- Studying evolution is an excellent way for students to learn about the process of scientific inquiry. Evolution offers countless and diverse examples of the ways scientists gather and analyze information, test competing hypotheses, and ultimately come to a consensus about explanations for natural phenomena.

An Introduction to Evolution The fossil record provides the foundation for understanding the evolution of life on Earth. The fossil record provides the raw data—the evidence—that enables us to describe the living organisms of the past.

What do scientists mean when they call evolution a theory? Like gravity and plate tectonics, evolution is a scientific theory. In science, a theory is the most logical explanation for how a natural phenomenon works. It is well tested and supported by abundant evidence. It means quite the opposite from our informal use of the word theory, which implies an untested opinion or guess. As a scientific theory, evolution enables scientists to make predictions and drives investigations that lead to new kinds of observable evidence.

The Importance of Teaching Human Evolution Students should understand our biological place in the world. Teaching human evolution is too important to avoid for fear of the controversy surrounding it. I have seen the moment in which a student begins to comprehend the bigger picture of where we come from, and it is amazing to behold.

- Anthropologists and archeologists often do fieldwork. Anthropologists and archeologists study the origin, development, and behavior of humans. They examine the cultures, languages, archeological remains, and physical characteristics of people in various parts of the world.iological anthropologists, also known as physical anthropologists, research the evolution of the human species. They look for early evidence of human life, analyze genetics, study primates, and examine the biological variations in humans. They analyze how culture and biology influence each other.

- To study frequency changes, we analyze populations rather than individuals. Furthermore, because changes in gene frequencies are at the heart of evolution and speciation, population and evolutionary genetics are often studied together. For a population of individuals to succeed over evolutionary time, it must contain genetic variability.

Human evolutionary genetics Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to it, and its current effects.

Evolutionary Psychology Many evolutionary biologists and other scientists are still reluctant to recognize evolutionary psychology as a valid science. Much like Charles Darwin's ideas about natural selection, evolutionary psychology focuses on how favorable adaptations of human nature are selected for over less favorable adaptations. In the scope of psychology, these adaptations could be in the form of emotions or problem-solving skills.

- DNA shapes how an organism grows up and the physiology of its blood, bone, and brains. DNA is thus especially important in the study of evolution. The amount of difference in DNA is a test of the difference between one species and another – and thus how closely or distantly related they are.

Evolution's Importance to Society But largely I would think the genetics in the first and molecular and evolutionary biology especially in the second half of the 20th century clearly demonstrate that biology is very much relevant to everyday life. We now understand the basics of how human beings are put together.

- But scientists spend their careers studying meteorites because they contain a record of our solar system's history going back some 4.6 billion years. By studying meteorites, we can learn details about how our solar system evolved into the Sun and planets of today—and how meteorite impacts could affect our future.

Evolution Evolution influences every aspect of the form and behaviour of organisms. Most prominent are the specific behavioural and physical adaptations that are the outcome of natural selection. These adaptations increase fitness by aiding activities such as finding food, avoiding predators or attracting mates.

Why is evolution considered a theory? Because it is a theory explaining the mechanisms of evolutionary change it is useful, the theory of descent with modification by natural selection helps biologists understand how species impact each other.

- (Answer #7). Archaeology plays a huge role in the study of history. Archaeology helps us learn more about how past societies lived and how the human race developed. This is why we learn about history. We learn about history to understand about the past to better understand why we are where we are today.Answer #1). Archaeology can play a very important role in the study of history. It is, of course, more important for the study of prehistoric times, but it can be important even when we study more recent events.

- Chromosomes and Evolution Evidence. Chromosomes, or the higher order structures that contain genes, are also analyzed to support the theory of evolution. Scientists compare chromosomes among species or other large groups of living organisms and “tally up” the differences.

Evolution Evolution is a scientific theory used by biologists. It explains how living things change over a long time, and how they have come to be the way they are. Earth is very old. By studying the layers of rock that make up Earth's crust, we can find out about its past. This kind of research is called historical geology.

Evolution??? That's why the term theory of gravity is used. In science, a theory is an explaination. Evolution is a fact, because we see organisms evolving in real time, and we have the trail of the fossil record to support long term changes. Otherwise, read haysoos2's answer...he covered the answer very well.

Evolutionary Psychology Without applying evolutionary theory there is no scientific way to say whether a behavior is adaptive (serves a purpose) or not (see Intentional Design.) Ordinary psychology is to evolutionary psychology as geography is to geology. Geography describes the shape of the land, while geology is concerned with the processes that shaped the land—how it got the way that it is. Evolutionary psychology attempts to explain human motivations and behavior as being the consequence of evolution. Behaviors and capacities are assumed to be adaptive: to enhance survival and reproductive success. Evolutionary psychology is a large and rapidly growing field, and we won't attempt to summarize it here. See Evolutionary psychology and books such as The Happiness Hypothesis and The Tangled Wing that apply the perspective of evolutionary psychology to understanding the human condition.

- 1 Evolution may not say that there's no God, but it certainly seems to say that God plays no part in the way the world works.  Many people say that, after studying both creation and evolution as explanations for life's history, they feel that both are forms of faith. This is because they deal with events that occurred prior to human history. These people say that to accept either explanation requires trust and and element of belief.

Evolution The precision with which these events can be reconstructed is one reason the evidence from molecular biology is so compelling. Another reason is that molecular evolution has shown all living organisms, from bacteria to humans, to be related by descent from common ancestors.

- Paleontology is the study and interpretation of fossils. Fossils can be useful in several ways. Paleontologists use fossils to help determine ancient environments and the ages of rock beds. A fossil may be direct remains of a part of an organism, such as teeth, bones, or shells. In addition evidence of past life such as a footprint or a gizzard stone are known as trace fossils.

What is a Paleontologist? A paleontologist studies the history and process of evolution by examining fossils, the preserved traces of long dead animals and plants. Using data from fossilized bones, ancient pollen, and other clues, paleontologists dig up the details on past climates and past extinctions.

Why do populations evolve? Evolution is a phenomenon best expressed in terms of either changes between generations or changes in allele frequencies from one generation to the next. It is individual vari…ants that are subject to natural selection, but evolution is most easily measured in terms of allele frequencies in the population gene pool.

Evolutionary Genetics Evolutionary genetics is the broad field of studies that resulted from the integration of genetics and Darwinian evolution, called the ‘modern synthesis’ (Huxley 1942), achieved through the theoretical works of R. A. Fisher, S. Wright, and J. B. S. Haldane and the conceptual works and influential writings of J. Huxley, T. Dobzhansky, and H.J. Muller ...
