Volume 2 is concerned with how species inherit particular characteristics Darwin first published his 'provisional hypothesis' of pangenesis. This theory of 'gemmules' was not met with much acceptance and today is not valuable as scientific explanation but it was important in laying down the key questions that needed to be answered regarding the processes of genetic inheritance. Darwin also used volume 2 to challenge the theories of evolution by design expounded by the botanist Asa Gray. Darwin's arguments were some of the very first in a long debate that remains hot today. The work was intended to counter critics of Origin of Species particularly those who questioned the reality of variation and the mechanism of inheritance. It is considered a classic in evolutionary biology providing crucial support for the theory of evolution. It laid groundwork for modern plant and animal breeding and genetics. ; ; 568 pages .</p> Orange Judd & Company hardcover
