You have it backward. If Darwinism is the dominant view, all one has to do it cast doubt on it being the only option possible from the evidence provided.

Did humans evolve from apelike creatures or were they intelligently designed?
According to the standard evolutionary view, humans share a common ancestor with
chimpanzees, and our lineage diverged about 6 million years ago in Africa and then
evolved by unguided evolutionary mechanisms into its present form. This paper
evaluates the assumptions underlying the standard evolutionary model of human
origins and finds “it is full of gaps and weaknesses.” Instead, the authors maintain that
“a unique origin model where humanity arose from one single couple with created
diversity seems to explain data at least as well, if not better.”
After reviewing five main mechanisms invoked by standard evolutionary models of
population genetics to explain human genetic diversity (mutation, genetic drift, natural
selection, recombination, and colonization and migration), the paper observes that:
Neo-Darwinism accounts for the above-mentioned mechanisms I–V, and among
them germline mutations are essentially the only way by which novel DNA can
arise. The theory does not allow for large amounts of new and suddenly
appearing diversity. The reason is that neo-Darwinism is framed within
methodological naturalism. This prevailing approach to science only allows for
natural hypotheses. But if an intelligent designer is invoked as a possible
explanation, and if humanity originates from one single couple, it is possible that
their chromosomes were created with considerable diversity from the beginning.
Thus, the authors report discovery of “a sixth mechanism of genetic change,” one which
is almost universally ignored by evolutionary models: “Created founder diversity is
biologically plausible for DNA of non-sex chromosomes.”
With these mechanisms in mind, the article compares standard evolutionary “common
ancestry” models of human origins with “unique origin” models, where an initial pair of
humans was created with significant founder diversity. There are two main common
ancestry models of human origins: the Out-of-Africa model, where humans evolved in
Africa and then migrated out one single time, and the Multiregional Evolution model,
where humans evolved in Africa but migrated out multiple times, with different human
populations around the world evolving in parallel. There are also two “unique origin”
models: An African Ancestry model, where the initial created pair was located in Africa,
and a Middle East ancestry model, where an initial couple was created in the Middle
East and then humans migrated around the world.
The authors note that the “main argument against a unique origin is that the nucleotide
diversity of human DNA data seems too high in order make a single founding couple
possible.” But they argue it is possible that humans are descended from an initial couple
if “they were created with genetic diversity in their autosomal and X-chromosome
DNA.” What about the location of the initial couple? Non-African populations of humans
seem more genetically similar compared to African humans, and they note that “the
Middle East ancestry model faces some challenges, in particular to explain why African
DNA looks older than non-African DNA.” However, a Middle East origin model could
explain the data if “the age of humanity is much more recent” than common ancestry
models predict, and if African populations experienced higher rates of genetic change
and lived in isolated communities where unique diversity was easily fixed into small
populations. They cite previous literature to support these ideas, making the Middle
East unique origin model a realistic possibility.
The authors conclude that “Any common descent model faces a challenge to explain the
genetic differences rather than the similarities with other species, the consequences of
inbreeding depression and increased genetic entropy, human DNA mixture with archaic
populations, and that our DNA resembles a mosaic of about four founder genomes.”
Thus, they find that “The provisional conclusion is that a unique origin model seems
more plausible.” But which unique origin model best explains the data? They urge
future research is needed to test the two unique origins models, which is what the
authors plan to do in subsequent papers. It may be that multiple models can explain the
data, in which case they conclude that “the common descent model of our origin from
ape-like ancestors can no longer be claimed as conclusive proof that there could not
have been a single first pair.”
