Summary
Cultural evolution traces freedoms from ancient climates to modern autonomy. Lactose tolerance, linked to specific climates, paved the way for resources and individual choice in encultured societies.
Area of Science:
- Evolutionary Anthropology
- Cultural Evolution
- Human Genetics
Background:
- The origins of cultural evolution and encultured freedoms remain largely unknown.
- Understanding the deep historical roots of autonomous individual choice is crucial.
Purpose of the Study:
- To illuminate the evolutionary pathways leading to encultured freedoms.
- To investigate the role of historical factors, including climate and genetics, in shaping societal values.
Main Methods:
- Analysis of diverse data sources across 108 Old World countries.
- Tracing a sequence from ancient climate patterns to modern encultured freedoms.
- Examining the historical link between lactose tolerance and resource availability.
Main Results:
- Lactose tolerance historically peaks under two distinct climate conditions.
- A specific climate-linked lactose tolerance variant correlates with industrial resources and modern freedoms.
- A gene-culture coevolutionary model is proposed, linking climate, genetics, and freedom.
Conclusions:
- Ancient climate and lactose tolerance are significant factors in the evolution of encultured freedoms.
- A novel thermo-hydraulic theory of freedoms is introduced, emphasizing gene-culture coevolution.
- The study provides insights into the deep historical origins of autonomous individual choice.

Global Climate Change
29.0K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

One-Degree-of-Freedom System
853
In mechanical engineering, one-degree-of-freedom systems form the basis of a wide range of electrical and mechanical components. Using these models, engineers can predict the behavior of various parts in a larger system, which gives them insight into how different forces interact with each other.
A one-degree-of-freedom system is defined by an independent variable that determines its state and behavior. One example of a one-degree-of-freedom system is a simple harmonic oscillator, such as a...

Degrees of Freedom
7.2K
The degree of freedom for a particular statistical calculation is the number of values that are free to vary. Thus, the minimum number of independent numbers can specify a particular statistic. The degrees of freedom differ greatly depending on known and uncalculated statistical components.
For example, suppose there are three unknown numbers whose mean is 10; although we can freely assign values to the first and second numbers, the value of the last number can not be arbitrarily assigned.

What is Climate?
20.9K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.
