Geographical environments not only play a role in socio-cultural terms, but also in our physical differences depending on climatic conditions. When we look at the obvious contrasts in people’s appearance, geography and so consequences of climate change we can observe.

A research paper in the journal Brain, Behavior and Evolution shows that there are adaptive increases and decreases in human brain size for climate change. In the brain that adapt to climatic conditions discounts has been observed.

Can skull size increase in parallel with excessive intelligence? What does the size of the brain and skull mean intellectually?

External factors such as living conditions people are exposed to and environmental differences in their geographic regions morphological features leads to segregation. Changes in homologous cells carried by humans and part of the Homo sapiens species cause changes in several structural features, such as the anatomy of the skull and teeth.

The anatomical structure that makes us think that people with a large head or broad forehead have larger brains and are therefore more intelligent is a general consensus among people. psychological connotation can cause. You can check out the content we’ve created on this topic;

Many resources have been used for the research. Fossils and climate calculations from thousands of years ago were compared for temporal consistency.

Stibel, who grouped the fossils according to their age, conducted his analysis using four different fossil age categories. The skull and brain volumes of the fossils were calculated in relation to their body size. A total of 298 skull measurements were made. Brain size estimates by comparing body and skull sizes of cranial capacity measurements obtained.

Four climate records were then compared, including temperature data from the Antarctic Ice Core European Project (EPICA) Dome C in Antarctica. In the study, which involved examining 298 samples from the past 50,000 years, Jeff Morgan Stibel, hot climate average during periods a significant reduction in brain size revealed that.

The human brain shrinks when exposed to hot climates! The biggest factor in brain shrinkage is actually the climate changes we are exposed to.

Jeff Morgan Stibel’s research paper, published in 2022, is lower compared to four climate records. cold climate The brain size of people exposed to environmental conditions is larger than average than those living in warmer climates. taller it could be seen.

In short, as the climate warms, the study concludes, the brain getting smaller. Also Stibel; revealed that humidity and precipitation levels also influence brain development, albeit to a lesser extent than temperature.

There is talk of the possibility that global warming could shrink our brains. We may face major problems in the future.

Humans have just over 10.7 percent in average brain size, especially during the Holocene warming period, which occurred about 17,000 years after the last Ice Age, the study said. a significant drop they lived. But changes in brain size usually occur thousands of years after climate change, according to Stibel. It has therefore been shown that several generations are required for the possibility of adaptation at the species level. These results revealed by Stibel global warming possible on human cognition. harmful consequences also expressed concerns.

Stibel noted that even a small reduction in brain size in modern humans is an important, but unknown, significant physiological consequences claims it could. And as is well known, Stibel also has indirect climate effects. technology and culture He states that non-climatic factors, such as
