For any who are interested in evolutionary theory, I recommend you subscribe to Evolution News (it’s free), published by Discovery Institute, a leading Intelligent Design thinktank. You will be kept abreast of such developments as described in “Neo-Darwinism Must Mutate to Survive,” a peer reviewed article which concludes that macroevolutionary changes cannot be explained as simply an accumulation of microevolutionary changes.
A review of the article can be found here:
Of course, accumulations of microevolutionary changes has always been the presumed mechanism driving evolution. Without a mechanism, there is no theory of evolution, because the mechanism is the theory.
