What did the Scottish geologist and plant-breeder James Hutton claim about a possible evolutionary mechanism similar to natural selection (many years before Charles Darwin and Alfred Russel Wallace)? that only natural selection, not artificial selection, could lead to improved plant and animal species that selection for heritable variation could improve species, but not varieties, of plants and animals that selection for heritable variation could improve varieties, but not species, of plants and animals that only artificial selection, not natural selection, could lead to improved plant and animal species that artificial selection of crops and livestock improves plants and animals more than natural selection
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
