![]() This is a textbook example of assumption passing as fact. The caption under the figure says that the pelvic bones “show structural change over time.” A bone itself cannot show structural change-that change must be inferred from the assumed ancestors and assumed ancestral function. Even though it has a clear reproductive function, evolutionists call it a left-over from a time when whales walked on land. The backbones may be bonded together to create one bone nevertheless, in. ![]() It is comprised of three to five vertebral bones. The coccyx, also known as the tailbone, is a tiny, triangular bone similar to a reduced tail situated at the lowermost part of the spine. Such features include not only anatomical structures but also physiological processes, biochemical reactions, and even behaviors. The figure on the left shows the supposed vestigial pelvis of a whale. EVOLUTION 2 Explain the function of the tailbone in humans (vestigial structures). Vestigial features of humans and other organisms are well known and have long been used as key evidence for evolution. But using observational science, it is impossible to identify exact ancestors or even the exact function of structures because observational science deals only with things that are observable in the present. This teaching is based on an assumption that is then passed off as science, an assumption that the ancestry and function of the structure is known. ![]() ![]() (Click to enlarge)Īlmost every secular biology textbook today includes a section on vestigial structures-structures that are supposed remnants from ancestors that have lost their original function or capacity.
