Evolving Planet

What is evolution? Evolution in modern terms is fairly easy to understand. Evolution is the theory that life on earth began with a single celled organism that lived more that 3.5 billion years ago that slowly evolved into

According to Ms. Witsaman, evolution is not the theory of how life began, which is a common misconception nowadays, but the theory of how life has changed over time. Theories are predictions which are backed up by several evidences and supported by scientists. The evidences that scientists use now to prove include fossils, homologous structures, analogous structures, vestigial structures, embryology, biogeography, and biochemicals. Fossils are the remains of living things that once roamed the Earth. Homologous structure are structures shared by different organisms that have similar structure but different functions. Analogous structures are the opposite, they have similar functions but completely different structure.Vestigial structures are

Evolution: the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

What is evolution? Evolution is a change in the traits of living organisms over generations. Since the development of modern genetics in the 1940s, evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation

According to Dr. James Krupa of The University of Kentucky “evolution is the foundation upon which all biology rests.” In biology, evolution is the genetic change in characteristics over generations and is dependent on the process of natural selection. ‘The theory of evolution is based on the idea that all species are related and gradually change over time’ (Genome Campus, 2017). Genetic variation is vital to evolution as it affects the physical characteristics or phenotypes of morphology. Natural Selection is affected by environmental factors that act upon a population and result in the mutation of organism through offspring. These mutations enable individuals to adapt to their environments in order to survive, find food, avoid predators and

Introduction: Evolution is the change over time for an organism or thing. As in how organism were quadrupedal to bipedal and how organisms bodies adapted to a form to better support its body in its environment. Evolution is based and showed as the changes to an organism over time, and it explains the common ancestry to two common species. The biggest evidence scientist use regarding evolution is fossils.

Evolution is the key thread running throughout this text, signifying its importance to the author and readers. It is emphasized greatly because that is how we understand ourselves, our past, present and even the future. Through evolution we have discovered when the first organisms came around and how modifications led to the first fish to migrate to land about 375 million years

Evolution is a mysterious topic, as there is just so much evidence that has been found by many people throughout history. The first person to spread the idea of evolution was Charles Darwin. He helped to spread the idea of evolution to others such as Gregor Mendel, and helped many others to accept the findings of Boucher de Perthes. Evolution is defined by the changes of organisms throughout time to better the survival rate of said group of organisms.(definitions, 2009) The generations of organisms therefore evolve through time as the changes occur. There are many pieces of evidence such as, analogous and homologous structures in organisms, cladograms, the order of appearance of structures during embryological development, and fossil records. Evidence of evolution at it’s finest.

Every living thing on Earth has evolved into its current form over the course of millions of years. The theory of evolution explains how these organisms changed over time through natural selection. Evolution is still controversial within our society because it conflicts with religious beliefs on how life on earth formed.

The definition of evolution is that species over time will change. They will start to adapt over time and become a new species. You see this happening throughout the world and over the course of our planets history. In this lab we will be testing different hypothesis and observing them to make conclusions if they can be justified or not. There are three different parts first is the Artificial and Natural selection, the second is the fossil record, third is comparative anatomy, biochemistry, embryology and the last is Biogeography.

The word is now accepted to mean the change of nonliving chemicals into simple life-forms into more complex life-forms and finally into humans.” (Answers in Genesis 1). Despite the many claims that “evolution” simply means a change, scientifically speaking it means much more. Evolutionary ideals describe changes that allow scientists to date life on the earth to be 4.5 billion years, to trace the entire living population of every animal, insect, plant, virus, and bacteria back to one simple cell, and to conclude that the first cell supposedly came into being sporadically from a pool of organic molecules (Archean 1). Science cannot factually support evolutionary concepts because evolution cannot be tested; observation holds a critical role for experiments to take place, yet spontaneous creation of a cell has not recurred since the alleged first living cell created itself. Evolution cannot be proven, and therefore, the public school system should not teach evolution as fact, especially with no exposure to alternative concepts.

Evolution is the development of something from a simple form to a more complex one. Evolution is classified as a scientific theory because there is still some evidence needed so that evolution can be proven true. The evidence scientists have regarding evolution to lead to the conclusion that evolution is a reliable-theory are, relative dating,embryology, and homologous structures. The purpose of this lab was to learn the way in which human ancestors evolved into today’s human species.

I remember when I was in grade school we went on a field trip to the San Diego Museum of Man. It was such an interesting field trip. I remember our tour guide telling us about evolution and how there was a theory that us humans were once primates. Then I remember meeting her. They brought us to a room where there was a partial skeleton in a glass container. There was Lucy. I was told she was the first of her species to be discovered. She must have made a very large print in the theory of evolution. Ever since my trip to the museum and meeting Lucy, I have been fascinated with the whole idea of evolution. According to a journal entry written by W.J. Bock, he says evolution is the general notion that living organisms descended down from a common ancestor (2007:89). Over the past few weeks I have done extensive research and explored the theory of evolution. My findings have suggested that because of scientific discoveries such as fossils, natural selection, and taxonomy, evolution has made a significantly strong case.

Evolution refers to "change over time". In terms of physical anthropology, evolution is changes over time in living organisms. This means that living things have passed their traits from one generation to the next. There are very little changes that occur with each generation, but over time these changes accumulate in each living organism. It is believed that all life on Earth has common ancestry that lived more than 3.5 billions of years ago (Park, 2008).

The theory of evolution is significant as repeated testing that explains “an observable, verifiable truth – that life on this plant has changed over time.” (Fuentes, 22) It is the well-supported history of where all life came from on this planet.
