The Third Chimpanzee: The Evolution and Future of the Human Animal is a 1991 book by academic and popular science author Jared Diamond, in which the author explores concepts relating to the animal origins of human behavior. The book follows a series of articles published by Diamond, a physiologist, examining the evidence and its interpretation in earlier treatments of the related species, including cultural characteristics or features often regarded as particularly unique to humans. The book was released in the United Kingdom in 1991 by Radius under the title The Rise and Fall of the Third Chimpanzee: How Our Animal Heritage Affects the Way We Live and in the United States in 1992 by HarperCollins under the title The Third Chimpanzee: The Evolution and Future of the Human Animal. In 2014, Diamond published an adapted version for young people with Seven Stories Press titled, The Third Chimpanzee for Young People.[1]
Diamond explores the question of how Homo sapiens came to dominate its closest relatives, such as chimpanzees, and why one group of humans (Eurasians) came to dominate others (indigenous peoples of the Americas, for example). In answering these questions, Diamond (a professor in the fields of physiology and geography) applies a variety of biological and anthropological arguments to reject traditional hegemonic views that the dominant peoples came from "superior" genetic stock and argues instead that those peoples who came to dominate others did so because of advantages found in their local environment which allowed them to develop larger populations, wider immunities to disease, and superior technologies for agriculture and warfare.
The Third Chimpanzee also examines how asymmetry in male and female mating behaviour is resolved through differing social structures across cultures, and how first contact between unequal civilizations almost always results in genocide. The book ends by noting that technological progress may cause environmental degradation on a scale leading to extinction.
Organization and summary
Despite the broad canvas, the book manages to link together a coherent argument, much of which was novel at the time of publication. Borrowing insights from fields ranging from the humanities (history, linguistics, anthropology), to evolutionary biology, The Third Chimpanzee compiles a portrait of humanity's success and also its potential for disaster.
The book is divided into five parts. Part one deals with the similarity between humans and chimpanzees.
The title of the book refers to how similar taxonomically chimps and humans are, as their genes differ by just 1.6%, whereas chimps and gorillas differ by 2.3% (p.19). Thus the chimp's closest relatives are not the other apes with which it is classed, but the human (see Homininae). In fact, the chimpanzee-human difference is smaller than some within-species distances: e.g. even closely related birds such as the red-eyed and white-eyed vireos differ by 2.9%. Going by genetic differences, humans should be treated as a third species of chimpanzee (after the common chimpanzee and the bonobo).[2] Or possibly the chimpanzee's scientific name should be Homo troglodytes instead of Pan troglodytes. Diamond observes in his book that this would provide food for thought to people passing this side of the bars of a cage with the label Homo.
Sexual selection (parts two and three)
Part two considers sexual dimorphism in mammals, and particularly humans, and the mechanics of sexual selection. It considers how across species, females are more careful in selecting their mates than males (they invest far more energy into each offspring). This determines much of human behaviour: how we pick our mates, and how we organize society and child nurturing systems, leading to differing social structures in cultures such as Papua New Guinea, Kerala, and the Christian West. It also considers questions of longevity – the previous generation dies because its biological clock shuts down metabolism and repair as to divert investment from the parent individual to that of the offspring.
Part three extends the effects of sexual selection into language, art, hunting and agriculture, through the idea of honest signaling – sexual signals that also cost the signer. This is extrapolated to explain the appeal of drugs. Finally, the possibility of contact with extraterrestrial intelligence is discussed (Diamond thinks that would be a disaster).
World conquest (part four)
Part four considers conquest. Why is it that the Eurasians came to dominate other cultures? Diamond's answer is that, in part, this was due to the East–West layout of the Eurasian continent, due to which successful agricultural and animal domestication packages (combinations of certain domesticated plants and animals) could easily be adopted in regions farther east or west. On the other hand, extension of domestication packages along the North–South axis – as required in the case of the American and African continents – was much more difficult owing to severe imbalances of climate. Also, long-lasting contact with domesticated animals of agricultural populations permits greater resistance to disease, which is another reason why contact among geographically separated cultures – mostly agricultural versus hunter-gatherer societies – often leads to extinction of the latter through devastating infections.
The process of first contact between differing civilizations is examined through the descriptions of Papua New Guinea highlanders, who were first visited half a century back. Historically, Diamond argues such contacts between widely differing populations have very frequently culminated in the extinction of the disadvantaged groups like many Native American tribes, the Tasmanians, etc. There is a long list of genocides in history.[3]
Here the argument is that civilizations sometimes get caught up in internal superiority contests, and deplete the environment to such an extent that they may never recover. Examples include Easter Island and the ruins of Petra, both of which were the result of deforestation resulting in desertification, according to Diamond.
A contemporary review of the work by Frans de Waal was published by the New York Times (March, 1992), who praises the wit and breadth of the author's approach to the subject matter. He notes there is an emphasis on linguistic diversity by the author, and endorses the virtue of his inclusion and comparison of historic or far-fetched speculation on origins in hominids.[2]
Ardipithecus is a genus of an extinct hominine that lived during the Late Miocene and Early Pliocene epochs in the Afar Depression, Ethiopia. Originally described as one of the earliest ancestors of humans after they diverged from the chimpanzees, the relation of this genus to human ancestors and whether it is a hominin is now a matter of debate. Two fossil species are described in the literature: A. ramidus, which lived about 4.4 million years ago during the early Pliocene, and A. kadabba, dated to approximately 5.6 million years ago. Initial behavioral analysis indicated that Ardipithecus could be very similar to chimpanzees, however more recent analysis based on canine size and lack of canine sexual dimorphism indicates that Ardipithecus was characterised by reduced aggression, and that they more closely resemble bonobos.
The chimpanzee, also simply known as the chimp, is a species of great ape native to the forests and savannahs of tropical Africa. It has four confirmed subspecies and a fifth proposed one. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is thus humans' closest living relative.
Homininae, is a subfamily of the family Hominidae (hominids). This subfamily includes two tribes, Hominini and Gorillini, both having extant species as well as extinct species.
The bonobo, also historically called the pygmy chimpanzee, is an endangered great ape and one of the two species making up the genus Pan. While bonobos are, today, recognized as a distinct species in their own right, they were initially thought to be a subspecies of Pan troglodytes, due to the physical similarities between the two species. Taxonomically, members of the chimpanzee/bonobo subtribe Panina—composed entirely by the genus Pan—are collectively termed panins.
The genus Pan consists of two extant species: the chimpanzee and the bonobo. Taxonomically, these two ape species are collectively termed panins. The two species were formerly collectively called "chimpanzees" or "chimps"; if bonobos were recognized as a separate group at all, they were referred to as "pygmy" or "gracile chimpanzees". Together with humans, gorillas, and orangutans they are part of the family Hominidae. Native to sub-Saharan Africa, chimpanzees and bonobos are currently both found in the Congo jungle, while only the chimpanzee is also found further north in West Africa. Both species are listed as endangered on the IUCN Red List of Threatened Species, and in 2017 the Convention on Migratory Species selected the chimpanzee for special protection.
Jared Mason Diamond is an American scientist, historian, and author. In 1985 he received a MacArthur Genius Grant, and he has written hundreds of scientific and popular articles and books. His best known is Guns, Germs, and Steel (1997), which received multiple awards including the 1998 Pulitzer Prize for general non-fiction. In 2005, Diamond was ranked ninth on a poll by Prospect and Foreign Policy of the world's top 100 public intellectuals.
Guns, Germs, and Steel: The Fates of Human Societies is a 1997 transdisciplinary non-fiction book by the American author Jared Diamond. The book attempts to explain why Eurasian and North African civilizations have survived and conquered others, while arguing against the idea that Eurasian hegemony is due to any form of Eurasian intellectual, moral, or inherent genetic superiority. Diamond argues that the gaps in power and technology between human societies originate primarily in environmental differences, which are amplified by various positive feedback loops. When cultural or genetic differences have favored Eurasians, he asserts that these advantages occurred because of the influence of geography on societies and cultures and were not inherent in the Eurasian genomes.
Great ape personhood is a movement to extend personhood and some legal protections to the non-human members of the great ape family: bonobos, chimpanzees, gorillas, and orangutans.
Apes are a clade of Old World simians native to sub-Saharan Africa and Southeast Asia, which together with its sister group Cercopithecidae form the catarrhine clade, cladistically making them monkeys. Apes do not have tails due to a mutation of the TBXT gene. In traditional and non-scientific use, the term ape can include tailless primates taxonomically considered Cercopithecidae, and is thus not equivalent to the scientific taxon Hominoidea. There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes.
Great ape language research historically involved attempts to teach chimpanzees, bonobos, gorillas and orangutans to communicate using imitative human speech, sign language, physical tokens and computerized lexigrams. These studies were controversial, with debate focused on the definition of language, the welfare of test subjects, and the anthropocentric nature of this line of inquiry.
The Uplift Universe is a fictional universe created by American science fiction writer David Brin. A central feature in this universe is the process of biological uplift.
The history of Eurasia is the collective history of a continental area with several distinct peripheral coastal regions: Southwest Asia, South Asia, East Asia, Southeast Asia, and Western Europe, linked by the interior mass of the Eurasian steppe of Central Asia and Eastern Europe. Perhaps beginning with the Steppe Route trade, the early Silk Road, the Eurasian view of history seeks establishing genetic, cultural, and linguistic links between Eurasian cultures of antiquity. Much interest in this area lies with the presumed origin of the speakers of the Proto-Indo-European language and chariot warfare in Central Eurasia.
The humanzee is a hypothetical hybrid of chimpanzee and human, thus a form of human–animal hybrid. Serious attempts to create such a hybrid were made by Soviet biologist Ilya Ivanovich Ivanov in the 1920s, and possibly by researchers in China in the 1960s, though neither succeeded.
The Hominini (hominins) form a taxonomic tribe of the subfamily Homininae (hominines). They comprise two extant genera: Homo (humans) and Pan, but in standard usage exclude the genus Gorilla (gorillas), which is grouped separately within subfamily Homininae.
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological, medical, historical and forensic implications and applications. Genetic data can provide important insights into human evolution.
Demonic Males: Apes and the Origins of Human Violence is a 1996 book by Richard Wrangham and Dale Peterson examining the evolutionary factors leading to human male violence.
Self-domestication is a scientific hypothesis that suggests that, similar to domesticated animals, there has been a process of artificial selection among members of the human species conducted by humans themselves. In this way, during the process of hominization, a preference for individuals with collaborative and social behaviors would have been shown to optimize the benefit of the entire group: docility, language, and emotional intelligence would have been enhanced during this process of artificial selection. The hypothesis is raised that this is what differentiated Homo sapiens from Homo neanderthalensis and Homo erectus.
The Hominidae, whose members are known as the great apes or hominids, are a taxonomic family of primates that includes eight extant species in four genera: Pongo ; Gorilla ; Pan ; and Homo, of which only modern humans remain.
Primate cognition is the study of the intellectual and behavioral skills of non-human primates, particularly in the fields of psychology, behavioral biology, primatology, and anthropology.
Humankind: A Hopeful History is a 2019 non-fiction book by Dutch historian Rutger Bregman. It was published by Bloomsbury in May 2021. It argues that people are decent at heart and proposes a new worldview based on the corollaries of this optimistic view of human beings. It argues against ideas of humankind's essential egotism and malevolence. The book engages in a multi-disciplinary study of historical events, an examination of scientific studies, and philosophical argumentation in order to advance Bregman's opinion that, this outlook is more realistic compared to its negative counterpart. It has been translated into over 30 languages. In the United States, the paperback release was a New York Times Best Seller.
