Definition
Glossary of Plant Systematics (1st ed.) by Simpson (2006)
- Descent with modification; the transfer of genetic material from parent(s) to offspring over time, with a corresponding change in that genetic material.
Glossary of "Evolution (3rd ed.)" by Futuyma (2013)
- In a broad sense, the origin of entities possessing different states of one or more characteristics and changes in the proportions of those entities over time. Organic evolution, or biological evolution, is a change over time in the proportions of individual organisms differing genetically in one or more traits. Such changes transpire by the origin and subsequent alteration of the frequencies of genotypes from generation to generation within populations, by alteration of the proportions of genetically differentiated populations within a species, or by changes in the numbers of species with different characteristics, thereby altering the frequency of one or more traits within a higher taxon.
