== Scientific developments leading up to the theory ==

Early in the 19th century, scientists had already recognized that Earth has been inhabited by living creatures for a very long time. On the other hand, they did not understand what mechanisms actually drove [[Biodiversity|biological diversity]]. They also did not understand how [[Trait (biology)|physical traits]] are inherited from one generation to the next. [[Blending inheritance]] was the common ideal at the time, but was later discredited by the experiments of Gregor Mendel. Mendel proposed the theory of particulate inheritance by using [[pea]] plants (''Pisum sativum'') to explain how variation can be inherited and maintained over time.{{cn}}

** Offspring are a blend of both parents (i.e. in modern terms, alleles would blend together to form a completely new allele)

** The characteristics of the blended offspring are passed on to the next generation
