do you think modern medicine and technology hinder evolution?

[just curious]

consider the appendix. it's a rather useless organ. a small percentage of the population is actually born without an appendix. now consider this, if we lived in a world without any knowledge of medicine, isn't it reasonable to assume that it is likely those with appendixes would die off from appendicitis. and those without an appendix would stand a greater chance of survival than those with an appendix, and thus they would be more likely to pass on the "no appendix" gene. so how would this not be a form of evolution?
horsy, no, not everyone is born with an appendix, just as some people are not born with other organs. do a little research outside of the bible next time before you answer. this is the biology section, not the religion section.
