In the early 1940s, the studies about the human brain or any brain suggested that the human brain is a blank slate that can be filled with information throughout life. And it was vastly believed that what is fed will fill the empty space.
In the 1960s, Peter Marler, a young British biologist, known for his animal sign communication researches, and a professor of neurobiology, physiology, and ethnology at the University of California, Davis, became obsessed with songbirds.
During his botanical field studies, he realized that the songbirds of the same species had a different dialect according to the part of the city they often lived. Simplifying into as us humans have different dialects around the world.
Further observatory results of young Marler, concluded that the young white-crowned sparrows learn the dialect by listening to its parents and fellow neighboring locale songbirds. Specifically between it’s first 30- 90 days of being born.
Leading on his curiosity to as which, he isolated young (30 – 90 days old) songbirds and exposed them to a different dialect of a neighboring town instead of their own parents’ dialect. The birds learned the new dialect which they were exposed to.
Next, he isolated another group of the same species songbirds but this time he exposed them to songs of an entirely different sparrow species. The songbirds did not learn foreign songs or the new dialect but their very own.
The final conclusion to the long successful experiments was that there is an existing neural restriction in each and everybody from the time of birth which results in not allowing to learn a different species dialect.
His research on different animal sign communication and practical experiments helped to discover the neurology behind the human brain to a great extent as even today.
The human brain in one is unable to learn any other animal dialects. One may recognize gestures and behavioral patterns but, humans cannot communicate with another animal as an animal of the same species does.
Even if being isolated from birth with a certain animal, the human brain cannot pick up the sounds of a different species as per the scientific information today. Science isn’t sure if this is possible yet!
But, human being brought up in a foreign locale from 1 to 6 months old, can learn the foreign dialect by listening and engaging.
Question is, how does the brain recognize this difference and act according to the restrictions?
This question, questioned the initial theory of a blank slate brain as to why, if any brain can learn and adapt to what is fed to it, why can’t we purposely consume human feces?
No matter how far the science goes, no human brain can be convinced to consume its own feces on the right mind and the same goes for why our senses work the way it does.
That’s when the Peter Marler theory came into highlights. The brain does content of neural restrictions from the beginning not only in the brain but also on other recognized body systems as well.
But where do they come from?
I will write to you in my next article as soon as possible.
