J. Craig Venter, best known for being the first to sequence the human genome in 2000, is recognized as one of the leading scientists of the 21st century. Ten years after his important accomplishment, Venter was credited for successfully recreating “the first synthetic species” in 2010 – named Mycoplasma laboratorium.
In his relentless pursuit to “understand the molecular and biological function of every gene in a cell,” Venter released the latest findings discovered in his genetics research laboratory in Southern California. The paper, entitled “Design and Synthesis of a Minimal Bacterial Genome,” was published on March 25, 2016 in the journal Science. The findings have emerged as a new genomic evolution nightmare for Craig Venter.
Venter’s research team attempted whittling down the genome of a simple bacterium, Mycoplasma mycoides, for the purpose of revealing the bare-bones set of genetic instructions capable of reproducing life.
The final laboratory product is now known to have the world’s most bare-bone genome. Named syn3.0 (pictured above) , the organism contains just 473 genes. By comparison, the gram-negative bacteria Escherichia coli contains between 4,000 to 5,500 genes, while humans have roughly 20,000 and the fruit fly has roughly 26,000 genes. Biological complexity is unrelated to the number of genes.
“To me, the most interesting thing is what it tells us about what we don’t know,” said Jack Szostak, a biochemist at Harvard University who was not involved in the study in an interview with Singer. “So many genes of unknown function seem to be essential.”
While Venter’s research team originally had expected to end-up with a small fraction of genes with yet an unknown identifiable function, “we were totally surprised and shocked,” said Venter (pictured right) in an interview with Singer. “This is truly a stunning number,” he said.
Of the 473 genes studied, the function of 149, (31% of the 473) could not be determined. Venter concludes –
“The minimal cell concept appears simple at first glance but becomes more complex upon close inspection… Unexpectedly, it also contains 149 genes with unknown biological functions, suggesting the presence of undiscovered functions that are essential for life.”
When Singer asked whether modern science has sufficient knowledge of basic biological principles, Venter replied –
“The answer is a resounding no.”
Raising the question “What’s left after trimming the genetic fat,” Singer notes, “It is unclear what the remaining 149 genes do.”
Scientists can broadly classify 70 of them based on the genes’ structure, but the researchers have little idea of what precise role the genes play in the cell. The functions of the other 79 genes are a complete mystery.
“We don’t know what they provide or why they are essential for life — maybe they are doing something more subtle, something obviously not appreciated yet in biology,” Venter said. “It’s a very humbling set of experiments.”
As Singer explains, “When scientists first began searching for such a thing 20 years ago, they hoped that simply comparing the genome sequences from a bunch of different species would reveal an essential core shared by all species. But as the number of genome sequences blossomed, that essential core disappeared.”
To re-trace the molecular stepping stones of biological evolution is at the core of Venter’s interest. “We could reduce billions of years of evolution to maybe years or months or weeks,” he speculated.
“In theory, Venter added, “we should be able to add genes back to [syn3.0] to recapitulate key parts of evolution.”
Venter’s syn3.0 discovery, however, underscores why the once widely popular “one gene, one enzyme” hypothesis proposed by Nobel Prize winners George Beadle and Edward Tatum, (pictured left) )in the early Darwinism era of the twentieth century, ended as a colossal bust.
“In fact,” Singer notes, “there’s no single set of genes that all living things need in order to exist.” The shock waves of the genomic revolution that started in the late twentieth century has essentially crushed the fundamentals of Darwinism and the Modern Evolutionary Synthesis theory.
In 2010, David Ussery, a biologist at Oak Ridge National Laboratory in Tennessee, and his collaborators, compared 1,000 genomes. They found that not a single gene is shared across all of life. “There are different ways to have a core set of instructions,” Szostak suggested.
Earliest life forms, however, could not have even started with the complexity of 400 genes. “We didn’t go from nothing to a cell with 400 genes,” affirmed Szostak.
Some evolutionists contend that this type of bottom-up approach is necessary in order to truly understand life’s essence. “If we are ever to understand even the simplest living organism, we have to be able to design and synthesize one from scratch,” said Anthony Forster, a biologist at Uppsala University in Sweden. “We are still far from this goal.”
Syn3.0 is a new evolution nightmare for Craig Venter. The possibility of discovering evidence for a genetic mechanism of evolution is now even more improbable.
“The more I study science,” Albert Einstein found, “the more I believe God.” In a letter to a little girl named Phyllis, Einstein wrote –
“Everyone who is seriously involved in the pursuit of science becomes convinced that some spirit is manifest in the laws of the universe, one that is vastly superior to that of man.”
The Genesis record continues to be compatible with science evidence discovered in nature – “kind after kind.”
Evolution, once a theory in crisis, is now in crisis without even a cohesive unifying theory. Biological evolution exists only as a philosophy–not as a scientific fact.
