Recent Problems in Evolution
Studies published over the last few years (1990-2004) have demonstrated increasing numbers of problems associated with the theory of evolution. These studies have been done by scientists that believe that the theory of evolution is true. To a large degree, they represent a small amount of the "negative" research in evolutionary studies. Most investigators are not willing to submit a manuscript for publication that contradicts the current dogma. Reviewers of such manuscripts are unlikely to accept a negative study for publication unless a suitable alternate hypothesis is stated and supported by extensive data.
