Part of what makes Krubitzer so fascinating a scientist is that she can describe this from a variety of perspectives, from the genetic modifications that are involved in brain evolution to the changes in neural development that can occur to the animal behavior that is exhibited.
Krubitzer sees all mammalian brains as having "a common plan of organization that was inherited from a common ancestor." While she admits that there's no way of knowing what that ancestor was, she says that its brain type was probably closest to that of a hedgehog.
Krubitzer's egalitarian view of the evolutionary tree caused her to conclude in her most renowned paper in which she most succinctly summarized her findings--"The Organization of Neocortex in Mammals: Are Species Differences Really So Different?"--with a quotation from a naturalist writing from Cape Cod in 1949.

 Krubitzer Receives "Genius" Award: UC Davis Biological Sciences Newsletter - Summer 1998   (Site not responding. Last check: 2007-10-26)
Leah Krubitzer, assistant professor of psychology and member of the Center for Neuroscience, received a 1998 MacArthur Fellowship for $240,000 from the John D. and Catherine T. MacArthur Foundation.
Photo: “Genius”-award winner Leah Krubitzer (right) humorously explains the differences among animal brain abilities to Chancellor Larry Vanderhoef (second from left) and Provost and Executive Vice Chancellor Robert Grey (far left) during a June reception in her honor at the Center for Neuroscience.
Krubitzer was surprised and deeply honored to receive the MacArthur Fellowship, but downplayed her role, saying she benefited from past research and, primarily, her “fantastic” laboratory staff.

It is this question that has propelled Krubitzer's lifework for nearly a decade and a half--work that has now earned this 37-year-old neuroscientist one of this year's MacArthur Fellowships, popularly known as a "genius grant." She was honored for her leading-edge research into the evolution and development of mammalian brains.
A significant component of Krubitzer's "genius" is her ability to conceive original questions that range across any number of highly specialized fields, from neurobiology to evolutionary theory--and to devise experiments that yield interesting results.
To answer this question, Krubitzer has spent most of her adult life investigating the structure and organization of brains across the mammalian kingdom, from rodents to duck-billed platypuses, from the smallest neuronal connections to the most complex resultant behavioral capacities.

Krubitzer carries out a program of research dealing generally with the functional organization of the somatosensory cortex as well as evolutionary principles that have determined the complexity of neocortical sensory systems.
By standardizing stimulus parameters across monkey and human experiments, Dr. Krubitzer and colleagues believe that they can interpret results of humans in a broader framework in which the details of organization and connections are determined in monkeys.
Dr. Krubitzer and colleagues study primitive mammals, such as monotremes, marsupials, insectivores and edentates, whose ancestors branched off very early in evolution, to infer the primitive or early stage of neocortical organization in mammals.

In another experiment, Leah Krubitzer, a professor of psychology at the University of California, removed large pieces of the brains of newborn marsupials.
Once the marsupials became adult, she examined the brains again and found that they had organized themselves in such a way that the visual, auditory, and other somatosensory areas were all in the same relative positions that they would occupy in a normal brain, but they were smaller, commensurate with the total space available.
