A variance is an exception to one or more of the zoning restrictions on a piece of property. A variance is different from a nonconforming use, which permits existing structures and uses to continue when zoning is first instituted.
The book, On The Origin Of Species,  suggested  that organisms evolve through the process of natural selection.opulations evolve as the individual organisms less able to survive in the current environment die and fail to reproduce. That is natural selection.
We now know that the inheritance of acquired characteristics is not an actual mechanism of evolution. Darwin saw that Lamarck had some very good ideas that could lead to evolution. Many of Lamarckâs ideas can be seen in Darwinâs Origin of Species. Lamarck was a believer in immutability. Darwin used this idea to further his research on how species were indeed mutable. Darwin also used Lamarckâs inheritance of acquired characteristics as support for his natural selection idea.
