Evolution occurs over time due to changes in environment. But what if we could find the gene that is affected by the change in the environment, allowing find a way to prevent that change from occurring? This is exactly what McGill researchers are researching. The McGill team found that by methylating the gene that controls growth of ants (called Egfr), they were able to create ants of different sizes. This could maybe be applicable towards humans as well so that we can prevent natural selection from eliminating any phenotypes over time.
