How Man Came to Be: Human Origins Between Evolution and Religion

What religion says about how humankind appeared

The striking resemblance between apes and humans has been explained in wildly different ways across history, with each answer more contradictory than the last. Religious and folk traditions attributed human origins to divine creation, while modern science traces humanity to a long evolutionary process shared with other primates. Both of these strands — the theological and the scientific — are worth setting out clearly, because the question of where humankind came from sits at the heart of how different cultures understand what it means to be human.

The startling similarity between apes and humans

The likeness of great apes to humans puzzled naturalists for centuries. As recently as two hundred years ago, many scholars regarded the great apes as a breed of wild "orangutans" — literally "forest people," since orangutan in Malay means "man of the forest." Orangutans live in southern Asia, on the islands of Sumatra and Borneo, and some naturalists genuinely believed the animals were only pretending to be mute and unable to understand human speech, out of fear that they might be enslaved and forced into crushing labour.

In an earlier article we have already examined the behaviour of apes.

Some books published at the start of the last century repeated tall tales about orangutans supposedly working aboard ships as sailors, and similar fables.

This is how great apes — mistaken for wild forest people — were depicted in past centuries.

How churchmen explained the resemblance of apes and humans

Churchmen approached the similarity of apes to humans quite differently. For them, to admit that great apes were people would also mean admitting that God, who made humans in his own image and likeness, must resemble an ape. Because of this, churchmen flatly rejected the idea that anthropomorphic apes were a kind of wild human.

Instead, the church fathers argued that orangutans had been people in the distant past who sinned against God and were turned into animals as punishment. Belief in this version was so strong that, according to surviving accounts, some churchmen travelled to Africa to preach the Bible among apes, hoping they might be transformed back into humans and reconciled with the almighty "creator." The notion that humankind appeared on Earth by supernatural means, fashioned by God, is a relic of a very distant past.

Did humans descend from apes? The scientific view

Modern science holds that humans and apes descend from common ancestors, and that Homo sapiens emerged through evolution rather than a single act of special creation. This is the mainstream position of biology, anthropology and palaeontology, and it is built from converging lines of evidence — fossils, genetics, comparative anatomy and archaeology — rather than from any one discovery. The account below sets out how this view developed, how it clashes with the idea of divine creation, and what it implies for the origins of religious thought itself.

Evolutionary theory versus the idea of divine creation

Evolution and special creation offer fundamentally opposed explanations for the origin of humanity. The theory associated with Charles Darwin treats humans as one branch of the primate family, shaped by natural selection over millions of years, whereas creationism holds that God fashioned people directly. Within religious thought several distinct positions have taken shape:

• Young-Earth Creationism — the belief, promoted by organisations such as Answers in Genesis, that the Earth is only thousands of years old and that humanity descends from a literal Adam and Eve, with a historical Global Flood reshaping the planet.
• Old-Earth Creationism — the acceptance of an ancient Earth while still holding that God created humans specially rather than through descent from earlier species.
• Theistic Evolution — the view that evolution is the mechanism God used to bring about life and humankind, reconciling Human Evolution with faith.

Critics of evolution raise scientific objections — gaps in the fossil record, the complexity of the eye, the origin of the genetic code — but the scientific consensus regards these as questions within evolutionary biology rather than refutations of it. The disagreement is often framed through several models of the science–religion relationship: the conflict model, where the two are seen as irreconcilable; the separation model, where each addresses non-overlapping questions (a stance associated with Stephen Jay Gould); and the interaction model, where they inform one another.

Human brain growth and the capacity for religious ideas

The expansion of the human brain created the cognitive foundations that made religious thought possible. As the neocortex enlarged and social groups grew more complex, our ancestors developed the mental machinery to imagine unseen agents, remember shared stories and reason about cause and effect. Robin Dunbar proposed that neocortex size sets a limit on the number of stable social relationships a species can maintain — Dunbar's theory — and that the demands of ever-larger groups drove both brain growth and the ritual behaviours that bind communities together.

Several cognitive prerequisites had to fall into place before humans could hold religious beliefs at all: the ability to attribute intentions to others, the capacity for symbolic thought, and language rich enough to transmit abstract concepts across generations. Tool use likely reinforced beliefs about cause and effect, encouraging early humans to seek hidden agents behind natural events. Philip Lieberman studied the evolution of the vocal tract and the emergence of speech, work that bears on how symbolic communication — and with it the sharing of spiritual ideas — became possible. Early language may have begun attributing spirit or intention to animals, weather and the dead, laying the groundwork for the supernatural.

Evolutionary psychology and the origin of religion

Evolutionary psychology treats religion as a by-product, or in some accounts an adaptation, of the evolved human mind. Researchers such as Hervey C. Peoples, Pavel Duda and Frank W. Marlowe have used phylogenetic methods — the same statistical tools used to reconstruct evolutionary trees — to trace how religious traits appeared in a sequence across human history. Their work, published in Human Nature, suggests that animism was the earliest and most fundamental religious trait, followed by belief in an afterlife, then shamanism and ancestor worship, and finally belief in high gods who police morality.

A long line of scholars proposed competing theories about religion's origins, and their premises were frequently shaped by the biases of their era:

• Edward Tylor argued that religion began as animism — the belief that spirits inhabit people, animals and objects — which he regarded as the primordial religious idea.
• R. R. Marett countered with animatism, the belief in an impersonal supernatural force pervading the world before spirits were personified.
• James Frazer, in The Golden Bough, held that magic preceded religion, with humans first trying to control nature by ritual before turning to gods.
• Sigmund Freud, in Totem and Taboo, offered a psychoanalytic account rooting religion in guilt and the dynamics of the primal family.

Behaviour that looks proto-religious has been observed in other species, complicating the idea that spirituality is uniquely human. Frans de Waal documented social intelligence, deception, empathy and rudimentary morality in chimpanzees and bonobos, while Barbara King has written on grief and mourning-like behaviour in elephants and primates. Ritual, in this view, functions as a social mechanism — building trust, reinforcing cooperation and signalling commitment within a group. The ritual/speech coevolution theory holds that reliable symbolic communication and shared ceremony evolved together, allowing early humans to trust one another and act collectively.

Because so much of this concerns behaviour and cognition that leave no direct trace, definitive answers about the ultimate origin of religion may be impossible to reach. This is one of the clear limitations of scientific investigation into the subject: the evidence is fragmentary, and reconstructing the inner mental life of ancestors who left only bones and artefacts is inherently uncertain. Science here operates under methodological naturalism — the practice of explaining phenomena through natural causes — which itself sets bounds on what such inquiry can conclude about the supernatural.

The dispersal of early humans out of Africa

Homo sapiens arose in Africa and spread across the globe from there, and the archaeological trail of that journey includes some of the earliest evidence of symbolic behaviour. As populations moved out of Africa — across a greening Sahara Desert in some periods and eventually into environments as extreme as the Arctic — they carried with them the cognitive capacities that underpin ritual and belief. The Neanderthals, a related human lineage, appear to have buried their dead, hinting at symbolic or spiritual concern.

Physical evidence of symbolic thought clusters in the Upper Paleolithic and just before it:

• Engraved red ochre and pierced shell beads from Blombos Cave and Pinnacle Point in South Africa, among the oldest known signs of symbolic expression.
• Deliberate use of pigment and personal ornamentation, which many archaeologists read as markers of shared meaning and identity.
• Cave art and burial goods that appear as human groups expanded and grew more socially complex.

The Smithsonian National Museum of Natural History, through its Human Origins Initiative and the David H. Koch Hall of Human Origins, presents this scientific understanding of human origins to the public, and its Broader Social Impacts Committee — including scholars such as Dr. Connie Bertka and Dr. Jim Miller — works on how evolutionary science and religious worldviews can engage with one another. Science writers including Nicholas Wade and biologists such as Lewis Wolpert have popularised these accounts of how belief and cognition evolved alongside our species. Some of these questions overlap with wider discussions of how science relates to life.

The many theories of human origins among the world's peoples

Peoples around the world preserved a remarkable variety of stories about the origin of humankind, reflecting the sheer diversity of religious belief across cultures. These traditions range from the oldest folk tales to the elaborate creation myths of literate civilisations, and comparing them reveals how differently societies have imagined their own beginnings.

Ancient tales: people from the Moon, from eggs, from trees

The most archaic origin stories describe humans arriving on Earth in fantastical ways. In some, the first people fell to Earth from the Moon; in others they grew on trees or hatched from an egg laid by some miraculous bird. These narratives belong to an early stratum of human imagination, before craft and metaphor drawn from making things had entered the storytelling.

Legends of humans made by gods and heroes

As crafts developed and people increasingly saw themselves as makers and creators of objects, new legends emerged in which the first humans were fashioned by heroes or gods — carved from wood, hewn from stone, and so on. The technology a society mastered shaped the metaphors it used to explain its own creation.

People made from clay: Egypt and ancient Greece

Peoples skilled at pottery arrived at the idea that the first humans were moulded by gods from clay. In ancient Egypt it was believed that a god named Khnum shaped the first human on a potter's wheel. According to a Greek legend, the god Zeus, like a potter, moulded humans from clay, while the goddess Athena "ensouled" them — that is, brought them to life.

The Greek god Zeus moulds the first humans from clay, and the goddess Athena "ensouls" them.

The diversity of religious beliefs across the world

The world's major religions each carry their own account of human origins and their own founders, revealing how varied religious worldviews truly are. Judaism, Christianity and Islam share the tradition of a single created first couple, with Muhammad as the prophet of Islam and Jesus central to Christianity. Buddhism traces its origins to the Buddha, Confucius shaped a moral and philosophical tradition in China, and Hinduism preserves cyclical accounts of creation. A sacred text — Scripture in the Abrahamic faiths — typically anchors each of these worldviews and transmits its creation account across generations.

Anthropologists often contrast the religions of contemporary hunter-gatherers with these large-scale world religions. Egalitarian foraging societies such as the !Kung tend to hold beliefs quite different from the moralising high gods of state religions, which has led some scholars to trace how belief systems changed as societies grew larger and more hierarchical. Yet using present-day "primitive" societies as direct models for prehistoric religion is problematic, because those communities have their own long histories and are not living fossils of the Stone Age. Comparative surveys such as World Religions—From Ancient History to the Present and the New Encyclopædia Britannica document just how wide this variety is.

The Bible on the origin of humankind

The Bible, the sacred book of Jews and Christians, gives an account of human origins closely paralleling the clay-creation myths of other cultures. In Genesis it teaches that God created the first humans directly and that all people descend from them — a claim that continues to shape how millions understand human nature, purpose and worth.

The legend of the creation of Adam and Eve

The biblical legend tells that God, named Yahweh or Jehovah, moulded the first man — Adam — from "red earth," that is from clay, and "breathed into him a living soul." When Adam slept, God took a rib from his body and from it created the woman, Eve. From these two first people, the Bible asserts, the entire human race descended. The story continues in the Garden of Eden, where the temptation by Satan leads to the Fall of man — the moment traditional theology treats as the entry of sin into the world.

Adam and Eve: historical figures or myth?

Whether Adam and Eve were real historical individuals or symbolic figures is a genuine dividing line within religious thought. Young-Earth Creationists and organisations like Answers in Genesis insist on a literal first couple, treating the genealogies as records of real ancestors. Many other believers, including proponents of theistic evolution, read Adam and Eve as representative or mythological figures expressing theological truths about humanity's relationship with God rather than as biological progenitors. The scientific picture of a founding human population numbering in the thousands, dispersing from Africa, sits uneasily with a literal descent from two individuals.

Biblical genealogies and chronology

Biblical genealogies are the basis on which literalist chronologies of human history are built. By adding up the ages recorded in Genesis and later books, some traditions calculate an age for humanity of only a few thousand years — the foundation of Young-Earth Creationism. Old-Earth Creationists and theistic evolutionists instead read these lists as selective or symbolic rather than as a continuous, exhaustive timeline, allowing the deep antiquity revealed by fossils and archaeology.

The descendants of Adam and Noah

The biblical narrative traces all living people back through the descendants of Adam and, after the Global Flood, through Noah and his sons. In this framework the diversity of nations is explained as the spreading out of Noah's line, a genealogical account that literalist readings map onto the peopling of the Earth — again standing in contrast to the scientific account of population dispersal from Africa.

The "Creation Mandate" and the purpose of humanity

The idea that humans bear the Image of God gives the biblical account its distinctive claim about human purpose. Being made in God's image is understood to set humanity apart and to confer dignity and moral responsibility. From this flows the Creation Mandate — the charge in Genesis for humans to fill the Earth, cultivate it and care for it, casting people as vice-regents or stewards of creation rather than merely one animal among others. This theological reading of what it means to be human stands as the religious counterpart to the evolutionary account of human capacities.

The antiquity of religion across civilisations

Religion is one of the oldest and most universal features of human civilisation, appearing in some form in virtually every society historians and archaeologists have studied. Its antiquity is precisely why reconstructing its origins is so difficult, and why scholarship on the subject has so often been coloured by the assumptions of the scholars themselves.

Bias and faulty premises in religious scholarship

Much early scholarship on the origins of religion rested on faulty premises and the prejudices of its time. Nineteenth- and early twentieth-century theorists frequently assumed that contemporary hunter-gatherer societies were "arrested" at an early stage of development and could be read as direct windows into prehistory — an assumption modern anthropology rejects. Framing some peoples as "primitive" imported a bias that distorted conclusions about how and why religion first arose, and separating genuine evidence from those inherited assumptions remains a central challenge.

The development and modification of religious systems

Religious systems are not static; they develop, split and reform continually over time. New faiths grow out of older ones, doctrines are revised, and reform movements reshape established traditions — the Protestantism launched when Martin Luther broke with Catholicism being a well-documented European example. Phylogenetic studies of cultural evolution treat religious traits much like genetic ones, tracing how beliefs branch, are inherited and are modified as they pass between generations and populations.

Church against science

For many centuries the militant church waged a bitter war against science, punishing those whose findings contradicted Scripture. Churchmen held that only what the Bible affirmed could be accepted as true, and they enforced that view with imprisonment and execution. As one of the most influential churchmen, Saint Augustine, put it:

"Only that which is confirmed by the Bible may be accepted, for its authority carries greater weight than all the powers of the human mind."

This conflict model — treating faith and inquiry as irreconcilable enemies — dominated for generations, though it is only one of several ways the relationship between science and religion has been understood.

The Inquisition and the persecution of dissenters

The church dealt cruelly with those who diverged from its views, and the Inquisition — the courts of the Catholic Church — condemned tens and even hundreds of thousands of people to dungeons and the stake for disbelief in the Bible. Under the sentences of the chief inquisitor in Spain, Torquemada (15th century), more than ten thousand people alone were burned. Among the scholars who suffered:

• The 14th-century Italian scholar Cecco d'Ascoli, who believed the Earth was spherical and that people the Bible never mentions lived on its far side, was burned as a heretic.
• Miguel Servet (15th century), who came close to discovering the circulation of blood in humans and animals, perished at the stake.
• In 1600 the great astronomer Giordano Bruno, who also taught that antipodean peoples lived "on the other side of the Earth," was burned.
• The remarkable 17th-century scholar Lucilio Vanini, who argued that everything changes and that people had not always lived as they did in his day, had his tongue cut out and was burned by sentence of the Inquisition.

A great many scholars died at the hands of "pious" fanatics in the cells and dungeons of the Inquisition, and many more were forced to kneel before the church and renounce their life's work. In his old age the church compelled Galileo (16th–17th centuries) to declare all his great achievements a "heresy."

The celebrated 16th-century physician and anatomist Andreas Vesalius, who escaped the Inquisition's fire thanks to the protection of King Philip II of Spain, was forced to abandon all further scientific work.

Even in the 18th century, the theological faculty of the University of Paris compelled the famous French naturalist Buffon to declare publicly:

"I renounce everything in my book concerning the formation of the Earth, and in general everything that may contradict the account of Moses" (Moses being the legendary author of the Bible).

These are only a few episodes from the long history of religion's struggle against science.

Conclusions: science and religion on the origin of humankind

Science and religion offer two very different but not always exclusive answers to how humankind appeared. Science, working within methodological naturalism, describes Homo sapiens as the product of evolution and dispersal from Africa, and treats religion itself as a phenomenon that evolved alongside the human mind. Religion, in the biblical tradition, describes humans as specially created in the Image of God with a distinct purpose.

Rather than a single verdict, several relationships between the two are possible — conflict, separation, or interaction — and positions such as theistic evolution and old-earth creationism show that many believers accept the scientific account while retaining faith. Given the fragmentary evidence about the deep past, definitive answers about the ultimate origin of both humanity and religion may remain out of reach, which is exactly why the question has produced such a rich variety of responses across cultures and centuries.
