D. Differential survival and reproduction

Asked by sjj89

Answer (2)

The factor that is NOT necessary for evolution by natural selection is genetic drift. Evolution by natural selection requires heritability of traits, variation in traits, and differential survival and reproduction. Genetic drift, while it can influence populations, is a random process and is not essential for natural selection. ;

The factor that is NOT necessary for evolution by natural selection is genetic drift. Natural selection requires heritability of traits, variation in traits, and differential survival and reproduction. Genetic drift is a separate mechanism that affects allele frequencies randomly and independently of natural selection processes.
