Which of the following statements accurately describes the comparison between the avian pallium and the human cerebral cortex, based on the provided text?

  • A: Both the avian pallium and the human cerebral cortex play similar roles in higher cognitive activities despite their structural differences, evolving from a common ancestor with a nuclear organization of neurons.
  • B: The avian pallium is structurally identical to the human cerebral cortex, both featuring six parallel layers of neurons.
  • C: Only the human cerebral cortex is capable of sophisticated information processing, as birds lack a convoluted cerebral cortex.
  • D: The common ancestor of birds and mammals had a layered brain organization, which was subsequently transformed into a nuclear organization in birds.

Explanation

The text explains that despite structural differences nuclear in birds, layered in humans , both the avian pallium and human cerebral cortex play similar roles in higher cognitive activities. It also states that the common ancestor of birds and mammals had a nuclear organization of neurons, which birds retained, while mammals developed a layered one.
