The study found uniquely human sulci help clarify the evolutionary line

The researchers found that, STAP in various populations in the brain are very clear, whether the fetus is still in the womb, or has reached the ripe old age of the elderly. This suggests that the genetic characteristics of the groove should be human. Researchers determine that this genetic characteristics of our species might be able to provide a unique perspective on understanding cognitive development and social communication and cognitive abilities such issues. Since this feature is not present in other primates, this finding might be able to tell us why the human brain is so unique. The researchers said they will do further research to find the cause notch gene appears to help people better understand the structure and function of this unique.
