- how do scientists support the theory of evolution? use the terms evolution, natural selection, vestigial structures, homologous structures, DNA, adaptations and fossilTheodosius Dobzhansky wrote “Nothing in biology makes sense except in the light of evolution.” What did he mean by this? How does evolution unify the biological sciences? What other principles might do so?What is the role of the tree of life in studying evolution?
- What did Darwin’s travels reveal to him about the number and variety of living species? How did tortoises and birds differ among the islands of the Galapagos? What is evolution? Why is referred to as a theory? Darwin found fossils of many organisms that were different from any living species. How would this finding has affected his understanding of life diversity?what are the differences between creationism and the theory of human evolutionWhy are vestigial structures among organisms evidence for evolution? Give an example of another vestigial structure.
- What is one of the common misconceptions about human evolution?Why did Darwin reffered to "decent with modification" rather than the term "evolution".What term did Lamarck use to explain how new species emerged? What term did Darwin use to explain how new species emerged Do you think there is any similarity in the theories proposed by the two scientists? Explain.
- How has ecology influenced evolution?What is scientific classification? Why does biologist classify organism? Enumerate the scientist and cite their respective contributions in the development of evolutionary thought.How is the increased similarity in the DNA sequences of genes between more closely related organisms—and the decreased similarity between less closely related organisms— evidence for evolution?
