Chapter 10. Biological Evolution. Evolution the word, has several meanings. Evolution – gradual change to improve or become more complex - change. Evolution – random changes made by chance to get what we see today – goo to you (theory of evolution). UNIFYING CONCEPTS IN ANIMAL STRUCTURE AND FUNCTION. STRUCTURE FITS FUNCTION IN THE ANIMAL BODY.

Evidence for evolution can come in the form of anatomy and physiology. For example vestigial, analogous, and homologous structures. . Vestigial Structure:. The concept of vestigiality applies to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species. An example is the human appendix..
