#The missing link human evolution solution free#
As a result, they opted to adapt to a new environment out of the forests, and their ability to walk on two legs left their hands free to carry food and take care of their offspring, which eventually enabled them to survive in the harsh environment of the savannah.įound in the Djurab Desert in northern Chad, Central Africa, Toumai dates back some 6 or 7 million years, making it one of the oldest hominid fossils ever found. These earliest humans of the savannahs picked plants and berries, ate insects or scavenged the leftovers of large predators, although they were so vulnerable that they often became the prey of carnivores, such as lions, themselves.
Accordingly, they climbed down from the trees and began to stand upright on two legs, spending more time on the ground.
However, changes in their living environment, namely, from forests into grasslands due to climate change led to food shortages, leaving them no choice but to adapt to the new savanna environments. The ancestors of Australopithecus dwelled in tropical rainforest trees from which they obtained abundant food. Ultimately, much of the African continent gradually transformed from a tropical rainforest region filled with trees and forests into vast savannahs, in other words, dry grassland with a scattering of trees. This diastrophism was also accompanied by continuous climate change – changing wind conditions, repeated cycles of extremely cold and hot weather, and a decrease in rainfall. The Great Rift Valley that divides the continent into eastern and western Africa is also believed to have formed during this crustal movement, or so-called ‘diastrophism’. The First Humans: The Savannah of East Africa Approximately ten million years ago, Africa experienced frequent and powerful volcanic eruptions and, as a consequence, massive cracks started to form on the Earth’s crust and the continent started to break apart. The moment you enter the Jeongok Prehistory Museum, you will join a several-million-year journey through the history of human evolution, walking alongside our human ancestors.
The past brought us into existence and the future will lead us on an evolutionary journey. However, there is no doubt that human beings have made a great march in terms of human evolution. As a result, even professionals often propose conflicting opinions about the time and location of settlement of a certain species. Archeologists, anthropologists, and paleontologists are continuously striving to solve some very complicated and difficult jigsaw puzzles concerning the human evolutionary process, largely relying on ancient fossils, relics, and DNA analysis results. Collecting such evidence of evolution is an extremely difficult and time-consuming process. The first humans started their great march across the vast land of Africa. Walking upright on two legs is often considered by scientists to be the most fundamental defining trait of human beings. Similar to the ancestors of gorillas, they spent most of their time in the trees, but they were also able to walk on two legs on the ground quite easily. Our earliest ancestors began to evolve in Africa about six or seven million years ago.
