In Mendel's day, most biologists observed nature and then philosophized about it and tried to concoct clever explanations for what they saw. Geneticists were influenced by their observations of human traits which were more complex than they could appreciate. Mendel was lucky to attend a University in a place and time where revolutionary ideas were circulating about how to do science. Mendel learned that you could use simple organisms as models, and design experiments to test hypotheses. At the time experimental biology was only a couple of decades old, and mostly confined to developmental biology. Also, in other sciences a revolution was happening that placed an emphasis on quantitative science, and the use of statistics. Mendel designed experiments using well established strains of peas. He collected the offspring and rather than making general observations he counted them. He then normalized the data, meaning he divided all of the classes of offspring by the smallest number so he could express
