  • Evolution, Part 1

    Environment A combination of self-interest, a regard for the wellbeing of others, and appropriate institutions can yield desirable social outcomes when people interact Game theory is a way of understanding how people interact based on the constraints that limit their actions, their motives, and their beliefs about what others will do. Experiments and other evidence show that self-interest, a concern for others, and a preference for fairness are all important motives that explain how people interact.

  • HS-LS4 Biological Evolution: Unity And Diversity

    In most interactions there is some conflict of interest between people, but also some opportunity for mutual gain. The pursuit of self-interest can sometimes lead to results that are considered good by all participants, or outcomes that none of the participants would prefer. A concern for others and for fairness allows us to internalize the effects of our actions on others, and so can contribute to good social outcomes. The scientific evidence is now overwhelming: climate change presents very serious global risks, and it demands an urgent global response. The British Chancellor of the Exchequer finance minister commissioned a group of economists, led by former World Bank chief economist Sir Nicholas now Lord Stern, to assess the evidence for climate change, and to try to understand its economic implications. The Stern Review predicts that the benefits of early action to slow climate change will outweigh the costs of neglecting the issue. Early action would mean a significant cut in greenhouse gas emissions, by reducing our consumption of energy-intensive goods, a switch to different energy technologies, reducing the impacts of agriculture and land-use change, and an improvement in the efficiency of current technologies.

    National governments disagree on the policies that should be adopted. Many nations in the developed world are pressing for strict global controls on carbon emissions, while others, whose economic catch-up has until recently been dependent on coal-burning technologies, have resisted these measures. The problem of climate change is far from unique. It is an example of what is called a social dilemma. Social dilemmas—like climate change—occur when people do not take adequate account of the effects of their decisions on others, whether these are positive or negative. Social dilemmas occur frequently in our lives. Traffic jams happen when our choice of a way to get around—for example driving alone to work rather than car-pooling—does not take account of the contribution to congestion that we make. Similarly, overusing antibiotics for minor illnesses may help the sick person who takes them recover more quickly, but creates antibiotic-resistant bacteria that have a much more harmful effect on many others.

    Fishermen as a group would be better off not catching as much tuna, and consumers as a whole would be better off not eating too much of it. Humanity would be better off by emitting less pollutants, but if you, as an individual, decide to cut your consumption, your carbon footprint or the number of tuna you catch will hardly affect the global levels. When one person cleans, everyone benefits, but it is hard work.

    Whoever cleans up bears this cost. The others are sometimes called free riders. If as a student you have ever done a group assignment, you understand that the cost of effort to study the problem, gather evidence, or write up the results is individual, yet the benefits a better grade, higher class standing, or simply the admiration of classmates go to the whole group. More than 2, years ago, the Greek storyteller Aesop wrote about a social dilemma in his fable Belling the Cat. Once the bell is on, the cat cannot catch and eat the other mice. But the outcome may not be so good for the mouse that takes the job. These actions are termed altruistic. Altruistic self-sacrifice is not the most important way that societies resolve social dilemmas and reduce free riding. Sometimes the problems can be resolved by government policies. For example, governments have successfully imposed quotas to prevent the over-exploitation of stocks of cod in the North Atlantic. In the UK, the amount of waste that is dumped in landfills, rather than being recycled, has been dramatically reduced by a landfill tax.

    Local communities also create institutions to regulate behaviour. Irrigation communities need people to work to maintain the canals that benefit the whole community. Individuals also need to use scarce water sparingly so that other crops will flourish, although this will lead to smaller crops for themselves. In Valencia, Spain, communities of farmers have used a set of customary rules for centuries to regulate communal tasks and to avoid using too much water. Since the middle ages they have had an arbitration court called the Tribunal de las Aguas Water Court that resolves conflicts between farmers about the application of the rules.

  • Looking For Other Ways To Read This?

    The ruling of the Tribunal is not legally enforceable. Its power comes only from the respect of the community, yet its decisions are almost universally followed. See also: game. Even present-day global environmental problems have sometimes been tackled effectively. The Montreal Protocol has been remarkably successful. It was created to phase out and eventually ban the chlorofluorocarbons CFCs that threatened to destroy the ozone layer that protects us against harmful ultraviolet radiation. In this unit, we will use the tools of game theory to model social interactions, in which the decisions of individuals affect other people as well as themselves. We will look at situations that result in social dilemmas and how people can sometimes solve them—but sometimes not or not yet , as in the case of climate change.

  • For Students

    But not all social interactions lead to social dilemmas, even if individuals act in pursuit of their own interests. Exercise 4. For each, specify how it satisfies the definition of a social dilemma. If you live in Japan, the UK, or Indonesia, you drive on the left. If you grew up in Sweden, you drove on the left until 5 p. The government sets a rule, and we follow it. But suppose we just left the choice to drivers to pursue their self-interest and to select one side of the road or the other. If everyone else was already driving on the right, self-interest avoiding a collision would be sufficient to motivate a driver to drive on the right as well. Concern for other drivers, or a desire to obey the law, would not be necessary. To analyse this, we will introduce game theory, a way of modelling how people interact. In Unit 3 we saw how a student deciding how much to study and a farmer choosing how hard to work both faced a set of feasible options, determined by a production function.

    This person then makes decisions to obtain the best possible outcome. But in the models we have studied so far, the outcome did not depend on what anyone else did. Neither the student nor the farmer was engaged in a social interaction. Social and strategic interactions strategic interaction A social interaction in which the participants are aware of the ways that their actions affect others and the ways that the actions of others affect them. See also: game theory. We use four terms: When people are engaged in a social interaction and are aware of the ways that their actions affect others, and vice versa, we call this a strategic interaction. A strategy is defined as an action or a course of action that a person may take when that person is aware of the mutual dependence of the results for herself and for others. Models of strategic interactions are described as games. Game theory is a set of models of strategic interactions. It is widely used in economics and elsewhere in the social sciences.

  • UNIT 8: EVOLUTION

    To see how game theory can clarify strategic interactions, imagine two farmers, who we will call Anil and Bala. They face a problem: should they grow rice or cassava? We assume that they have the ability to grow both types of crop, but can only grow one type at a time. Also known as: specialization. The two farmers have to determine the division of labour, that is, who will specialize in which crop. They decide this independently, which means they do not meet together to discuss a course of action. Assuming independence may seem odd in this model of just two farmers, but later we apply the same logic to situations like climate change, in which hundreds or even millions of people interact, most of them total strangers to one another. So assuming that Anil and Bala do not come to some common agreement before taking action is useful for us. They both sell whatever crop they produce in a nearby village market.

    On market day, if they bring less rice to the market, the price will be higher. The same goes for cassava. Figure 4. When an interaction is represented in a table like Figure 4. For example, the upper-left cell should be interpreted as: Suppose for whatever reason Anil planted rice and Bala planted rice too. What would we see? There are four possible hypothetical situations. To simplify the model, we assume that: There are no other people involved or affected in any way. The selection of which crop to grow is the only decision that Anil and Bala need to make.

  • Unit 1-2: Cladistics

    They decide simultaneously. Because the market price falls when it is flooded with one crop, they can do better if they specialize compared to when they both produce the same good. When they produce different goods they would both do better if each person specialized in the crop that was most suitable for their land. Question 4. A player decides his or her action, taking into account what other players may do after knowing his or her move. Players coordinate to find the actions that lead to the optimal outcome for society. A player chooses an action taking into account the possible actions that other players can take. A simultaneous game as opposed to a sequential game means that players all make a decision on their action simultaneously.

    In a one-shot game as opposed to a repeated game , each person only takes action once, without knowing what the other player s have chosen. The players take actions non-cooperatively, driven by self-interest. An essential element of strategic games is that each player takes into account the possible actions of other players, when the actual choices made are unknown.

    Game theory describes social interactions, but it may also provide predictions about what will happen. To predict the outcome of a game, we need another concept: best response. This is the strategy that will give a player the highest payoff, given the strategies the other players select. In Figure 4. A matrix is just any rectangular in this case square array of numbers.

    Science has good answers to these questions, answers that draw on the evidence supporting evolution and on the nature of science. This chapter presents short answers to some of the most commonly asked questions. Definitions What is evolution? Evolution in the broadest sense explains that what we see today is different from what existed in the past. Galaxies, stars, the solar system, and earth have changed through time, and so has life on earth.

  • Selection Test

    Biological evolution concerns changes in living things during the history of life on earth. It explains that living things share common ancestors. Over time, evolutionary change gives rise to new species. Darwin called this process "descent with modification," and it remains a good definition of biological evolution today. What is "creation science"? The ideas of "creation science" derive from the conviction that God created the universe—including humans and other living things—all at once in the relatively recent past. However, scientists from many fields have examined these ideas and have found them to be scientifically insupportable. For example, evidence for a very young earth is incompatible with many different methods of establishing the age of rocks. Furthermore, because the basic proposals of creation science are not subject to test and verification, these ideas do not meet the criteria for science.

  • Evolution 6 Unit 4 Worksheet

    Indeed, U. The Supporting Evidence How can evolution be scientific when no one was there to see it happen? This question reflects a narrow view of how science works. Things in science can be studied even if they cannot be directly observed or experimented on. Archaeologists study past cultures by examining the artifacts those cultures left behind. Geologists can describe past changes in sea level by studying the marks ocean waves left on rocks. Paleontologists study the fossilized remains of organisms that lived long ago.

    Something that happened in the past is thus not "off limits" for scientific study. Hypotheses can be made about such phenomena, and these hypotheses can be tested and can lead to solid conclusions. Furthermore, many key aspects of evolution occur in relatively short periods that can be observed directly—such as the evolution in bacteria of resistance to antibiotics. Isn't evolution just an inference? No one saw the evolution of one-toed horses from three-toed horses, but that does not mean that we cannot be confident that horses evolved. Science is practiced in many ways besides direct observation and experimentation. Teaching About Evolution and the Nature of Science. For instance, particle physicists cannot directly observe subatomic particles because the particles are too small. They must make inferences about the weight, speed, and other properties of the particles based on other observations.

  • Biology: A Global Approach, 12th Global Edition

    A logical hypothesis might be something like this: If the weight of this particle is Y, when I bombard it, X will happen. If X does not happen, then the hypothesis is disproved. Thus, we can learn about the natural world even if we cannot directly observe a phenomenon—and that is true about the past, too. In historical sciences like astronomy, geology, evolutionary biology, and archaeology, logical inferences are made and then tested against data. Sometimes the test cannot be made until new data are available, but a great deal has been done to help us understand the past. For example, scorpionflies Mecoptera and true flies Diptera have enough similarities that entomologists consider them to be closely related. Scorpionflies have four wings of about the same size, and true flies have a large front pair of wings but the back pair is replaced by small club-shaped structures.

    If Diptera evolved from Mecoptera, as comparative anatomy suggests, scientists predicted that a fossil fly with four wings might be found—and in this is exactly what was discovered. Furthermore, geneticists have found that the number of wings in flies can be changed through mutations in a single gene. Evolution is a well-supported theory drawn from a variety of sources of data, including observations about the fossil record, genetic information, the distribution of plants and animals, and the similarities across species of anatomy and development. Scientists have inferred that descent with modification offers the best scientific explanation for these observations.

  • Psychology 290

    Is evolution a fact or a theory? The theory of evolution explains how life on earth has changed. In scientific terms, "theory" does not mean "guess" or "hunch'' as it does in everyday usage. Scientific theories are explanations of natural phenomena built up logically from testable observations and hypotheses. Biological evolution is the best scientific explanation we have for the enormous range of observations about the living world. Scientists most often use the word "fact" to describe an observation. But scientists can also use fact to mean something that has been tested or observed so many times that there is no longer a compelling reason to keep testing or looking for examples.

  • Edmentum Answer Keys English 11

    The occurrence of evolution in this sense is a fact. Scientists no longer question whether descent with modification occurred because the evidence supporting the idea is so strong. Why isn't evolution called a law? Laws are generalizations that describe phenomena, whereas theories explain phenomena. For example, the laws of thermodynamics describe what will happen under certain circumstances; thermodynamics theories explain why these events occur.

  • Evolution: Frequently Asked Questions

    Laws, like facts and theories, can change with better data. But theories do not develop into laws with the accumulation of evidence. Rather, theories are the goal of science. Don't many famous scientists reject evolution? The scientific consensus around evolution is overwhelming. Those opposed to the teaching of evolution sometimes use quotations from prominent scientists out of context to claim that scientists do not support evolution.

  • Ives, Keith / Honors Biology Docs

    However, examination of the quotations reveals that the scientists are actually disputing some aspect of how evolution occurs, not whether evolution occurred. For example, the biologist Stephen Jay Gould once wrote that "the extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology. He was discussing whether the rate of change of species is constant and gradual or whether it takes place in bursts after long periods when little change occurs—an idea known as punctuated equilibrium. As Gould writes in response, "This quotation, although accurate as a partial citation, is dishonest in leaving out the following explanatory material showing my true purpose—to discuss rates of evolutionary change, not to deny the fact of evolution itself. Punctuated equilibrium accepts the conventional idea that new species form over hundreds or thousands of generations and through an extensive series of intermediate stages. But geological time is so long that even a few thousand years may appear as a mere "moment" relative to the several million years of existence for most species.

  • Ives, Keith / Honors Biology Docs

    Thus, rates of evolution vary enormously and new species may appear to arise "suddenly" in geological time, even though the time involved would seem long, and the change very slow, when compared to a human lifetime. Isn't the fossil record full of gaps? Though significant gaps existed in the fossil record in the 19th century, many have been filled in. In addition, the consistent pattern of ancient to modern species found in the fossil record is strong evidence for evolution. The plants and animals living today are not like the plants and animals of the remote past. For example, dinosaurs were extinct long before humans walked the earth. We know this because no human remains have ever been found in rocks dated to the dinosaur era. Some changes in populations might occur too rapidly to leave many transitional fossils. Also, many organisms were very unlikely to leave fossils, either because of their habitats or because they had no body parts that could easily be fossilized.
