Genetics and the Origin of Species natural selection, and speciation throughout his book to explain habits of populations and the resulting effects on their genetic behavior. The book explains evolution in depth as a process over time that accounts for the diversity of all life on Earth. The study of evolution was present, but greatly neglected at the time. Dobzhansky illustrates that evolution regarding the origin and nature of species during this time in history was deemed mysterious, but had expanding potential for progress to be made in its field. In Darwin's theory of natural selection, more organisms are produced than can survive. Some have variations
Systematics and the Origin of Species important and useful idea in biology, particularly for animal speciation. In December 2004 the National Academy of Sciences held a colloquium in honour of Mayr's 100th birthday. "Systematics and the Origin of Species: On Ernst Mayr's 100th Anniversary" was also published in commemoration.
