The spontaneous enhancement in the size of the brain and of the skull, as well as the complexity of the neural network in the brains of hominids, has resulted in longer infant care and gestation period. In human beings, the development of the brain is only 25 percent complete by the time of birth, in comparison in the primates one can witness 45 percent of the development by the time of birth. In humans, the postnatal development of the brain requires more infant care period that plays an essential function in the development of the brain. This enhanced duration of the development of brain has led to enhanced size of the skull and evolution of modern-day man.
The other answer is incorrect.
I just took the quiz and the correct answer is B.
The gestation and infant care period increased to allow the brain to develop.
The correct answer is - The gestation and infant care period increased to allow the brain to develop.
With the constant increase of the size of the skull and of the brain, as well as its ever growing complexity of the neuron network in the hominid brains, the result has been longer gestation and infant care period.
This has been the result because such a large and complex brain needs much longer time to fully develop. That has made the newborn and afterwards the youngsters, to be totally dependent on the adults, to a point where the hominid youngsters were still not well developed while other species have born, grown, and died.
Hope this helped
fossil's are like over rated rocks like low key not gonna lie i don't get why we can't just call them old rocks like for real i mean i call my grandpa and grandma that smh
