Is this a for making natural selection falsifiable?
If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. (Darwin, On the Origin of Species)
Clearly human evolution from that of apes is marked by a dramatic expansion of the human line from that of apes.

With a cranial capacity nearly three times that of the chimpanzee the molecular basis for this giant leap in evolutionary history is still almost, completely unknown. Changes in brain related genes are characterized by debilitating disease and disorder and yet our decent from a common ancestor with the chimpanzee would have had to be marked by a massive overhaul of brain related genes. I propose that a critical examination of common descent in the light of modern insights into molecular mechanisms of inheritance is the single strongest argument against human/ape common ancestry.
Now as far as creation being falsifiable, I don't recall it ever being accepted as a viable theory with regards to evolution. However, the genetic basis of the evolution of the human brain is the key developmental issue with regards to the hominid line.
Nice strawman. No one is claiming a sudden change in brain size. What we can see is a series of fossils with every increasing brain size and an overlap in brain size between steps:
(A) Pan troglodytes, chimpanzee, modern
(B) Australopithecus africanus, STS 5, 2.6 My
(C) Australopithecus africanus, STS 71, 2.5 My
(D) Homo habilis, KNM-ER 1813, 1.9 My
(E) Homo habilis, OH24, 1.8 My
(F) Homo rudolfensis, KNM-ER 1470, 1.8 My
(G) Homo erectus, Dmanisi cranium D2700, 1.75 My
(H) Homo ergaster (early H. erectus), KNM-ER 3733, 1.75 My
(I) Homo heidelbergensis, “Rhodesia man,” 300,000 – 125,000 y
(J) Homo sapiens neanderthalensis, La Ferrassie 1, 70,000 y
(K) Homo sapiens neanderthalensis, La Chappelle-aux-Saints, 60,000 y
(L) Homo sapiens neanderthalensis, Le Moustier, 45,000 y
(M) Homo sapiens sapiens, Cro-Magnon I, 30,000 y
(N) Homo sapiens sapiens, modern
