Jellyfish Horizontal gene transfer with the animals is going to turn out to be more widespread than anybody believes now. When that realization comes down, it will definitely change the way people think about evolution. — Michael Syvanen, Professor of Medical Microbiology & Immunology, School of Medicine, University of California at Davis

Syvanen is quoted in Nature's commentary on another example of trans-kingdom horizontal gene transfer (HGT), this one observed by team of evolutionary biologists at the Pierre and Marie Curie University in Paris. They found evidence that an ancestor of cnidarians (sea anemones, jellyfish, corals etc.) acquired an essential gene from bacteria. The gene encodes a subunit of PGA synthease, enabling cnidarians to sting their prey. "The result was a great surprise," says team leader Nicolas Rabet. In cosmic ancestry such results are expected.

We don't want a bunch of theories Woodstock of evolution? That's how Nature descibes a meeting among sixteen leading biologists at the Konrad Lorenz Institute for Evolution and Cognition Research in Altenberg, Austria, 10-13 July 2008. The purpose of the meeting was to go beyond the modern synthesis that has held evolutionary theory together for more than sixty years. This is necessary because the existing theory leaves much unexplained —

  • "When the public thinks about evolution, they think about the origin of wings and the invasion of the land," says Graham Budd, a palaeobiologist at the University of Uppsala, Sweden. "But these are things that evolutionary theory has told us little about."
  • "The modern synthesis is remarkably good at modelling the survival of the fittest, but not good at modelling the arrival of the fittest," comments Scott Gilbert, an evo-devo researcher at Swarthmore College in Pennsylvania.
The participants agreed that such shortcomongs must be carefully downplayed (see right), because "creationists seize on any hint of splits in evolutionary theory or dissatisfaction with Darwinism." Apparently darwinism is still gridlocked and real reform is not imminent. Meanwhile, we noticed a couple of reported comments that are consistent with cosmic ancestry —
  • Stuart Newman, a developmental biologist at New York Medical College, comments "You can't deny the force of selection in genetic evolution, but in my view this is stabilizing and fine-tuning forms that originate due to other processes."
  • To explain the sudden appearance of turtles, Scott Gilbert suggests, "all the genes are probably there already...."

Putative functions
Putative functions of 37 genes acquired from non-organellar sources prior to the split of red algae and green plants.
11 September 2008

...Multiple independently acquired genes are able to generate and optimize key evolutionary novelties in major eukaryotic groups. This conclusion comes from an extensive genomic analysis of an extremophile red alga, Cyanidioschyzon. The two analysts acknowledge that genes may be transferred from organellar genomes or by hybridization, but they exclusively consider gene transfer by other means. Biologists Jinling Huang and Peter Gogarten observe —

  • Some anciently acquired novel genes identified in our analyses appear to be critical for plant development or adaptation.
  • An interesting observation from the studies of HGT in eukaryotes is that the vast majority of well-documented cases involve prokaryotes as donors.
  • It is interesting to speculate whether early eukaryotes continuously obtained genes from a larger prokaryotic gene pool, either individually or occasionally in large chunks....
  • The multiple introductions of the same gene from various prokaryotic sources ...suggest that HGT is a continuous and dynamic process.
  • The barriers to interdomain gene transfer during early eukaryotic evolution might not [have been] as significant as observed today.
  • By acquiring ready-to-use genes from other sources, HGT avoids a slow process of gene generation and might confer to the recipient organisms immediate abilities to explore new resources and niches.
  • It is possible that the identified genes in our analyses represent only the tip of an iceberg for the overall scope of ancient HGT in eukaryotes.
The importance of horizontal gene transfer (HGT) in eukaryotic evolution is becoming better recognized. Meanwhile, the present study admits, HGT already "has revolutionized our view of microbial evolution." These developments confirm a basic prediction of cosmic ancestry, in which HGT is essential for macroevolutionary progress in all domains of life. For strict darwinism, HGT is a surprise no longer easy to ignore.

Tardigrades survived ten days in space on the European Space Agency's Foton M3 mission last September. The vacuum and dryness were well-tolerated by the two species tested, but radiation was lethal to some. Also known as waterbears, tardigrades range in size from 1.5 to .05 millimeter. "This proves that at least some animals can survive the rigors of space flight unprotected." K. Ingemar Jönsson of Sweden's Kristianstad University led the team that designed the experiment.

It is now completely clear that genomic complexity was present very early on — Casey Dunn, Brown University

An international biology team has analysized the genome of a tiny flat marine organism, Trichoplax adhaerens. The species is known to have only four cell types, no head or tail, no stomach, no nerves and no muscles. It reproduces asexually (without meoisis), by fission. Earlier studies of mitichondrial DNA indicated that its phylum, Placozoa, may be the "earliest branching basal metazoan phylum." The new analysis is surprising.

trichoplax and human genes The Trichoplax adhaerens genome contains 98 million base pairs, and an estimated 11,514 protein-coding genes. Unlike other more advanced animals such as fruitflies and nematodes, Trichoplax genes have an intron density (7.6/kb) similar to that of vertebrates (8.5/kb). Many of these introns (82% in conserved regions) occupy the same position and phase as the corresponding ones in humans. Even more interestingly, "Each of the 21 longest gene-rich Trichoplax scaffolds contains segments with a significant concentration of orthologues on one or more human chromosome segments." For example, the illustrated Trichoplax and human segments contain 83 pairs of orthologs, of which the "well-known" ones are connected with red or gray lines (disconnected in our adaptation of this image.)

Most surprisingly, many Trichoplax genes with orthologs in more advanced species code for complex features that Trichoplax itself does not have. For example, the analysis reports:

  • "Trichoplax contains a rich repertoire of transcription factors ...commonly associated with patterning and regionalization during eumetazoan development....
  • "Transcription factors that regulate cell type specification and differentiation in bilaterians are also abundant in Trichoplax....
  • "Trichoplax ... possesses evident homology to bilaterian anteroposterior or dorsoventral axes. Yet, components of a complete ...signalling pathway—used for axial patterning in bilaterians and cnidarians and in demosponge larvae—are present....
  • "Components of other signalling pathways such as the Notch and JAK/STAT pathways are present, but these pathways seem to be incomplete....
  • "...We find various ion channels that are implicated in neural signalling in animals.
  • "Components of neurotransmitter biosynthesis and vesicle transport systems, as well as a putative neuroendocrine-like secretory apparatus, are also found in the genome.
  • "Putative neurotransmitter and neuropeptide receptors are also present....
  • "Synapse formation proteins ...and structural elements of the post-synaptic scaffold known to be present in sponges ...are also found in Trichoplax, including the receptors and channels missing from the sponge genome.
  • "Genes associated with neural migration and axon guidance in bilaterians ...are also present.
  • "Trichoplax reported to lack ...any described extracellular matrix (ECM). Its genome, however, contains a diverse set of genes that code for putative ECM proteins. These include collagen IV, laminin-alpha, -beta and -gamma, and nidogen; however, fibronectin, fibrin, elastin and vitronectin are all apparently absent.
  • "The Trichoplax genome also encodes cell-surface adhesion proteins ...that interact with each other and the ECM in bilaterians, and encodes cytoskeletal linker proteins ...that help organize the actin cytoskeleton and/or transduce signals in other eumetazoans.
  • "Similarly, protein components ...that would permit dual functions of beta-catenin and integrin receptors in adhesion and signal transduction ...are encoded by the genome.
  • "Enzyme families known to modify ECM components and/or signalling molecules in the matrix ...are also present.
  • "...Meiosis-associated genes are found in the genome.
  • "Although the Trichoplax body plan is simple, its genome encodes a rich array of transcription factors and signalling pathways that are typically associated with eumetazoan developmental patterning and cell-type specification. A question remains: what role do these genes have in placozoans?"

Under darwinian theory, natural selection is essential for the composition of genes for new functions. Of course, natural selection can only operate on functions when they are expressed. But apparently, these functions did not begin to be expressed until long after the genes encoding them were extant. Under darwinian theory, something is badly wrong here.

The findings support a basic prediction of cosmic ancestry, namely that all genes are very old.

Bernie Degnan Sponges don't have nerve cells, yet they have genes for directing the formation of nerves. "What was really cool is we took some of these genes and expressed them in frog and flies and the sponge gene became functional – the sponge gene directed the formation of nerves in these more complex animals," says Professor Bernie Degnan (pictured) of the School of Integrative Biology, University of Queensland. His lab is mapping the entire genome of the sea sponge. "We really didn't expect it," he adds.

The data reveal nothing about the origin of these genes, only that they must be older than previously thought. Following darwinian logic the research team adopts a startling conclusion — "The bilaterian neurogenic circuit... was functional in the very first metazoans."

The data are not surprising for cosmic ancestry, in which genes must be available before they can be expressed. If so, sometimes they would reside in species with no use for them, as seems to be the case here.

The origin of new genes in well-documented species of fruitflies is the focus of an exhaustive study by geneticists of the Kunming Institute of Zoology, Chinese Academy of Sciences. They conclude that 5 to 11 functional new genes per million years originate in the D. melanogaster subgroup. Of these new genes —

  • Most arise by gene duplication, either tandem or dispersed. The dispersed ones (which may have originated as tandem ones) are more likely to be retained.
  • 10.2% come from retroposition, the generation of an intronless copy by reverse transcription of mRNA. (This percentage would likely be higher among species with more active retroposons, such as humans and rice.)
  • Surprisingly, 11.9% originate from previously noncoding sequences. They call these de novo genes.
  • "Chimeric structures significantly contribute to the evolution of new genes."
new genes We are very interested in the findings of this study. We specifically want to know if darwinian processes can create new genetic instructions for new functions (new encoded meaning), as is generally assumed. This study does not consider any specific functions, new or not, that the new genes may encode. But with lengthy ORFs and clear evidence of functional constraint, the genes must be doing something. The ones arising from previously noncoding sequences obviously provide something not already expressed in fruitflies. But do the new genes create new meaning?

Other evidence shows that duplication usually allows previously existing functions to segregate and optimize. And retroposition, by itself, creates no new meaning. But duplicates and retroposed genes may acquire extraneous protein-coding or regulatory sequences, and novel phenotypes may emerge. We suggest that these chimeric genes are created by processes similar to those in computer models where shuffling algorithms, like suffling exons, can create variety. But these process have not been shown to create new meaning. They only explore the potential of the encoded meaning that is already available.

The geneticists call new genes coming from previously noncoding sequences de novo. Their nine examples map to homologous noncoding regions found so far only in other insects. Most are present in a fruitfly outgroup, D. yakuba, but one is not — its nearest relative known to have a matching sequence is the honeybee (implicating horizontal gene transfer). And they observe, "Notably, the lengths of all the newly identified de novo genes' protein products are predicted to be longer than 100 amino acids." Of course, a random DNA sequence longer than 300 nucleotides (100 codons) is absurdly unlikely to code for a useful protein, yet these de novo sequences apparently do. They must be not random sequences. Instead they appear to be pre-existing genes not previously expressed in any sequenced species.

In our proposed amendment to darwinian theory, evolutionary advances occur when genetic programs are acquired, reassembled, activated and optimised. This scenario is plausible and can be demonstrated with computer models. We think the evidence in the present study supports this scenario. Contrarily, in standard darwinian theory new genetic programs must be written originally from scratch. In our opinion, nothing in the present study even hints at such a process.

Something is missing in our understanding of how evolution produced complex creatures. I don't know what it is, nor do I think anyone else does, contrary to the claims you hear asserted, says Mark Bedau (pictured), co-organizer of the Eleventh International Conference on the Simulation and Synthesis of Living Systems. Mark has advised us in our own efforts to explore the range of evolution in closed or quarantined systems, but this admission is news to us. Bedau also remarks, Unlike the real world, the outcome of computer evolution is built into its programming.

Mark Bedau But Mark, why is this unlike the real world? In our observation, biological evolution depends on its programming in the same way. New complex features readily emerge when the genetic programming for them is installed and activated by well-studied processes including horizontal gene transfer (HGT). For evolution among prokaryotes, this understanding is already in place, but the significance of this major paradigm shift goes unnoticed. For evolution among eukaryotes, the situation reminds us of that for prokaryotes a decade ago — examples of HGT with important evolutionary effects are accumulating rapidly.

We congratulate Mark for his straightforwardness. We hope he and others will seriously consider the possibility that the outcome of biological evolution is also built into its programming.

Our results indicate that, on average, at least 81 ± 15% of the genes in each genome studied were involved in lateral gene transfer at some point in their history, even though they can be vertically inherited after acquisition, uncovering a substantial cumulative effect of lateral gene transfer on longer evolutionary time scales. This result comes from geneticists in Düsseldorf and Tel Aviv using a new method of network analysis that reveals "both vertical and lateral components of evolutionary history among 539,723 genes distributed across 181 sequenced prokaryotic genomes." In their report they comment —

  • Once acquired, genes can be vertically inherited within a group, and the MLN [minimal lateral network] suggests that this has occurred for the vast majority of genes, and probably all, given that we have inferred no LGT [lateral gene transfer] events from conflicting gene trees, during prokaryote genome evolution.
  • Our findings indicate that, over long evolutionary time scales, the cumulative role of LGT leaves almost no gene family among prokaryotes untouched.
  • The conservative lower bound nature of our method for inferring LGT among prokaryotes indicates that evolution by lateral transfer affects the vast majority of gene families, and probably all, but possibly at a low rate.
If all genes in prokaryotes have probably been acquired by LGT — also called horizontal gene transfer (HGT) — the standard darwinian explanation for where genes come from is inadequate. We are astounded by the lack of attention to this crisis.
