This response is for Dbass, but addresses a few similar arguments in this thread.
Evolution is still alive and kicking. Ill give you a well studied example-
The sickle cell trait is conveyed by an incompletely dominant gene. People with two copies of the trait (one from each parent) suffer from sickle cell anemia, people with one copy, do not suffer from an acute disease, and are termed 'carriers'. Carriers have fewer functional red blood cells than normal people, but are able to live completely normal lives. Their unique blood make up conveys resistance to malaria.
The frequency of the sickle cell allele is many times higher in areas where incidence of malaria is high. This is an example of adaptive evolution, which occurred relatively recently. This is not the only epidemiological example that demonstrate the persistence of evolution.... the evidence is our there
edit: the first attempts at a post were a mess
