The Hadzaa are a primitive tribe that develops their ancestral way of life in a region of Tanzania .They are hunter-gatherers and at the same time, a curious challenge for anthropologists and biologists.noted in the title of this article, this tribe has the unique feature of hunting like sharks , like sharks.
Are we wrong? Obviously we are on a terrestrial stage, there is no water or dams that escape by moving their fins, however, there is something that the Hazdaa share with the sharks , and in fact, also with the bees …
Intrigued? Don't worry, we give you all the information below...Join us!
Levy's flight
Levy's flight is a mathematical pattern that defines as some species usually move to achieve certain ends.When hunting to survive, it is most likely that if we were what we would do in the first place it would be to analyze what our prey is, what customs it has and where it usually moves.
However, in the case of the Hadzaa tribe their survival methods follow a pattern between chaos and strategy, and which scientists consider almost genetic and ancestral, that is, they follow a «primitive strategy» that this population shares in turn with sharks and bees.
The sharks, for example, follow a very specific pattern of movement to reach their vic Timas.They give short movements over very limited distances.They go back and forth in a repetitive way to probe randomly. Later, this first repetitive strategy and staged in a specific area, gives way to longer movements, to travel a longer distance.This is what is known as Levy's Law.
We could say that this formula also frames chaos theories, and phenomena such as earthquake analysis , financial mathematics, or astrology.That is to say, in the first place or we short movements that start randomly and then execute longer activities or phenomena in a studied way .Something we usually observe in bees and wonderful sharks.Surely you will have seen them in some documentary.They usually move rhythmically, here and there over very short distances analyzing by means of their fine sensors, or ampoules of Lorenzini. Later, if nothing capt in your interest, they will leave in a "default" direction.
With the Hazdaa the same thing happens.We, for example, would build traps, control a specific hunting territory and go to that area every day.This tribe , on the other hand, every day it executes a mixture of long trajectories and very short random movements. And they do it both to hunt and to look for fruits, seeds or plants. Does this mean that they do it wrong? That your technique is ineffective? Not at all.Scientists tell us that this movement, despite not being associated with cognitive abilities, is actually a fundamental law to study an area with unknown distribution of resources.
That is, we never know what will happen in this territory where the Hazdaa live. The prey to hunt can arise at any point and at any time, so ideally, is to combine punctual random with long distances studied and preset in search of new points of interest.
At first glance, this may not seem like anything special, but in reality, it is very effective to move by this type of means, and that in turn, would show us that we have a gene that we share with species such as sharks or bees.Something so curious or as fantastic, there is no doubt.
