Concept 3: Evidence of Evolution 2023.List and describe the fields of study that provide evidence for the theory of evolution. - ANSWERPaleontology- - reveal different species (extinct) and ages of those fossils PREHISTORIC LIFE Biogeography-Island species most closely resemble inland species *adapted to the island, population shows variety on different islands DIVERGENT EVOLUTION PATTERNS Embryology- embryos of vertebrates are very similar in appearance COMMON ANCESTRY W VERTEBRATES Anatomy- similar characteristics resulting from COMMON ANCESTRY Homologous structures-same structure, different function, DIVERGENT EVOLUTION, greater # of shared structures, more close relation Vestigial organs-structures without any function to the organism, remnants of structures that had important functions. DIVERGENT EVOLUTION. tail bone Analogous structures-similar function, different structure. similar structures for similar environments. CONVERGENT EVOLUTION Biochemistry-DNA and Proteins- similarities in DNA and Amino acid sequences in different species to find common ancestry, 2 closely related will have similar DNA sequence. Pseudogenes- look like genes, but don't function. (vestigial structures of genes) Explain the difference between homologous, analogous, and vestigial structures. Be sure to indicate which pattern of evolution leads to these structures, as well as an example of each. - ANSWERALL COME FROM ANATOMY- Homologous structures-same structure, different function, DIVERGENT EVOLUTION, greater # of shared structures, more close relation ( arm of a human, the wing of a bird or a bat, ) Vestigial organs-structures without any function to the organism, remnants of structures that had important functions. DIVERGENT EVOLUTION. (tail bone) Analogous structures-similar function, different structure. similar structures for similar environments. CONVERGENT EVOLUTION (different wings in animals) List the 2 macromolecules that provide evidence for evolution in the field of biochemistry. - ANSWERDNA and proteins Describe relationships between organisms based on evidence gathered in various fields of study within biological evolution. - ANSWERMany organisms contain similar traits to another because of biological evolution. As time progresses, habitats change and an organism must adapt itself. Vocabulary - ANSWERBiogeography: the study of where living things are located. Anatomy: study of the structure of organisms. Homologous structures: similar characteristics from common ancestry
