This theory has met considerable resistance over the years for challenging long accepted anthropological history about the America's. Some reject the theory out of hand and others have grown more accepting of the theory as new evidence emerges.
Which is the norm in scientific investigation. Scientists are normally skeptical and demand evidence. As evidence is found to either support of reject a hypothesis, the hypothesis either becomes more readily accepted or rejected based on this evidence. Most robust theories were heartily rejected when first proposed, such as heliocentrism, oxidation-reduction or evolution. As research continued, more evidence was found and such theories were more heartily accepted.

Since Evolution is only ~90% correct it should be thrown out and replaced by Creation which has even a lower % of correctness. W T Young, 2008
