Evolution: descent with modification; the idea that living species are descendants of ancestral species that were different from the present-day ones.…
• Biological evolution is defined as any genetic change in a population that is inherited over several generations. These changes may be small or large, noticeable or not so noticeable.…
Evolution has remodeled how everything in biology is observed and analyzed. Darwin’s concept of evolution through natural selection has important meaning to it. This idea could be used to picture how a few small changes can build up over a period of time and make it possible to explain how something in a plant or animal developed. (Charles Darwin – English Naturalist and Philosopher –…
Evolution is the building blocks to biological science. If we did not care about evolution, we would not understand the concept of biology, or any type of science for that matter.…
Evolution is the change in genetic composition of organisms between generations. Evolution is the process that results in organisms becoming more varied and better adapted in comparison to their ancestors. The driving force of evolution is natural selection. Natural selection is the process where individuals containing specific traits become more likely to survive compared to individuals without those traits. Because certain individuals have a greater chance to survive, they become more likely to reproduce yielding offspring that contain the same favored characteristics. As this occurs, the number of individuals with preferred traits become more abundant while the population of individuals without these traits begins to decrease, possibly even reaching the point of complete elimination.…

Evolution is basically the change in the heritable characteristic or traits in living organisms which are passed from one generation to another and gives rise to diversity at every stage of the organism’s biological organisation. The process of evolution was not well understood until 19th century when Charles Darwin proposed the scientific theory of natural selection as a driving tool in evolution. The process involved both the macroevolution in which organisms went through major evolutionary changes over a long period of time and acquired different traits from different parents or ancestries and the microevolution in which a group of organisms went through minimal changes with time but the traits they acquired were typically from the same ancestor.…
Darwin’s theory of evolution is based on the theory of natural selection. Natural selection is the the process whereby organisms better adapted to their environment tend to survive and produce more offspring. This theory is now widely believed by many people throughout the world. Charles Darwin’s theory includes the idea that fossils of extinct animals turn up where similar animals live today. Darwin came up with this theory when he discovered fossils of animals that were very similar to the animals that were living today. Darwin also observed that the Galapagos tortoise’s had different shapes of their shells depending on which island they came from. Darwin believed that these tortoises were adapting to their environment by changing their shell…
Charles Darwin provided a mechanism for the theory of Biological Evolution, which is what separates him from previous researchers. Before Darwin’s theory of biological evolution by natural selection, the ancient Greeks were the first to attempt to understand our place in the natural world. Following the Greeks, was Aristotle, he believed that each living form had attributes that could not be altered, therefore, fitting in an ordered rank ladder, and that human beings were at the top of the ladder. Before the 19th century most naturalist believed that there was a single creation event—influenced by the church’s beliefs (Stanford 17). Even then, naturalists continued to develop classifications for animals and plants. John Ray was the first to…
Evolution, as suggested by Charles Darwin, is described as the concept or scientific theory. He believed species…
Evolution: “descent with modification”; living species descend from ancestral species that differed from those that currently exist; change in genetic composition…
Evolution is split into to two central concepts. The first is universal common descent, it is the idea that every living creature can be traced back to an unbroken lineage to the same life forms that back then were primitive. The second is natural selection which that the entire complexity and intelligence of life has evolved by many small random mutations. These mutations help organisms survive in many different environments.…

Evolution is simply the process of organisms developing and diversifying from a previous earlier form during the history of the earth. The four forces evolution, what is believed to push evolution to go forward, are mutation, natural selection, genetic drift, and gene flow. Let's start with mutation.…
