“This is a timeline of dominant life-forms on earth,” Edmond said, “presented in terms of species population, food-chain position, interspecific supremacy, and overall influence on the planet. Essentially, it is a visual representation of who’s running the show on earth at any given time.”

Langdon’s eye traced along the diagram as different bubbles expanded and contracted, indicating how various large populations of species had appeared, proliferated, and disappeared from existence.

“The dawn of Homo sapiens,” Edmond said, “occurs at 200,000 BC, but we were not influential enough to appear in this graph until about sixty-five thousand years ago, when we invented the bow and arrow and became more efficient predators.”

Langdon scanned ahead to the 65,000 BC mark, where a thin blue bubble appeared, marking Homo sapiens. The bubble expanded very slowly, almost imperceptibly, until around 1000 BC, when it quickly got thicker, and then seemed to expand exponentially.

By the time his eye reached the far right of the diagram, the blue bubble had swollen to occupy nearly the entire width of the screen.

Modern-day humans, Langdon thought. By far, the most dominant and influential species on earth.

“Not surprisingly,” Edmond said, “in the year 2000, when this graph ends, humans are depicted as the prevailing species on the planet. Nothing even comes close to us.” He paused. “However, you can see traces of a new bubble appearing … here.”

The graphic zoomed in to show a tiny black shape starting to form above the swollen blue bubble of humanity.

“A new species has already entered the picture,” Edmond said. Langdon saw the black blob, but it looked insignificant in comparison to the blue bubble—a tiny remora on the back of a blue whale.

“I realize,” Edmond said, “that this newcomer looks trivial, but if we move forward in time from 2000 to the present day, you will see that our newcomer is here already, and it has been quietly growing.”

The diagram expanded until it reached the current date, and Langdon felt his chest tighten. The black bubble had expanded enormously over the past two decades. Now it claimed more than a quarter of the screen, jostling with Homo sapiens for influence and dominance.

“What is that?!” Ambra exclaimed in a worried half whisper. Langdon answered, “I have no idea … some kind of dormant virus?” His mind ran through a list of aggressive viruses that had savaged various regions of the world, but Langdon could not imagine a species growing this fast on earth without being noticed. A bacterium from space?

“This new species is insidious,” Edmond said. “It propagates exponentially. It expands its territory continuously. And most importantly, it evolves … much faster than humans do.” Edmond stared into the camera again, his expression deadly serious. “Unfortunately, if I let this simulation roll ahead to show us the future, even just a few decades from now, this is what it reveals.”

The diagram expanded again, now displaying the timeline up until 2050.

Langdon jumped to his feet, staring in disbelief.

“My God,” Ambra whispered, covering her mouth in horror.

The diagram clearly showed the menacing black bubble expanding at a staggering rate, and then, by the year 2050, entirely swallowing up the light blue bubble of humanity.

“I’m sorry to have to show you this,” Edmond said, “but in every model I ran, the same thing happened. The human species evolved to our current point in history, and then, very abruptly, a new species materialized, and erased us from the earth.”

Langdon stood before the horrific graphic, trying to remind himself that it was just a computer model. Images like this, he knew, had the power to affect humans on a visceral level that raw data could not, and Edmond’s diagram had an air of finality to it—as if human extinction were already a fait accompli.

“My friends,” Edmond said, his tone somber enough to be warning of an imminent asteroid collision. “Our species is on the brink of extinction. I have spent my life making predictions, and in this case, I’ve analyzed the data at every level. I can tell you with a very high degree of certainty that the human race as we know it will not be here fifty years from now.”

Langdon’s initial shock now gave way to disbelief—and anger—at his friend. What are you doing, Edmond?! This is irresponsible! You built a computer model—a thousand things could be wrong with your data. People respect and believe you … you’re going to create mass hysteria.

“And one more thing,” Edmond said, his mood darkening even further. “If you look carefully at the simulation, you will see that this new species does not entirely erase us. More accurately … it absorbs us.”

CHAPTER 96

THE SPECIES ABSORBS us?

In stunned silence, Langdon tried to imagine what Edmond meant by these words; the phrase conjured terrifying images of the Alien science-fiction movies, in which humans were used as living incubators for a dominant species.

On his feet now, Langdon glanced back at Ambra, who was huddled on the couch, clutching her knees, her keen eyes analyzing the illustration on the screen. Langdon strained to imagine any other interpretation of the data; the conclusion seemed inevitable.

According to Edmond’s simulation, the human race would be swallowed up by a new species over the course of the next few decades. And even more frightening, this new species was already living on earth, quietly growing.

“Obviously,” Edmond said, “I could not go public with this information until I could identify this new species. So I delved into the data. After countless simulations, I was able to pinpoint the mysterious newcomer.”
