DNA amp The Genetic Code Fossil Record Strata amp Superposition Relative Age vs Absolute Age Fossil Record Per the theory You would expect older rock to contain mostly organisms that are less complex and less like current living organisms. Objectives. Explain prenatal development from fertilization to birth. Understand different biological process’ in all phases of prenatal development. Define key vocabulary. Chart different phases in . Book Study Guide (Assigned Monday 4/6). Answers. Chapter 15. 1. Natural selection is a mechanism for…. EVOLUTION. 2. __________ was used to produce purebred Chihuahuas and cocker spaniels.. ARTIFICIAL . . give . examples of types of evidence that Darwin gathered to develop the theory of evolution;. Structural similarities among organisms.. Geographic distribution of organisms.. The embryological similarities among organisms.. The fossil record. Anatomical, embryological, cellular and molecular similarities. Artificial selection . can be used as evidence for the evolutionary development of a given species. HS‑LS4‑1. Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.. nd. , 2014 . Give one example of an adaptation and explain . why. it is an adaptation. . Define evolution by natural selection.. 3. Give an example of geographic isolation. . 4. How are convergent and divergent evolution different? . Organism DNA. 1a. Some of the strongest evidence for evolutionary relationships comes from studying the DNA of different organisms.. 1b. The fact that all organisms use the same DNA molecule to code for genetic information suggests that these organisms share a distant ancestor.. Derived traits. are newly evolved features, such as feathers, that do not appear in the fossils of common ancestors. .. Ancestral traits. are more primitive features, such as teeth and tails, that do appear in ancestral forms.. Archeopteryx. : A transition fossil between reptiles and birds..

Explain prenatal development from fertilization to birth. Understand different biological process’ in all phases of prenatal development. Define key vocabulary. Chart different phases in . somitogenesis. Formation of the Digestive Cavity. At the Blastula stage, the embryo forms a fluid filled ball of cells. During Gastrulation, the blastula caves in on one end to form a Gastrula. The cavity formed by gastrulation will form a digestive cavity or digestive tract.. Fossil evidence for evolution. Most evidence of evolution was originally found in fossils. Fossils can preserve the structure of organisms in sedimentary rock if conditions are just right. . One area of evidence of evolution is embryology, the study of embryos. When we compare embryos we can see shared characteristics of organisms throughout their developmental process. . Structures. - features similar in structure, but appear in different organisms with different functions.. Analogous structures-. structures similar in function, but are not similar in origin..
