Gregor Mendel, a scientist, used pea plants in a study to find out how heredity is passed through generations. He found out through observation and data collection how each trait is passed and came to conclusions no one before him had. Before his studies, we did not know as much or nearly at all about how traits were inherited from parents to their offspring. His study of these plants helped to shape the ideas we have about inheritance today. With his help we have developed a continuously changing concept of inheritance. In the future our ideas about inheritance will be different by cause of them changing in the past, the scientific method proves it, and new discoveries may be made. Our ideas about science are constantly evolving. An example of science changing is radiation being used to treat cancer. In the early 1900s, radiologists would test the strength of the radiation before administering it to patients. This led to radiologists discovering high radiation exposure could cause cancer, not only cure it. The general thought before this realization was that the radiation would only kill cancer cells and not create them (Cancer, 2014). This turned out to be wrong, just like other science concepts can be. Another believed fact that was changed was the ideas of inheritance previous to Mendel’s observations. Before this, people knew that children looked similar to their parents, but didn’t understand the science of it (DNA From The Beginning, 2002). This has since changed as…
