Poverty may have direct implications for important, early steps in the development of the brain, saddling children of low-income families with slower rates of growth in two key brain structures.
Medical researchers at the University of Alberta recently published findings showing that brain development is delayed throughout childhood and adolescence for people born with Fetal Alcohol Spectrum Disorder (FASD).
The hobbit human, a small-statured race that evolved separately from our own ancestor Homo erectus on an island of the Indonesian Archipelago some 50,000 years ago, has been discovered by Japanese scientists to have a bigger brain than once believed.

An Evolutionary Biologist at The University of Manchester, working with scientists in the United States, has found compelling evidence that parts of the brain can evolve independently from each other.
Scientists using magnetic resonance imaging (MRI) observed that the brains of children with autism spectrum disorder are larger than those without autism, but this difference appears related to increased rates of brain growth before 2 years of age.
Whether cognitive differences exist between modern humans and Neanderthals is the subject of contentious disputes in anthropology and archaeology.
The brains of newborn humans and Neanderthals are about the same size and appear rather similar overall.
For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals.
Packs of hunting dogs, troops of baboons, herds of antelope: when people observe social animals, they are often struck by how intelligent they seem, and recent studies suggest that sociality has played a key role in the evolution of larger brain size among several orders of mammals.
