According to the passage, Wilhelm His's work involved —-.
Scientists have thought about the brain's intricate form for centuries. In the early 1800s, German physician Franz Joseph Gall proposed that the shape of a person's brain and skull spoke volumes about that individual's intelligence and personality which is a theory known as "phrenology". This influential, even though scientifically unsupported, idea led to the collection of ■criminal", "degenerate" and "genius" brains. Then, in the latter part of the 19lfl century, Swiss anatomist Wilhelm His claimed that the brain develops as a sequence of events guided by physical forces. British polymath D'Arcy Thompson built on that foundation, showing that the shapes of many structures, biological and inanimate, result from physical self-organization. Provocative though they were, these early suppositions eventually faded from view. Phrenology became known as a pseudoscience, and modem genetic theories replaced the biomechanical approach of the IS"1 century and furthered our understanding of the structure of the human brain. Thus, no matter how exciting the theories may be more reliable information is a prerequisite for their acceptance.
