Setting
In
 the Uplift universe an intergalactic civilization called the Five 
Galaxies, comprising a multitude of sapient races, has existed for 
billions of years. This civilization is perpetuated by the act of "uplift", in which a "patron" species genetically modifies a pre-sapient "client" species until it is sapient. The client species is typically indentured
 to its patron species for 100,000 years. A patron species gains 
considerable status, and patrons and clients often unite into powerful clans. Patron status can be lost due to extermination, or gross crimes against the galactic civilization. 
It is generally accepted in this universe that the process of 
uplift was initiated at least one billion years ago by a species known 
only as the Progenitors. Humanity
 is therefore an anomaly – a species with no apparent patron race. 
Whether humanity truly evolved independently, or whether it was 
criminally abandoned by an unknown patron early in its uplift, is a 
topic of fierce debate. Most of humanity believes itself to be a 
"wolfling" species that emerged into sapience solely through natural evolution,
 without genetic manipulation by a patron species. This belief is 
considered heresy and ridiculous by most of the galactic civilization 
and has made most of the galactic powers enemies of EarthClan. The fact 
that humanity had already uplifted two species (chimpanzees and bottlenose dolphins)
 when it encountered the galactic civilization gave humanity patron 
status, which is one of the few lucky turns it has had in its difficult 
position as pariah in the galactic civilization. This saved humanity 
from the likely fate of becoming client to another race through forced 
adoption or being punitively exterminated for the environmental damage 
done to the Earth and its native species. 
Humanity and its clients are collectively known as EarthClan. 
Humanity in the Uplift universe is not a dominant nor a technologically 
advanced species – it is centuries, even millennia, behind the great 
galactic powers and has several enemies capable of exterminating it 
entirely.
The civilization of the Five Galaxies has several "Institutes", which are bureaucracies
 that specify how species deal with each other and the uplift process. 
One of the most significant of these is the Library Institute, the 
repository of all knowledge. Humanity prides itself on using the Library
 as little as possible. For instance, instead of drawing upon the highly
 refined starship designs available in the Library, humanity tends to 
develop its own (generally vastly inferior) vessels. Humans feel that 
this is a way to exercise their own independence and creativity, and it 
occasionally allows them to find solutions to problems which have in 
fact surprised more powerful races.
The Institute of Migration determines what planets can be 
colonized and under what environmental restrictions, primarily to ensure
 that suitable races can still evolve for later uplift. The Institute 
also ensures the separation of the hydrogen-breathing and 
oxygen-breathing orders of sapient life. Other intergalactic institutes 
regulate the uplift of sapient species, navigation, warfare, etc. 
Bureaucrats are recruited from all races but are expected to put the 
interests of their bureau before that of their race and maintain strict 
neutrality; however, this does not always happen.
The civilization of the Five Galaxies is made up solely of oxygen-breathing
 species. This civilization is aware of, but by tradition rarely if ever
 interacts with, the other orders of sapient life, which include those 
which are hydrogen-breathing, transcendent, mechanical, memetic, and quantum. There is also a special designation for hypothetical orders of life which could also exist but have not been discovered. 
Technology
Unlike
 most other races, humans and their clients regard creativity as very 
desirable – the others take the view that everything useful has already 
been discovered, so it would be more efficient to search the Galactic 
Library for whatever they need. EarthClan are also considered odd for 
using archaic technology in addition to the more advanced Galactic 
technology, or sometimes preferring primitive technologies that they 
understand to more advanced ones that they don't yet understand. Most 
notably, EarthClan utilizes calculus, which is unknown and mistrusted by galactic society. All other races simply apply brute-force, finite-element analysis to any problem due to their ability to apply as much computing power as may be needed to model all phenomena.
Social behavior
Most Galactic "clans" are rather feudal and sometimes exploitative, and place strong emphasis on etiquette
 and especially on deferential behavior by members of "subordinate" 
races towards members of "superior" races. Hence they often regard 
EarthClan's informal speech as insulting and the humans' egalitarian 
treatment of their Neo-Chimp and Neo-Dolphin clients as foolish, if not 
outright offensive.
Languages
Most of EarthClan speaks Anglic. Galactics have several specialized languages:
- Gal One: Purely mathematical and similar to Morse code. Extremely slow.
- Gal Two: Bridging language.
- Gal Three: Squeaks and honks. Favored by the Gubru.
- Gal Four: Sonar based.
- Gal Five: Grunts and growls. Used by the T'4Lek.
- Gal Six: Hisses. Synthians and Thennanins.
- Gal Seven: Tone language. Tymbrimi.
- Gal Eight: Hoots and honks. Jophur and Rosh.
- Gal Nine: Chiming, syncopated. Kanten, Linten, Siqul.
- Gal Ten: Fluting, sonar-like. Brothers of the Night.
- Gal Eleven: Bridging language. Cautious, often redundant. Used between different Orders of life.
- Gal Twelve: Throaty, used by the Soro. 2 billion years old.
Planets
The following planets feature in the books, from the many thousands of inhabited planets in the setting:
- Calafia: A water-world inhabited by humans and Neo-Dolphins, currently occupied by the Soro. The name may refer to Calafia, a mythical Black Amazon.
- Cathrhennlin: A Tymbrimi university world.
- Deemi: A world leased to humans on the condition that they run the Galactic prison located there. It is bathed in ultraviolet radiation. Most of its biosphere is aquatic.
- Garth: The main setting of the novel The Uplift War, which depicts its invasion by the Gubru. The planet was leased to EarthClan after its ecology was devastated by the Bururalli species, and is inhabited by humans and Neo-Chimpanzees. Its star is called Gimelhai, and its main city is Port Helenia.
- Horst: A disaster world, assigned to Humanity less than six generations before the Streaker crisis, and populated by primitivists.
- Jijo: The main setting of the novels Brightness Reef, Infinity's Shore, and Heaven's Reach. It is a planet orbiting a carbon star in Galaxy 4, illegally inhabited by refugees from ten species: humans, chimpanzees, dolphins, Hoon, G'Kek, Urs, Traeki, Glavers, Qheuen, and Tytlal. It is also used as a refuge by the EarthClan starship Streaker. Brin uses the mix of species to explore commonalities of the sapient experience; for example Hoon Alvin Hph-Wayuo is a humicker, an enthusiast and imitator of human culture.[6]
- Jophekka: The homeworld of the Jophur, sapient and ambitious sap ring stacks.
- Juthtath: A Tymbrimi world.
- Kazzkark: Minor planet, where an important base of the Navigation Institute gathers data from E-Space.
- Kithrup: The main setting of the novel Startide Rising, where the EarthClan starship Streaker takes refuge from its many pursuers. It is a metal-rich, watery world orbiting the star Kthsemenee. It is inhabited by the pre-sapient Kiqui, and serves as the recuperation home for the psionic Karrank%.
- NuDawn: A pre-Contact colony (whose name may be a pun with Aurora - New Dawn) where an incident with Hoon inspectors brought Jophur to massacre the human colonists.
- Oakka: A "green-green" world, where the air is difficult to breathe. There was a Library branch there, but its inhabitants were corrupted and attacked the Streaker in an attempt to capture it.
- Omnivarium: A world inhabited by birds that mimic any sound, a fact discovered when the birds started mimicking the sounds of explorers performing coitus.
- Tanith: The location of the nearest full Galactic Library branch near Terra.
- Urchachka: A very dry planet, homeworld of the Urs.
Alien species and humans
EarthClan
EarthClan is the name of humanity and their clients (an animal or plant species being uplifted) in David Brin's Uplift Universe. They are named for their combined homeworld Earth. 
In the books, humanity is an insignificant race, having no known 
Patrons (a species responsible for uplifting them) and having mostly 
primitive technology. Humans have two (confirmed) clients and are 
referred to formally as "a-Human ul-Chimpanzee ul-Dolphin". However, in 
being Patrons, humanity has unknowingly protected itself from being 
forced into becoming a client of an older race. 
Humans
Humans in
 the Uplift universe are surprisingly baseline. Advanced augmentative 
technologies exist, but appear to be too expensive or socially frowned 
upon to be in widespread use. So, while cybernetics, advanced genetic 
engineering, and other technology capable of creating trans-humans exists, they are not in widespread use, as very few characters are portrayed using such technologies.
Neo-Chimpanzees
Chimpanzees
 are the first clients of humans and are the most "complete" in that 
they are closest to full sapiency. They are Stage 2 clients but almost 
became Stage 3 when the Gubru invaded Garth. Neo-Chimpanzees like music, specifically percussion.
 They are embarrassed by situations which remind them of their earlier 
status as "smart animals", especially about nudity, tree-climbing and 
above all losing their ability to speak when under stress.
Neo-Dolphins
Dolphins
 are the second clients of humans, and are some of the best pilots in 
the Five Galaxies because their aquatic origins give them excellent 
instincts for 3-D maneuvers. They are also important in planetary 
warfare because most Galactics are unaware of the strategic potential of
 the sea. Neo-Dolphins are Stage-2 Clients, and recently got their own starship, Streaker (Streaker's discoveries later caused controversy among the oxygen-breathing
 sapient species). Neo-Dolphins are at a relatively early stage of 
uplift, and this has several consequences which are important in the 
plots of the stories: the optimal genetic mix for Neo-Dolphins has not 
yet been determined, and some of the newer genetic mixes become 
dangerous to colleagues when under stress; there are significant 
differences between older and younger Neo-Dolphins, in particular older 
individuals find it more difficult to speak; and they have to struggle 
against tendencies to slip into atavistic behaviours such as the "Whale 
Dream" and rescue fever (which leads them to beach themselves).
Neo-Gorillas
Neo-Gorillas
 were at a very early stage of uplift when the Galactic Uplift Institute
 ordered humans to halt the process, because they were concerned that 
humans could not manage so many uplift projects at the same time. Some 
humans secretly continued the project on the small colony-world of 
Garth. Neo-Gorillas have some understanding that they are being 
uplifted, and chose the Thennanin as their "patrons" at a ceremony on 
Garth. This is politically very important, as the conservative and conscientious
 Thennanin are a major military power and the Neo-Gorillas' choice 
converts the Thennanin from enemies to allies of EarthClan. After 
adoption by the Thennanin, the Neo-Gorillas are termed "Garthlings."
Neo-Dogs
Dogs have been mentioned as a possible client of humanity in several books, but their final adoption has not been confirmed. 
Other clans (of aliens)
The Jophur
The
 Jophur are a fictional extraterrestrial race in the Uplift Universe. 
Physically, they are a stack of waxy, living rings.  Each ring serves a 
different purpose, and they connect to each other to form a single being
 by chemical means via an electrically conductive, sap-like substance 
that flows down the center to bind the stack together. A "master ring" 
provides a strong sense of individuality to each stack and enforces this
 with corrective electrical shocks to non-compliant rings.
The Jophur were originally the traeki, intelligent but 
often indecisive because of internal debates between the rings that 
formed each individual. Their patrons, the Poa, asked the Oallie
 to engineer the traeki further to increase their effectiveness. The 
Oailie created "master rings", shiny black rings (often described as 
"silvery") that created a strong sense of self-identity. The newly 
invigorated Jophur, as the traeki with the new master rings were called,
 quickly became a strong, vigorous force in the Five Galaxies.
According to various books in the series, most prominently the trilogy that followed the characters of Startide Rising, the Jophur quickly began a genocide
 and eradicated all but a small group of the original traeki, with the 
exception of a small "Sooner" group that settled on the planet Jijo in 
the fourth galaxy. "Sooner"
 is a term from United States history, and is used in the Uplift stories
 to describe illegal settlers on worlds that have been declared fallow,
 i.e. to be left uncolonized so that native intelligences may have a 
chance to develop naturally. The Jophur became fanatical adherents of 
one of the galaxy's religious ideologies,
 and exterminated many races they regarded as "heretics" – including the
 g'Kek, which also survived only as a "Sooner" group on Jijo.
Kiqui
Kiqui are a pre-sapient amphibious species first discovered on the planet Kithrup by Streaker's crew, who persuade them to be uplifted as clients of the humans. If this goes ahead, the Kiqui would become humanity's first extraterrestrial clients.
Plot outline and major themes
Ecology and stewardship of genetic diversity are major themes in the Uplift books. Religious orthodoxy and the behavior of static societies are also themes.
The first book in the Uplift series, Sundiver (1980), is essentially a detective story
 and occurs only decades after humanity's first contact with the Five 
Galaxies. In this story mankind discovers the sun's inhabitants and a 
plot to overthrow a patron race. This is the only novel to directly 
involve Earth. 
The second book, Startide Rising (1983), occurs centuries later. It follows the Earthclan amphibious spaceship Streaker (crewed by uplifted dolphins and their human patrons) which has discovered a colossal derelict fleet. Streaker is pursued as rumors spread throughout the Five Galaxies that the ship has found the remains of the Progenitors. 
The third book, The Uplift War (1987), occurs around the same time as Startide Rising but in another part of the galaxy. An intergalactic war, sparked by the events of Startide Rising, results in a successful invasion of the EarthClan colony on the planet Garth, heavily populated by uplifted chimps. 
In 1995 Brightness Reef was published, the first book in a
 new Uplift trilogy. The "Uplift Storm" trilogy (excluding the first 
book, which solely focuses on Jijo) follows the survivors of the 
spaceship Streaker as they continue to evade the various galactic powers. Along the way they encounter a hidden planet
 which has been inhabited by six races which have illegally settled and 
dropped out of the civilization of the Five Galaxies. They eventually 
make contact with the other orders of life. The second and third books 
in the new Uplift trilogy are Infinity's Shore and Heaven's Reach.
In Heaven's Reach, the series sums up with conclusions on 
the nature of life in the universe and revelations on the motivations of
 the oldest species in the Five Galaxies. Further explanations are 
provided on the Streaker's
 continuing mission, Earth's fate after invasion, and the nature of 
galactic life in the overlapping conspiracies of galactic civilization. 
The short story "Aficionado" or "Life in the Extreme" is set 
earliest of all the currently written work and gives an account of the 
early days of the human uplift program before Contact. The contents of 
this story have since been reused as part of the unrelated novel Existence, making its position in the uplift universe uncertain.
The novella Temptation was set just after the ending of Heaven's Reach, and tells what happened to some of the characters from the trilogy after the main story ended.
