In all parts of the world, past and present, humanity seeks the answers to how the Earth and its complex life forms came to be. Over the years, many theories have surfaced, but the most popular is the theory of evolution. Evolution is now taught in science classrooms around the world, with concepts based on Charles Darwin's theory of evolution and natural selection. The scientific community has accepted that evolution explains how the Earth took shape. however, since no one was present when the earth was created, no one knows for sure, but there is a theory that explains how, why, and when, and that is creation. That there is a supreme force: God. Neil A. Campbell, Ph.D. in plant biology from the University of California, and Jane B. Reece, Ph.D. in bacteriology, also from the University of California. They and their colleagues discuss the theory of evolution at length in their Biology textbook. In the textbook, they discuss Charles Darwin, who was an English naturalist who spent his life studying the origins of the Earth and all of its complex life. Darwin is known as the father of evolution. “He traveled to the Galapagos Island in the Pacific Ocean, aboard the HMS Beagle. It was here that he studied the adaptation of different plants and animals” (quoted in Campbell et al. 441). At the end of his journey, he returned home and wrote his book On the Origin of Species. By means of natural selection or the preservation of the favored in the struggle for life (Campbell et al. 441). According to Campbell, natural selection is the driving force behind the theory of evolution. Over time, natural selection can also force more and more species to adapt to the changing environment. Evolutionists believe that all species...... middle of article...... results. Evolution violates this fundamental premise because it cannot be directly observed or repeated. Evolutionists argue that genetic variation caused by natural selection is observable evidence. for evolution. However, this is a post-hoc error. Such variation only proves that there is variation between species. This does not show that new genes or information have been formed. No species has been observed transforming into another, currently or in the fossil record. Yes, organisms adapt through microevolution, but that doesn't mean they will eventually become a separate species. Although scientists claim to find evidence for evolution in both homology and the fossil record, contrary evidence has surfaced, leading scientists to search for irreducible complexity and its importance in the evolution debate . For this reason, evolution remains only a theory.
