There is no simple answer to this question as medical technology can be seen as both advancing and preventing evolution in humans depending on how you look at it. From one perspective, medical technology is advancing evolution by allowing humans to live longer and healthier lives, which gives them more opportunities to reproduce and pass on their genes. Additionally, medical technology can be used to specifically select and create desired traits in humans, such as choosing the sex of a child or choosing to have a child with a specific genetic disability. However, from another perspective, medical technology can be seen as preventing evolution by keeping humans alive who would otherwise die and by correcting genetic disorders that would otherwise be passed on to future generations.
