When Charles Mendel developed the theory of natural selection in the 1800s he did not include a genetic explanation. True of false?

False. Charles Darwin developed the theory of natural selection in the 19th century, but he did not have a genetic explanation for inheritance as it was not understood at the time. The principles of genetics were later established by Gregor Mendel, whose work on inheritance patterns was published around the same time but remained largely unrecognized until the early 20th century. Thus, while Darwin's theory of natural selection focused on variation and adaptation, it did not include a genetic framework.
