“Uncovering the Surprising Ways Humans Adapted to the Last Ice Age”

A recent study has challenged longstanding theories about human adaptation during the last ice age, suggesting that humans, wolves, and bears may have adapted in similar ways. The study, led by Oxala García-Rodríguez at Bournemouth University, used genetic data to show that at least some humans stayed in central Europe during the last ice age, contrary to previous beliefs that they retreated to southern Europe.

The research focused on the genetic history of 23 common mammals in Europe, including humans, rodents, insectivores, ungulates, and carnivores. By analyzing the genetic diversity of these mammals across Europe, the study identified areas of high genetic variation, known as refugia, where species retreated to survive during unfavorable environmental conditions.

The study revealed different patterns of distribution among the mammals studied. Some species, such as red foxes and roe deer, were restricted to glacial refugia in southern areas and expanded as global temperatures warmed. Others, like beavers and lynx, expanded from refugia in the east to the west of Europe. Additionally, some species, including brown bears and wolves, were already widely distributed across Europe during the last ice age.

Interestingly, humans seem to have followed a similar distribution pattern as brown bears during the last ice age. This finding challenges the notion that humans retreated to southern Europe during this period and suggests that they were able to tolerate the harsh ice age conditions in central Europe.

The study raises questions about why ancient humans and other animals in this group lived in such harsh climates instead of exploring more hospitable places. It is unclear whether ecological adaptation or technological advancements played a role in their survival. The inclusion of humans in this distribution pattern could have implications for understanding climate change and human distribution changes.

Overall, the study provides new insights into human adaptation during the last ice age and highlights the resilience of ancient humans in facing challenging environmental conditions. Further research in this area could lead to a better understanding of human evolution and migration patterns.
