At the moment, there is no definitive answer to the question of nature vs. nurture, there is, however, compelling evidence that the theory of Nature via. Nurture could be the solution.
Nature simply refers to an organism’s biological inheritance (Santrock, 2004). Nature advocates feel that the most important influence on development is our genes. They argue that a genetic blueprint produces commonalities in growth and development. (Santrock, 2004)
Genes are units of hereditary information composed of DNA. They carry information that enables our cells to reproduce and manufacture the proteins needed to sustain life. (Santrock, 2004) In 1991, the science community collaborated to map our genes in a massive undertaking known as the Human Genome Project. In 2001, they succeeded and created a draft of the sequence of our 3 billion bases of DNA. These bases form the human genome. Everyone has a unique genome. (Plomin, 2004) The draft allows scientists to map and identify our approximated 30,000-35,000 genes. (Santrock, 2004) Gene identification is vital, because it allows scientists to the ability to study the generalities of the genome. With it, life scientists are able to find the variations that are responsible for hereditary differences. (Plomin, 2004)
Nurture refers to the environmental experiences on development. The proponents of the nurture view feel that the environment has a greater impact on development.
