- Hello! I have a discussion tommorow with my classmates, and the prompt says like this: Discuss whether changes to an organism's physical environment are likely to result in evolutionary change. Use examples to support your reasoning. Second, using at least two examples, explain how the process of evolution is revealed by the imperfections of living organisms.arrow_forwardScientists often talk about the evidence for evolution. Using the five types of evidence listed here, explain how each suggests the occurrence of evolution: 1) structural homologies, 2) molecular homologies, 3) developmental homologies, 4) fossils (general) and 5) transition fossils.arrow_forwardA new organism has been discovered! Our fictional creature, “the Snipe”, has structural similarities to a deer, pig, and beaver. It has a pig’s head with antlers, and big buck-teeth, a deer’s body, and a wide, flat tail. Please describe how you could determine its place on the evolutionary tree below. Please draw an evolutionary tree to demonstratearrow_forward
- Using the information in Figure , draw a simple cladogram that represents areasonable hypothesis of human evolution at the genus level. (Hint: Your diagram will have three branches.)arrow_forwardWhich of the following does NOT provide evidence for the theory of evolution? the existence of homologous and vestigial structures structural and chemical homologies recorded observations of an individual organism in a population fossils presence of DNA in all organismsarrow_forwardJellyfish Lake, located on the Pacific island of Palau, is home tomillions of jellyfish. Many years ago, sea levels dropped and thejellyfish were trapped in the basin. The lake contains no predators,and the jellyfish’s sting has weakened. Jellyfish Lake is now a populartourist attraction where snorkelers can swim among the jellyfish.Explain how Jellyfish Lake is evidence for evolutionarrow_forward
- Consider Theodosius Dobzhansky’s remark, “Nothing in biologymakes sense except in the light of evolution.” Why is evolution soimportant to the field of biology? Give some specific examples of howthe theory of evolution helps us to make sense of biology.arrow_forward'The origin of life is a co‐evolutionary process.' Briefly explain.arrow_forwardTarsiers are one of the small species of primates generally found in tropical islands like Bohol, Philippines. Gibbons are small apes usually found in the forests of Southeast Asian regions. Chimpanzees are considered to be the highest form of "thinking organisms" on Earth. The theory of evolution asserts that these species evolved from a related ancestor. By observing the given figure. How will you support or reject the said claim?arrow_forward
- Theodosius 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?arrow_forwardPut this in a 400-word paragraph The Development of Evolutionary Theory, Lecture 2 This 17th-century map shows the Earth at the center of the solar system. • Ideas generated out of the Scientific Revolution challenged such long-standing beliefs. • Aristotle argued that the sun and the planets revolved around the earth. George-Louis Leclerc, Comte de Buffon (1707-1788), recognized the dynamic relationship between the external environment and living forms. • Although he never discussed the diversification of life over time, he recognized that different regions have different plants and animals and that alterations of the external environment (such as climate) were agents of change. • Some scientists today (Ernst Mayr) credit Leclerc as the “father of evolutionism Jean-Baptiste Lamarck developed a theory to explain the evolutionary process, known as the inheritance of acquired characteristics. • An example is the giraffe: having stripped the leaves from the lower branches of a tree,…arrow_forwardWhich of the following statements about evolution is false?a. Gene mutations alone amount to evolution. b. Genetic drift and gene flow are modern theories of evolution.c. Natural selection contributes to evolution.d. Chimpanzees evolved from a hominoid ancestor.arrow_forward
