The materials are arranged in different learning paths like "What does T. rex look like?" Charles Darwin's theory of natural selection states that over time, animals that are more adaptable to changing environments thrive, and those that do not become extinct. Science is concerned with this process of biological evolutionary change. What is Evolution? The term "evolution" can have many nonscientific meanings, such as "progress" or "descent with modification." It is scientifically based and is used to describe the process of changing characteristics in a species or species. In biological terms, this change is due to natural selection and genetic drift. Evolution is a key concept in the field of biology today. It is an established theory that has stood up to the test of time and thousands of scientific tests. Evolution does not deal with the existence of God or religious beliefs in the same way as other theories of science, such as the Copernican or germ theory of diseases. Early evolutionists, like Jean-Baptiste Lamarck and Erasmus Darwin (Charles's grandfather), believed that certain physical traits were predetermined to change in a step-wise way, over time. called this the "Ladder of Nature" or scala naturae. Charles Lyell used the term to describe this concept in his Principles of Geology, first published in 1833. In the early 1800s, Darwin formulated his theory of evolution and published it in his book On the Origin of Species. It states that all species of organisms share a common ancestry which can be traced by fossils and other evidence. This is the current view of evolution, which is supported by a variety of disciplines which include molecular biology. While scientists do not know the exact mechanism by which organisms evolved but they are certain that the evolution of life on earth is a result of natur
