Testing Darwinism versus Cosmic Ancestry
What'sNEW since 2002

Most of the past theories of science are already suspected of being false: there is presumably every reason to anticipate that current theories of science will suffer a similar fate — Larry Laudan (1)

Where We Agree With Darwinism

We do not doubt that natural selection, operating on the phenotypic results of mutation, recombination, and gene acquisition, plays an important role in evolution. We accept the evidence that natural selection can use genetic changes to produce evolutionary results over time as follows —
  • Small mutations can allow proteins to become optimised for different environments and different species.
  • Point mutations and other simple mechanisms can switch existing programs off and on.
  • Simple mutations could cause incompatabilities that lead to reproductive isolation, or speciation.
  • Symbiogenesis has been important in evolution, as Lynn Margulis says.
  • Horizontal gene transfer can deliver from various sources the components of large genetic programs such as the ones for photosynthesis.

Where We Disagree With Darwinism

Darwinists extrapolate from evidence for the above-listed processes to the claim that these processes can invent wholly new genetic programs that could produce virtually unlimited macroevolutionary progress over time. This leap is unsupported by evidence or logic.

Recently, Darwinists have begun to accept the evidence that horizontal gene transfer can deliver the components of large genetic programs. However, this makes the original source for them even more difficult to explain. How would independently evolving genes, exons, or other lengthy DNA strands gradually acquire the correct sequences needed to serve as components of a genetic program whose function will only be performed when all the needed strands are installed — in a species different from the one(s) in which the strands were written? The correct mutations would not be neutral, so if the strands were active in the donor species, natural selection would surely hinder the process. If the strands were silent while gradually acquiring the correct sequences, the monkeys that can write Shakespeare must have done it.

Cosmic ancestry holds that wholly new genetic programs cannot be invented by the above-listed processes over any period of time. Rather, the strands of new genetic programs must always be imported into a given species by gene transfer mechanisms. (That they were ever invented is an untested assumption.) After transfer, the strands may become properly grouped or assembled by DNA repair and recombination mechanisms using logic analogous to grammar- and syntax-checking in word processing programs. If the imported programs provide an advantage, natural selection will promote the acquiring species. But without a source for new programs, natural selection will soon reach the maximum evolutionary potential of the available programs, and macroevolutionary progress will halt.

The full implications of cosmic ancestry are discussed elsewhere on this website. Here we want to consider scientific tests that could distinguish between the two theories, cosmic ancestry and darwinism.

Test One: Biology

If new programs can be invented by strictly darwinian processes, it should be possible to demonstrate sustained macroevolutionary progress in a genetically closed system. Such a demonstration would confirm darwinism's strongest claims and remove the need for cosmic ancestry's open system.

Unfortunately for darwinism, no such demonstration has yet succeeded. No wholly new genetic programs have been seen in even the best series of biological experiments in genetically closed systems. These have now run for more than 25,000 generations of E. coli, in experiments managed by Richard Lenski of Michigan State and others (2).

This failure is usually ignored, or else explained away — there wasn't enough time, the system wasn't large enough, etc. But the simple fact is that the surest demonstration for vindicating darwinism over cosmic ancestry has not succeeded. This failure leaves viable our contention that sustainable macroevolutionary progress requires a genetically open system.

Test Two: Computer Models

If time is the problem, then a computer model of evolution should be the solution to vindicate darwinism. Computer models can run a generation in a fraction of a second, instead of the hours or days needed for the fastest biology experiments. Yet computer models to date have also failed to produce unmistakable macroevolutionary progress, after sufficiently many trials (3). So the second-best test for vindicating darwism over cosmic ancestry also fails. Most biologists ignore this failure.

Test Three: Reconstructing the Past Genomically

Third-best are historical reconstructions of actual biological evolution based on genomic studies of existing species. To get any result one must assume that today's version and the ancient version of a given species are sufficiently similar, genetically, and that gene transfer and gene loss will not obscure the remote past. Then, if new programs are produced by the darwinian method, their precursors should be present in the genomes of today's species that are ancestral to the one posessing the full program under study. These precursors should exhibit a pattern of gradual construction, one or a few nucleotides at a time, as one ascends through the phylogeny of the program. However, if new programs are imported by cosmic ancestry, the gradual intermediate steps will not be found. Instead, one would observe nearly identical programs, or nothing similar, in the ancestral species (4).

Historical reconstructions like that by Raymond et al. (5) look hard for evidence of gradual construction. Claims of such finds are very few. Instead, geneticists are often surprised to find evidence that new programs were delivered to a species by gene transfer (6). Evidence for transfer and program reassembly supports cosmic ancestry, not darwinism.

NEW 2020: Nowadays, DNA is being sequenced from biological remains tens of thousands of years old. As this continues, the resolution of "test three" should improve, for the near-past at least.

No Good: Reconstructing the Past Morphologically

In the fossil record, some evolutionary traits, like increasing size in horses, appear to arise gradually. Such evidence is used to support the darwinian claim that random genetic processes can invent wholly new genetic programs. But this case is highly inferential. Some morphological changes, like larger size, may not require new genetic programs, but only slight changes in existing ones. And changes that do require new genetic programs, acquired by transfer, might still be designated as gradual if the fossil record is incomplete. Conversely, when the morphological record refutes darwinism, as examples of punctuated equilibrium do, darwinists discount the evidence in various ways.

2022: Now the huge surprise of HGT is no surprise. Now life's early start on Earth / punctuated equilibrium / convergent evolution / the ubiquity of unfamiliar and de novo genes / the huge store of unknown genes in viruses / genes that seem to precede their earthly deployment all make more sense. A theory of evolution that easily accounts for and even anticipates these things is worth considering (excerpt from email to Jim Shapiro).
