It is known that it takes very long periods of time for new species to develop, and yet the fossil record for many organisms is characterized by long periods of Stasis (no change) followed by short bursts of intense Speciation (the disappearance of one species followed by the appearance of a new species). Thus in the fossil record, organisms seem to stay the same for long periods of time followed by a “sudden” change in the organisms (sudden with respect to evolution and geology). In other words, it appears that new species evolve suddenly as opposed to over long periods of time. The Theory of Punctuated Equilibrium helps to explain these seemingly contradictory occurrences in the fossil record. Discuss how Punctuated Equilibrium works (think about small offshoot populations that break off from the main population) and how it can explain the fossil record evidence. (Be sure to include information about why fossils of the offshoot population would be rare.)
Discuss the process of evolution through natural selection. What could happen to the ecosystem and animals in ten, one hundred, or one thousand years? Is it feasible for them to continue evolving or do they eventually become extinct? Explain your answer concisely.
In the early nineteenth century, the French scientist Georges Cuvier provided conclusive evidence of the
extinction of species on Earth. Although Cuvier correctly asserted that a series of catastrophes led to these
extinctions, he could not provide a testable explanation of the source of the new animals and plants that
appeared after the extinction of older forms. How would you argue that modern evolutionary theory provides
an explanation for the proliferation of new forms of life after mass extinctions?

- This phylogeny consists of two distinct genera of cat; one with one species (P. aliquam) and another of three species (the red box indicates their distance). The species have three main physical traits: coat colour, ear tufts and tail shape. At the ancestral nodes of the tree, it can be seen what the ancestor of these species looked like for these three traits. Each of these traits has undergone a different type of evolution. Choose one type of evolution and explain the mechanism that brought the given characteristics.arrow_forwardDefine the following terms: divergent evolution, convergent evolution, analogous structures, homologous structuresarrow_forwardA scientist used satellite images to track the natural habitats of two species of salamanders: E. eschscholtzii (shown in green) and E. klauberi (shown in brown). What type of evidence of evolution is this? *arrow_forward
- Fossils show that dinosaurs originated between 200 and 250 million years ago. Would you expect the geographic distribution of early dinosaur fossils to be on multiple continents or on a single continent? Explain. Hint: refer to continental drift in your explanation.arrow_forwardUse the evolutionary tree below to answer the following questions:arrow_forwardAll the following statements support the theory that similar organisms have a common ancestor except Select one: a. similar DNA patterns occur in closely related organisms b. organisms sharing a habitat tend to develop similar behaviours c. transitional fossils show links between groups of organisms d. groups of organisms display similar embryonic developmentarrow_forward
- Which of the following is false concerning the evidence for evolution? Vestigial structures are a reduced structure or organ that was once useful to an ancestral species. B The more closely related two species are, the fewer DNA base differences there is. In radiometric dating, fossils with more stable elements are younger than fossils with radioactive elements. D Species that share a common ancestry will have homologous structures.arrow_forwardTransitional species are species important in helping scientists determine the evolutionary path that species have taken over long periods of time. Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? Question options: Skeletal structures that indicate the development of legs. An intermediate structure between lungs and gills. Teeth that are intermediate to the lobe-finned fishes and amphibians. A neck that is more flexible than lobe-finned fishes.arrow_forwardWhich of the following statements about the fossil record is true? a. The fossil record is a complete accounting of life on earth b. The fossil record is unbiased in the fossils that are found c. The fossil record is evenly sampled across all of life's history on earth d. There are certain biases in the fossil recordarrow_forward
- Evolution is the theory that species change over time. According to this theory, new species form from existing species through variation and natural selection. The evolutionary process is very slow and the transformation of one species into another requires thousands of years. Several evidences are used to prove evolution and somehow reconstruct how this process occur: 1.Fossil Records. 2.Homologous Body Structures. 3.Vestigial structures. 4.Similarity of embryo. 5.Geographical evidencearrow_forwardAssume you are studying two different species of plants that have evolved purple flowers. You reconstruct the ancestor of these plants and discover the ancestor plant had pink flowers. You decide to investigate the development of the purple flowers and find that the plants both evolved purple flowers via the same purple pigment gene pathway. This discovery is best described as which of the following? a. Equal Fitness Landscapes b. Heterochrony c. Parallel Evolution d. Convergent Evolutionarrow_forwardWhat is the difference between micro- and macroevolution? a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants. b. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms. c. Microevolution describes the evolution of populations, while macroevolution describes the emergence of new species over long periods of time. d. Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.arrow_forward
