Human mobility is vital for genetic diversity and adaptation from "summary" of The Next Great Migration by Sonia Shah
Human mobility has played a crucial role in shaping genetic diversity and facilitating adaptation among human populations throughout history. When people move from one place to another, they bring with them a unique set of genetic traits that can interact with the genetic makeup of the local population. This mixing of genetic material leads to increased diversity within the population, which in turn enhances its ability to adapt to changing environmental conditions. Genetic diversity is essential for a population's survival and resilience in the face of challenges such as disease outbreaks, climate change, or other environmental stressors. The more genetically diverse a population is, the greater the likelihood that some individuals will possess traits that enable them to survive and reproduce in changing conditions. Human mobility has been a driving force behind the spread of beneficial genetic traits across different populations. As people migrate and intermingle with others, they introduce new variations into the gene pool, increasing the overall genetic diversity of the population. This process of gene flow helps to create a dynamic and adaptable genetic landscape that can respond to selective pressures over time. In addition to promoting genetic diversity, human mobility also plays a crucial role in facilitating adaptation to new environments. When people move to a different location with different environmental conditions, they may encounter new selection pressures that favor certain genetic traits over others. Through natural selection, individuals with advantageous traits are more likely to survive and reproduce, passing on their genes to future generations.- Human mobility has been a driving force behind the continuous reshaping of human genetic diversity and adaptation. By moving and mixing with different populations, humans have created a rich tapestry of genetic variation that has enabled our species to thrive in diverse environments around the world. This ongoing process of genetic exchange and adaptation is a testament to the resilience and ingenuity of human populations throughout history.
