If we are to believe the latest conclusions of Tony Wright (speaking above in a National Geographic documentary) the left brain hemisphere has not simply dominated a more passive right; rather, over time, it has changed our neurochemistry and neural structures to support its own ascent. In his new book, Left in the Dark, Wright argues that "humanity is suffering from species-wide brain damage" and this damage is the "root cause of our obvious insanity."
According to current thinking cerebral dominance is the product of adaptive selection and has resulted in one side of our brain (the left) acquiring specialist abilities such as speech and rational or conceptual thinking. With these 'advanced' skills the left hemisphere has come to dominate our thinking, behaviour and psychology. In effect our mind and sense of self or who we think we are is primarily a product of the left side of our brain. Of course the conclusion that our left hemisphere has specialised and advanced abilities is, by definition, a conclusion reached by our left hemisphere!
Lets suppose just for a minute that our left hemisphere is a hormonally retarded, structurally damaged, perceptually limited and psychologically deluded version of our right hemisphere and its rise to dominance was driven by fear and the need to maintain a sense of control due to its increasing damage. In effect cerebral dominance is a symptom of a neurodegenerative condition rather than an advanced adaptive trait.
On the one hand, this feels a bit like a rehashing of decades-old complaints about left-brain, dominator culture memes wiping out the goddess herself. But at least these are grounded in accepted science. If anything, it's a left-brain-argued case against the left brain.
New research on trends in adult human height over the last century confirm that, no surprise, humans are getting taller overall due to better nutrition and disease control. However according to the health science group Non-Communicable Diseases Risk Factor Collaboration (NCD-RisC), the gain in adult height varies dramatically by country. From their paper, published in […]
Between April and July, Iran’s salty Lake Urmia changed from a bright green color to a blood red. NASA’s Aqua satellite captured the image above and reported on the science behind the strange transformation. According to NASA, the periodic color change is caused by micro algae producing carotenoids that help with photosynthesis and act as […]
In the late 1960s and 1970s, the mind-expanding modus operandi of the counterculture spread into the realm of science, and shit got wonderfully weird. Neurophysiologist John Lilly tried to talk with dolphins. Physicist Peter Phillips launched a parapsychology lab at Washington University. Princeton physicist Gerard O’Neill became an evangelist for space colonies. Groovy Science: Knowledge, […]
