Maybe not on the macroscopic level, but what about on the molecular level? Is his DNA gets mutated by radiation from computer monitors, does that mean he has "evolved"?

Remember, your body is composed of trillions of cells, each one with its own DNA. So the DNA of one cell can "get mutated by radiation from computer monitors", but this does not affect all of the other cells. Individual cells, or groups of cells can definitely "evolve" within your body. Cancer is when a cell evolves to override the built-in limits on cell growth and this cell and its offspring then grow without limit. So this cell and its offspring are "evolving" within your body. Also, your immune system works in part by having clones of cells which evolve in response to foreign antigens.thetaobums said:Maybe not on the macroscopic level, but what about on the molecular level?

No, physical evolution requires changes in the DNA which can only occur through the process of natural selection over many generations.
While the brain is constantly adapting and developing, this is not considered evolution in the scientific sense. Evolution refers to changes in genetic makeup, not individual development.
No, evolution takes place over many generations and is not influenced by individual lifestyle or environmental changes.
No, there is no scientific evidence to support the idea of humans evolving during their lifetime. Evolution is a slow process that occurs over many generations.
No, evolution occurs gradually over many generations and it is not possible for a human to evolve into a completely different species during their lifetime.
