How Is Artificial Selection Different from Natural Selection?

• Almost free, if one is in the agriculture business.
• Able to produce crops with higher yield, shorter harvest time, higher resistance to pest and diseases and better taste in an inefficient yet somewhat natural way.
• No safety issues such as those brought about by genetic engineering.

Why do different individuals of the same species have different traits?

The variation and distribution of traits in a population depend on genetic and environmental factors. Genetic variation can result from mutations caused by environmental factors or errors in DNA replication, or from chromosomes swapping sections during meiosis.

Why is natural selection not the same as evolution?

Natural selection and evolution are the same thing. No, they aren’t; they really aren’t. Evolution is descent with modification, heritable change in populations of living things. … Natural selection is a mechanism of evolution, a process that leads to shifts in allele frequencies within a population.
