Lucy was not that smart as the Great Apes of today


The researchers have discovered that the first human beings such as the popular ‘Lucy’ were not that really smart as the enormous apes. Using the new methods, they had been able to identify that the earliest human beings did not have that similar flow of blood into the brain like the modern apes, that they calculate, which means that the pre-humans would not have had that similar level of intelligence, being said as the modern gorillas. As an outcome of the study, the view of the development of the early human beings may have to alter.

The research has been carried out in Australia at University of Adelaide. It has been led by the evolutionary biologist, Professor Roger Seymour. Mirage News reported that it has been “conducted through the partnership with Evolutionary Studies Institute in University of Witwatersrand”. The study sought to approximate if the pre-humans has been as intelligent as the recent great apes, through measuring the flowing of the blood to a cognitive part of the brain instead of the mass of the craniums.

Brain activity and the blood flow

The group sought to measure a brain metabolic rate or the BMR, by approximating the ratio of the blood flow in the early human beings. Based on the Proceedings of Royal Society, this “can be, the better correlation of the cognitive ability than the brain size alone”.

It is because this measures a synaptic activity that is “indicative of mutually the rate of metabolism of the brain and the level of intelligence” stated by the Daily Mail. This team had to increase the latest equation that will measure the blood flow in the cranial cavities.

The Great apes are even smarter than the early humans

Professor Roger Seymour said that “the study showed that the cerebral blood flow rates of the human ancestors drops well underneath the facts taken from the non-human, modern primates” base of the UPI.com. It is despite the truth that an Australopithecine brain has been of similar size as the latest gorilla brain.

The gorilla Lucy was discovered in Ethiopia in 1974 and is thought to be about 3.2 million years of age. From the latest study, it might appear that she had not been as intelligent as the modern species of the great ape. We are then aware that the gorillas are very smart, such as the popular Koko who discover too many signs in the sign language while at the captivity.

This dares notions of the evolution

Usually it had been considered that since early humans had larger brains than they were wiser, leading to the assumptions that they were best able to adapt into the environment and it is what created them so successful. Professor Seymour has quoted as stating that the case “cast doubt above the notion that a cognitive and neurological trait of the recent great apes sufficiently represent the capabilities of the Australopithecus species,” from Irish News.com. It may mean that the theories of cognitive superiority of the early humans of the history of the world, when compared to recent modern primates were all incorrect.
