Scientists with the answer to the scientific problem of how humans got the ability to speak. Researchers from the University of Lyon in France discovered how humans got the ability to speak through the study of the brain. The discovery provides new insights into the evolution of the trait that changed humanity: speech. The study of the scientific team was published in the famous journal "Communications Biology". The study provides crucial clues as to how the ability to make complex sounds came about in human evolution. while questioning current theories

It is also interesting to find out. the current dominant argument is that the special structure of the vocal cords is the reason for the emergence of speech. Although the specificity of vocal tracts led to the emergence of speech, it is clear in the new study that the complex specificity of brain structures is also crucial in the evolution of speech.

finding that the size of the prefrontal region of the frontal operculum (PFOP), located in the ventrolateral prefrontal cortex of the human brain, is the main reason for the evolution of speech in humans; PFOP is associated with the cortex. It is also noteworthy that PFOP is located near Broca's, which is a crucial factor related to speech ability in the brain. PFOP plays an important role in the coordination of dialogue-related activities. The researchers found that the PFO also plays a fundamental role in codifying the relationship between Broca's parts in the temporal lobe, which analyzes information. The prefrontal cortex aids in handling the elements necessary for speech that set humans apart from other primates.

Prefrontal cortex The extent of the frontal operculum is only recently recognized. this feature is only for Homo species. position to further study the complex neural systems underlying speech

The prefrontal region is fully developed in humans but only partially developed in chimpanzees; other monkey species do not have this region. Correlations between the rate of development of the frontal operculum within the prefrontal cortex and voluntary control of their larynx and facial muscles in chimpanzees; in humans, however, due to the full  This suggests that this unique brain structure is not limited to the modern human race and may be found in various Homo species.

burned in this month of 2023, NASA's shocking report says…

Delhi: American space agency NASA says that 2023 will be the hottest month in modern history. NASA report that July 2023 was the hottest month in a century and a half. NASA's Goddard Institute came to this conclusion after examining data from 1880.

The regions of South America, North America, North Africa and the Antarctic Peninsula have felt the power of this heat the most. According to the NASA report, an increase in the average temperature of up to four degrees Celsius was felt in these areas.
