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.…
Evolution: descent with modification; the idea that living species are descendants of ancestral species that were different from the present-day ones.…
Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Given the right circumstances, and enough time, evolution leads to the emergence of new species.…
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- a gradual process in which something changes into a different and usually more complex or better form. The theory of evolution is a theory that many can argue to be true. Others will argue that it is not true. I believe that the theory of evolution is true.…

Over time, many theories have been developed concerning the way evolution was originated. One of these main theories was that Multicellular organisms originated slowly over the last billion years from unicellular organisms. Another main theory is that Multicellular organisms originated abruptly during the Cambrian (around 500 million years ago) explosion from unicellular organisms. While these two theories are very different from one another, many people support each of these ideas. However, I am very certain that the theory stating that they evolved slowly over the last billion years is correct, while the other theory is false.…
Evolution is the procedure which modern organisms have descended from the earliest ancestors. Evolution is accountable for both the similarities and the diversity across all species. Essential to the process is genetic variation on which selective forces can act in order for evolution to occur. Evolution can also be described as descent with modification. Evolution occurs when there is a modification in gene regularity in a population over time. These genetic differences can be inherited and may be passed on to the subsequent generations. The main idea of evolution is all life on earth shares a common ancestor.…
Evolution is a “process over time which enables us to adapt to our changing environments”. Charles Darwin was one of the founders of this theory whereby he identified that rather that a species being fixed at creation they gradually evolve from that of their common ancestors (Darwin cited in Clegg 2007) with characteristics and behaviours, that best suit the ever changing environment we live in, being passed down the generations in order to support survival.…
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: “descent with modification”; living species descend from ancestral species that differed from those that currently exist; change in genetic composition…
First off, the theory of evolution changes by natural selection as discussed by Darwin in "On the Origin of Species". The theory of evolution in relation to Darwin's idea states that organisms tend to adapt to its environment in order to survive and live on. There are two main points to the…
