The history of life on Earth traces the processes by which living and fossil organisms evolved, from the earliest emergence of life to the present. Earth formed about 4. The earliest evidence of life comes from biogenic carbon signatures [2] [3] and stromatolite fossils [14] discovered in 3. In , possible "remains of biotic life " were found in 4. Microbial mats of coexisting bacteria and archaea were the dominant form of life in the early Archean Epoch and many of the major steps in early evolution are thought to have taken place in this environment.

Origins of Life I: Early Ideas and Experiments

The David H. It is in recognition of these broad factors that public engagement materials, events, and contributions to the Human Origins web site are being developed by the Broader Social Impacts Committee BSIC to support the exhibition in the David H.

Koch Hall of Human Origins. The committee recognizes the unique opportunity the subject of human origins offers for the exploration of challenging cultural topics, which in turn can inspire greater public interest in, and understanding of, science. Thus, it is with input from the committee that the co-chairs have prepared this primer.

It provides a brief introduction to issues that arise at the crossroads of science and religion, particularly in relation to the scientific accounts of evolution and human origins that are presented in the exhibit. A question and answer format is used to highlight common concerns for each of these topics. Cultural divides in the United States over the acceptance of evolution and scientific understandings of human origins make this interchange relevant.

They also offer an opportunity to inspire a positive relationship between science and religion. Visitors to the David H. Koch Hall of Human Origins bring with them many assumptions about science, about religion, and about their relationship. These assumptions may impact, positively or negatively, their willingness and ability to engage the scientific presentation of human origins. The questions below are offered as a guide to begin thinking about science and religion in the context of the possible interactions of religious worldviews with a scientific account of human evolution and origins.

Science is a way to understand nature by developing explanations for the structures, processes and history of nature that can be tested by observations in laboratories or in the field. Sometimes such observations are direct, like measuring the chemical composition of a rock. Other times these observations are indirect, like determining the presence of an exoplanet through the wobble of its host star.

An explanation of some aspect of nature that has been well supported by such observations is a theory. Well-substantiated theories are the foundations of human understanding of nature. The pursuit of such understanding is science. Religion, or more appropriately religions, are cultural phenomena comprised of social institutions, traditions of practice, literatures, sacred texts and stories, and sacred places that identify and convey an understanding of ultimate meaning.

Religions are very diverse. While it is common for religions to identify the ultimate with a deity like the western monotheisms — Judaism, Christianity, Islam or deities, not all do.

There are non-theistic religions, like Buddhism. Although science does not provide proofs, it does provide explanations. Science depends on deliberate, explicit and formal testing in the natural world of explanations for the way the world is, for the processes that led to its present state, and for its possible future. When scientists see that a proposed explanation has been well confirmed by repeated observations, it serves the scientific community as a reliable theory.

Well-supported theories guide future efforts to solve other questions about the natural world. Religions may draw upon scientific explanations of the world, in part, as a reliable way of knowing what the world is like, about which they seek to discern its ultimate meaning.

Religious understanding draws from both subjective insight and traditional authority. However, this is an erroneous judgment. Virtually all of the historic religions include traditions of rational reflection.

Science and religion both have historical traditions that exhibit development over time. Each has places for individual insight and communal discernment. Analytic and synthetic reasoning can be found exhibited in both.

Science and religion have been and continue to be formative elements shaping an increasingly global human society. Both science and religion have served to jeopardize and contribute to the common human good. Typical assumptions about this relationship fall into one of three forms: conflict, separation or interaction.

A conflict approach assumes that science and religion are competitors for cultural authority. Either science sets the standard for truth to which religion must adhere or be dismissed, or religion sets the standard to which science must conform. For example, some atheists adopt this approach and argue that science reduces religion to a merely natural phenomenon. Conversely, some religious adherents, while claiming to accept science, will identify specific points at which mainstream scientific findings must be distorted or abandoned for the sake of religious convictions.

Such an adversarial approach tends to rule out any constructive engagement between science and religion. Individuals who prefer a separation approach hold that science and religion use different languages, ask different questions and have different objects of interest e. By highlighting the differences between science and religion, conflict is avoided. While this approach allows a person to explore what science has learned about human origins without fear of conflict with religious beliefs, it also encourages that the science be left, so to speak, at the museum threshold so that it has no impact on other non-scientific explorations of what it means to be human.

A consequence of separation is that the science of human origins can be viewed as irrelevant to what might be the deepest of human concerns. It should be noted that it is true that science is practiced without reference to religion. God may be an ultimate explanation, but God is not a scientific explanation. This approach to science is called methodological naturalism. However, this method of isolating religious interests from scientific research is not an example of the separation approach.

Historically, this bracketing out of religious questions in the practice of scientific inquiry was promoted by religious thinkers in the 18th and 19th centuries as the most fruitful way to discover penultimate rather than ultimate explanations of the structures and processes of nature.

A third possibility for the relationship between science and religion, one of interaction , at minimum holds that dialogue between science and religion can be valuable, more that science and religion can constructively benefit from engagement, and at maximum envisions a convergence of scientific and religious perspectives.

Generally, this view encourages an effort to explore the significance of scientific understanding for religious understanding and vice versa.

With this approach science remains relevant beyond the museum for many people who might otherwise ignore scientific findings. The National Museum of Natural History of the Smithsonian Institution has a responsibility due to its charter to provide the public with an opportunity to explore for themselves the most recent scientific understandings of the natural world, including human origins.

People are well aware that insights from the humanities, including the arts, literature and religious traditions, have much to say on this topic as well. For some people an evolutionary account of human origins may be greeted with skepticism because it challenges their particular religious commitments. In contrast, other people find their religious perspectives are deepened and enriched by an evolutionary understanding of human origins.

Although the questions below recognize this range of perspectives, many of the questions reflect expectations that are especially characteristic of people from those religious communities that are skeptical about the science of evolution.

Ironically, people in these latter communities often value science and seek scientific support for their particular religious commitments. In this sense of the word, many creationists accept an evolutionary understanding of natural history. However, at least four types of creationism can be identified, and each has a distinctive view of the evolutionary sciences and human origins.

Human beings were created through a direct act of divine intervention in the order of nature. While many aspects of nature may be the consequence of direct acts of divine creation, at very least they hold that the very beginning of the universe, the origin of life and the origin of humankind are the consequence of distinct acts of divine intervention in the order of nature. Theistic evolutionists also hold that the sacred text provides an infallible account of why the universe, all life and humankind came into existence.

However, they also hold that for the most part, the diversity of nature from stars to planets to living organisms, including the human body, is a consequence of the divine using processes of evolution to create indirectly. Still, for many who hold this position, the very beginning of the universe, the origin of life, and the origin of what is distinctive about humankind are the consequence of direct acts of divine intervention in the order of nature.

Evolutionary theists hold that the sacred text, while giving witness to the ultimate divine source of all of nature, in no way specifies the means of creation. Further, they hold that the witness of creation itself is that the divine creates only indirectly through evolutionary processes without any intervention in the order of nature. It is intended that those Americans who do not accept evolution will experience in this exhibition an open invitation to engage the science presented, explore the supporting materials, and participate in conversation with staff and volunteers without fear of ridicule or antagonism.

Though the viewpoints of those who do not accept the scientific explanation of human origins are not affirmed in the exhibition, the personal importance of their perspectives is appreciated.

What the exhibition intends to create is an environment for an enriching and respectful dialogue on human origins that currently can be found in no other venue. Scientific theories change in the light of new discoveries. Why should we believe what science has to say today about human origins when it may change tomorrow? The perception that scientists completely change their mind with each new discovery is mistaken.

Although this has occurred occasionally in the history of science, it is relatively rare. What is frequently missed is the broad consensus among scientists in a field, like that of human origins research, which provides the basis for seeking new discoveries. For example, it is broadly agreed that the various characteristics that distinguish our species did not emerge all at once. Walking on two legs emerged before making stone tools, and both of these occurred well before the biggest increase in human brain size.

All of these came before the origin of art and symbolic communication. Farming and the rise of civilizations occurred much later still.

There is broad scientific agreement even in the light of the most recent fossil discoveries that these changes that define our species took place over a period of about 6 million years.

Each visitor to the exhibition has the opportunity to explore both the latest findings of laboratory and field research as well as consider how the scientific community is using these to give a more complete account of human origins. Each visitor is also invited to consider how this account might inform their deepest religious understanding of what it means to be human. Advocates of Intelligent Design ID hold that there are features of the natural world for which there are no natural explanations and that these features can be shown analytically to be the result of a designing agent.

Although ID advocates seldom specify who the designer is, the logic of their argument requires that the designer be beyond nature, or supernatural. However, advocates for ID have not been able to show that their claims are genuinely scientific. While the scientific community welcomes new theoretical proposals, these must lead to active research programs that deepen our understanding of nature and that can find confirmation in either laboratory or field observations.

Thus far, ID advocates have been unable to do either. As an institution of informal public education, the exhibit cannot advocate a religious position. Dover Area School District, For all of these reasons it is inappropriate for ID to be included in a scientific presentation on human origins. Still, some people believe that there is a scientific debate about evolution, and that advocates of ID represent one side of this debate.

As noted above, the scientific community does not recognize ID as a scientific position. Therefore, it is not one side of a scientific debate. At the same time, the exhibition does provide the visitor with genuine examples of how the evidence for human evolution is interpreted differently by different researchers, for example, in the construction of frameworks for understanding how prehistoric species are related to one another.

Here different interpretations of the evolutionary data are presented. While there is lively debate about such alternatives and data is actively sought to discriminate between them, there is no scientific debate about the basic validity of the theory of evolution as the best scientific explanation for the expansion and diversification of life on Earth, including human life.

Does the exhibition identify the gaps in the scientific understanding of the origin of humans, gaps that can suggest that God played a role?

Despite significant theoretical progress, experimental anomalies, paradoxes, and enigmas have revealed paradigmatic limitations. Thus, the advancement of scientific understanding requires new models that resolve fundamental problems.

If a species can develop only from a preexisting species, then how did life originate? Among the many philosophical and religious ideas advanced to answer that question, one of the most popular was the theory of spontaneous generation, according to which, as already mentioned, living organisms could originate from nonliving matter. With the increasing tempo of discovery during the 17th and 18th centuries, however, investigators began to examine more critically the Greek belief that flies and other small animals arose from the mud at the bottom of streams and ponds by spontaneous generation. The Italian physician and poet Francesco Redi was one of the first to question the spontaneous origin of living things. Having observed the development of maggots and flies on decaying meat, Redi in devised a number of experiments, all pointing to the same conclusion: if flies are excluded from rotten meat, maggots do not develop. On meat exposed to air , however, eggs laid by flies develop into maggots. Nonetheless, in support for spontaneous generation was renewed with the publication of An Account of Some New Microscopical Discoveries by the English naturalist and Roman Catholic divine John Turberville Needham.

Metrics details. The common thread of evolution runs through all science disciplines, and the concept of evolution enables students to better understand the nature of the universe and our origins. The course examines basic principles and methods of science by following the concept of evolution from the big bang to the origin and evolution of life. Case studies of leading scientists illustrate how their ideas developed and contributed to the evolution of our understanding of the world. Evidences for physical, chemical, and biological evolution are explored, and students learn to view the evolution of matter and of ideas as a natural process of change over space and time.

The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in , is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring. Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology. More simply put, the theory can be described as "descent with modification," said Briana Pobiner, an anthropologist and educator at the Smithsonian Institution National Museum of Natural History in Washington, D.
