Sweating is a unique and essential human trait. It plays a crucial role in thermoregulation. As our ancestors adapted to life on the open savannahs, maintaining an optimal body temperature became vital for survival. Unlike other mammals, humans developed an efficient cooling system through sweat glands.

Computational methods have revolutionized the study of human evolution. Scientists are now able to reconstruct past environments and climates using computer algorithms. Computational methods have been particularly useful in the reconstruction of ancient climates.

Human evolution in relation to agriculture is fascinating. As the global population has grown, the development of agriculture and civilization has significantly changed our lives.

For good reason, the control of fire is often cited as one most significant milestones of human development. Not only did it provide warmth and protection from predators, but it also impacted the diet, behavior, and social organization of our ancestors.

One of the many unique things about humans is the structure of our hands. This structure gives us the ability to use tools and technology in a way other species cannot. The modern human hand differs greatly from the hands of early hominids. For example, Australopithecines had hands that were similar to other primates, withContinue reading “The Might of the Human Hand”

In the modern world, people are regularly grouped into a race based off of certain physical characteristics, such as skin color and facial features. However, biologically speaking these physical characteristics do not correspond to any meaningful distinctions.

Language is a remarkable human attribute that extends far beyond its function as a medium of communication. It acts as a powerful social glue, binding communities together. Throughout human history, language has had a deep impact on our social interactions and collective identity.

Dogs are called man’s best friends for a good reason. Throughout history, they have assisted humans in protection and hunting. Today many are kept as household pets. It is hard to imagine how they transitioned to this state from being wild wolves.

I recently found out that bonobos and chimpanzees are not only closely related to each other but also two of the closest relatives to humans. One area of difference between the two species is that chimps are very competitive with each other, while bonobos are more empathetic and caring.

Another area of comparison is the production of cortisol. In the combat study, there was a moderate increase in cortisol observed overall. However, there was a very significant difference between the level of increase in amateurs versus those who were highly trained. While the cortisol levels of amateurs jumped to be almost three times asContinue reading “Effects Combat Sport vs. Video Games (Part 2/2)”
