5 Puzzling Questions about Human Existence

human existence mystery1. How did life originate?

For 80 years now we are told that the first self-replicating molecules appeared in the primordial soup in the Earth’s shallow waters, which happened 4 billion years ago. This “soup” was composed of amino-acids, polypeptides, and nitrogenous bases of nucleotides formed as a result of electrical charges, high heat and cosmic radiation.

However, the experiments to replicate similar processes have given mixed results: the basic monomers began to form substances that prevented the expected complexity to exist in this “soup” of polymers.

Later, the problem seemed to have been simplified by the “RNA world” hypothesis, but the probability of spontaneous formation of RNA, which would Continue reading

Myths and Truths about Brain Hemispheres and Their Functions

brain hemispheresOver the last decade great attention to the functioning of the cerebral hemispheres and its effects on the process of learning was paid. This interest has to do with the fact that traditional teaching models are based on the functioning of the left hemisphere i.e. the development of language and logic, without taking into account the characteristics of the right hemisphere, such as intuition, spontaneity, and imagination.

Although the famous French mathematician Poincare argued that “the logic proves but the intuition creates” and although the Hungarian scientist Michael Polanyi talked about mental beauty and passion in the process of knowledge discovery, only recently science began to recognize the role of Continue reading

Evolution and Human Consciousness: Unanswered Questions

human brain potentialIntelligence emerged as a result of a genetic accident – this is the most common conclusion among researchers who study human evolution. Their studies would also have to answer why the brain remains, in spite of all the important tasks it performs, a sleeping giant since neurological research shows that we only use 5-7% of its potential.

Human intelligence is the result of a huge number of interconnected neural functions, producing manual dexterity, a highly sophisticated and clear stereoscopic vision, recognition and use of complex symbols (abstract thinking) and a very long memory. Nowadays, the predominant scientific view is that there are many degrees of complexity intelligence (some of which are present in all mammals) and that humans share with apes and dolphins a lot of characteristics that, until recently, were considered unique to human beings.

The QWERTY effect: how typing affects our brain

qwerty effectBefore you start reading this text, look carefully at the keyboard of the computer you are using right now. Pay more attention to the left side, just under the key “1”.

British and American scientists found out that people prefer words consisting of letters located at the right side of the keyboard than at the left one. It has to do with the Continue reading
