researchers in this paper conclude that : ( there is a serious waiting time problem that can constrain macroevolution. Our studies show that in such a population there is a significant waiting time problem even in terms of waiting for a specific point mutation to arise and be fixed (minimally, about 1.5 million years)... To the extent that waiting time is a serious problem for classic neo-Darwinian theory, it is only reasonable that we begin to examine alternative models regarding how biological information arises. )

so how can macroevolution have enough time to occur ?
Hello Amr; The only familiar place that I encounter the "waiting time problem" is in the creationist literature. In papers published by anthropologists and evolutionary biologists I don't think that you will encounter the term. Please correct me if I'm wrong. best regards, Jim Des Lauriers
