The two are attempting to generate new brain parts, or functional regions, in the brain, by significantly modifying the organization of an existing brain in a manner consistent with actual brain evolution. One such alteration includes changing the actual size of the neocortex, a portion of the brain that has increased dramatically in humans. The neocortex is thought to be involved in perception, cognition, learning and memory. An outgrowth of all Leah Krubitzer's work is her appreciation for the incredible complexity of all life forms, of their evolutionary success. When it comes to humans' special capacity for language, Krubitzer doesn't see it as necessarily so special.
Animals have pretty complicated communication systems.
Ours may be the most complicated. But I don't know of any species of mammal that doesn't communicate at one level or another. She regards the attempt to measure other animals by human standards as a fundamentally flawed view of life. We humans are way up here and every other animal is a degraded form of us. But they've evolved independently.
