Modern brains cannot function without nutrients like magnesium and zinc and according to some studies it is likely that the access to certain essential nutrients influenced the evolution of the human brain so that it could become the brain we have today. Nutrients needed for this transition from a primitive ancestor to modern Homo sapiens were (and still are) available in seaweeds said study co-author Ole G.
