru basins and Naivasha of the Rift Valley in Kenya.
10,000 years ago the landscape, very different, was humid and was populated by gazelles, hippos and lions and although the water is a thing of the past its beaches are still there. A great variety of objects have been found in them, such as shells and harpoons used for fishing, some buried and others uncovered thanks to the wind.
The oldest fossil belonging to a modern human is from ago 200,000 years and comes from the Lake Turkana Basin so in this area they are trying to find the origins of homo sapiens. Around 700 objects have been found on the beach, one of the largest collections in Africa.
One of the most important features is the use of animal bones to make tools, a method that had not been used in previous populations, and that provide a great clue about technological and behavioral changes.
The people who lived around the lake used differently the stones in regards to their role as tools. Instead of producing one or two large scales, the first modern humans produced a large number of these in order to create composite tools and thus show their adaptation to different conditions.
Geography and climate played a fundamental role in the origin and diversification of modern humans, thus, the times when the lakes were abundant were periods in which the vegetation grew and the town prospered.
East africa It had a unique geography made up of lake basins, plains, and mountains that provided alternative niches. By comparing the fossil records over time in the different basins, it is expected to establish a spatial and temporal pattern that has been taking place in the last 200,000 years.
Thanks to the combination of genetic, fossil, archaeological and paleoclimatic information, various points of view will be formed that will make look at the evolution from different angles.

I was born in Madrid on August 27, 1988 and since then I started a work of which there is no example. Fascinated by both numbers and letters and a lover of the unknown, that is why I am a future graduate in Economics and Journalism, interested in understanding life and the forces that have shaped it. Everything is easier, more useful and more exciting if, with a look at our past, we can improve our future and for that… History.
