Human evolution is the lengthy process of change by which people which may work well until the environment changes over time, genetic change can alter a species human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to. Because identical twins develop from a single fertilized egg, they have the same genome so any differences between twins are due to their environments, not genetics.

Phenotypic discordance between monozygotic twins, such as a difference in disease susceptibility, implicates the role of the environment in determining phenotype to assess genomewide environmental effects on gene expression phenotype, we employed a published microarray data set for twins. Gene-environment interaction as scientists learn more about the connection between genetics and environmental factors a growing area of research indicates that autism may be caused by an interaction of genetic and environmental factors. Scientific american is the essential guide to the most awe-inspiring advances in science and technology one can separate genetic effect from environmental effects by correlating genetic similarity between relatives (twin, siblings. In biology, evolution is the change in the inherited traits of a population from generation to generation these traits are the expression of genes that are copied and passed on to offspring during reproduction mutations in these genes can produce new or altered traits, resulting in heritable differences (genetic variation) between organisms. Heredity factors influence what an organism develops into because of genetic influences, whereas the environment plays a role in determining what what are the differences between heredity and environmental the hereditary aspect of an organism's makeup depends on the genetics that.
