Contemporary evolutionary theory essentially says that organisms adapt to meet the demands of their environment. It’s very hard to tack down a time frame with it. I personally believe evolution increases as population values decrease, based on evidence I’ve seen. These findings do not shatter contemporary evolutionary beliefs, because a time frame for evolution is not standardized. There are multiple theories on how long evolution takes or what specifically speeds an evolutionary step.
