Yes, it's clearer now, thank you.
Too bad it's still wrong. Differences between the brains of humans
and most other mammals are small, indeed, but they are important.
For instance, there's a bundle of axons (known as arcuate fasciculus)
connecting Wernicke's area to Broca's area which is essential to
the development of linguistic competence in humans. No other mammal
(other than close primates) have such peculiar organization. This,
of course, not to mention the frontal lobe.
