Evolution: more gaps in foraminifera (Evolution)

DAVID: Very complex article, but it shows that another species, like the whales, have huge gaps between phenotypes. Nothing looks gradual in evolution. Gaps always demand consideration of design.

quote: The researchers think either of two post-Darwinian theories could describe the rapid changes they observed: punctuated equilibrium and quantum evolution. Punctuated equilibrium describes short bursts and subsequent steady periods of morphological change within a lineage. The theory of quantum evolution describes broader, rapid splits into new families, orders, and classes. If the theory fits, the researchers have potentially observed quantum evolution at a species level for the first time. In either case, the researchers believe previous theories of gradual evolution in foram lineages need reassessment.

DAVID: It is best to abandon Darwin's theory of evolution, because staying with his presumptions slows real research.

It is best not to abandon a whole theory because you disagree with a part of that theory. I agree that it is best to abandon Darwin’s theory that evolution only proceeds gradually and nature does not make jumps. Even his "bulldog" Huxley disagreed with him, so what's new?
