According to an archaeologist from the University of York, England, this partly explains the speed at which we have spread around the globe. The speed at which humans spread has changed significantly since 100,000 many years ago. This was partly due to people leaving town to escape from old friends who felt betrayed or let down. Penny Spikins is a researcher at the University’s Department of Archaeology. She believes trust betrayals were what caused the rapid spread of human species all over the globe. The ancient human race was slow, and was mainly controlled by changes in the environment or increased population. After that, the human population grew rapidly across large environmental barriers and spread quickly. After 100,000BP, the dispersal patterns of human populations changed. Image: Openquaternary.com. Dr. Spikins claims that these changes can be linked to emotional changes within the human family. Open Quaternary journal author Dr. Spikins argues that ecological and population changes are not sufficient explanations for how humans have moved to new areas, which began around 100,000 year ago. There was a dark side to our nature. She thinks that when commitments became more important for survival and humans became increasingly driven to punish and find those who cheat, this dark side also emerged. Moral conflicts based on a feeling of betrayal or broken trust were more prevalent in early human history, which encouraged them to distance themselves from those who they considered their enemies. According to Dr. Spikins, the deep emotional bonds that held people together in times of crisis had an even darker side. Modern humans feel these same profound emotions. People who were betrayed by their former friends drove them (and others) to the other side of the city. Our dark side is something that other animals do not have. As social media grew, it was easier to locate distant allies to establish new colonies. Meanwhile, more effective hunting technology made it possible to identify grudge-prone individuals. Human emotions were responsible for repelling occupied spaces – something that is not found in any other animal. The distribution of early hominins was limited to grasslands and open woodland. Homo Erectus’s expansion from Africa to Asia 1.6 million years ago seems to be due to the desire to find larger grasslands. Neanderthals, on the other hand, lived in colder and more arid areas of Europe. The archaic species were slow to adapt to new settlement opportunities and often prevented from settling by environmental and climatic barriers. Things started changing 100,000 many years ago. The dispersal of human populations into remote, unhospitable, and potentially dangerous areas was much more frequent than movements within occupied regions. Biogeographical barriers did not hinder modern humans’ ability to spread. People moved to cold areas of Northern Europe and crossed important deltas like the Ganges and Indus. They also traversed tundra and deserts. To reach Australia and the Pacific Islands, they even traveled long distances on sea. According to the author, betrayals of trust that resulted from moral conflicts were an important reason for their dispersion into seemingly inhospitable environment. A desire to avoid any physical harm from angry or disgruntled former friends and associates was a powerful motivation. Any offenders or their friends within a social circle would feel the need to “get out of town” – get out of danger’s way. Dr. Spikins stated that “Active colonisations in and through dangerous terrain are hard to explain using immediate practical choices. They are easier to understand when there is a rise in the strong motivations that harm other people even at their own cost, which many emotional commitments bring. Open Quaternary. 25 November, 2015.

The spread of deceitful and treacherous humans was rapid
