Darwin's Radio is a 1999 science fiction novel by Greg Bear. It won the Nebula Award in 2000 for Best Novel and the 2000 Endeavour Award. It was also nominated for the Hugo Award, Locus and Campbell Awards the same year.

It was followed by a sequel, Darwin's Children, in 2003.

Plot summary

In the novel, a new form of endogenous retrovirus has emerged, SHEVA. It controls human evolution by rapidly evolving the next generation while in the womb, leading to speciation.

The novel follows several characters as the "plague" is discovered as well as the panicked reaction of the public and the U.S. government to the disease.

Built into the human genome are non-coding sequences of DNA called introns. In Darwin's Radio, certain portions of these "non-sense" sequences, remnants of prehistoric retroviruses, have been activated and are translating numerous LPCs (large protein complexes). The activation of SHEVA and its consequential sudden speciation was postulated to be either controlled by a complex genetic network that perceives a need for modification or a human adaptive response to overcrowding. The disease, or rather, gene activation, is passed on laterally from male to female as per an STD. If impregnated, a woman in her first trimester who has contracted SHEVA will miscarry a deformed female fetus made of little more than two ovaries. This "first stage fetus" leaves behind a fertilized egg with fifty-two chromosomes rather than the typical forty-six characteristic of Homo sapiens sapiens.

Charles Robert Darwin, FRS FRGS FLS FZS (/ˈdɑːrwɪn/; 12 February 1809 – 19 April 1882) was an English naturalist and geologist, best known for his contributions to evolutionary theory. He established that all species of life have descended over time from common ancestors, and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s, the scientific community and much of the general public had accepted evolution as a fact. However, many favoured competing explanations and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. In modified form, Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.
