Example Of Convergent Evolution Quizlet

see definition of convergent evolution noun adaptive evolution Relevance ranks synonyms and suggests the best matches based on how closely a synonyms sense matches the sense you selected. evolution [evolushun the process of development in which an organ or organism becomes more and more complex by the differentiation of its parts; a continuous and progressive change according to certain laws and by means of resident forces. convergent evolution the development, in animals that are only distantly related, of similar structures or. convergent evolution The development through evolution of similar features by organisms with distinctly different ancestors. A common example of this is the evolution of wings in insects and birds. Convergent evolution the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait is rife in nature, as illustrated by the examples below. The ultimate cause of convergence is usually a similar evolutionary biome, as similar environments will select for similar traits in any species occupying the same ecological niche, even if those species are. Convergent evolution refers to the kind of evolution wherein organisms evolve structures or functions in spite of their evolutionary ancestors being very dissimilar or unrelated. Analogous structures pertain to those structures of unrelated (different) organisms having the. Convergent evolution is when different organisms evolve to display similar traits which serve similar functions. For example, the wings of a bat, bird, and bee are fundamen tally different in. Evolution, which can be defined as the natural change in the inherited characteristics of groups of organisms, is as well established as the Roman Empire or any other event that is accepted as fact. Unfortunately, the common phrase theory of evolution has misled many people into believing that evolution is only a theory. This example of convergent evolution is particularly of interest to biologists because to find common ancestors between our two species, one would have to go back over 500 million years, when only primitive versions of the Pax6 gene existed. In cultural evolution, convergent evolution is the development of similar cultural adaptations to similar environmental conditions by different peoples with different ancestral cultures. An example of convergent evolution is the similar nature of the flightwings of insects, birds, pterosaurs, and bats. Convergent evolution is the process by which unrelated or distantly related organisms evolve similar body forms, coloration, organs, and adaptations. Natural selection can result in evolutionary convergence under several different circumstances. Convergent vs Divergent Evolution When considering living organisms, evolution can be defined as the development of differentiated organisms from less differentiated pre. A classic example of convergent evolution is the Tasmanian Tiger (a marsupial native to Australia) and members of the dog family (which are all mammals). The two animals appear remarkably alike physically, but geographical separation and evidence from the fossil record militates against the idea that one evolved from the other or both evolved. Camera eyes: the repeated evolution of camera eyes (i. eyes that use a lens) is one of the most striking examples of convergent evolution. Camera eyes have independently evolved in cnidarians (certain jellyfish), cephalopods (such as squid and octopus) and vertebrates (birds, mammals). The marine environment is comprised of numerous divergent organisms living under similar selective pressures, often resulting in the evolution of convergent structures such as the fusiform body shape of pelagic squids, fishes, and some marine mammals. However, little is known about the frequency of, and circumstances leading to, convergent evolution in the open ocean. Herre is a lesson on divergent and convergent evolution. It has links to terrific video clips, an associate worksheet, and more. The analysis questions have been reviewed separately on Lesson Planet if you would like more information. Convergent evolution is the independent evolution of similar features in species of different lineages. The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Start studying Coevolution, Convergent Evolution, Adaptive Radiation, Punctuated Equilibrium Example of convergent evolution quizlet. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Example of convergent evolution quizlet The Convergent example asks for a vehicle, whereas the Divergent example doesnt rule out options like moving closer to work, telecommuting, walking, carpooling, taking public transportation, etc. Both examples will produce valuable results. Convergent Evolution is a common theme in the evolution of animals. It always occurs when two unrelated species independently evolve similar traits to cope with specific evolutionary challenges, like living in ice cold water or eating ants. Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. A species can evolve by only one of these, or by both. Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly. evolution of the horse Evolution of the horse over the past 55 million years. The presentday Przewalski's horse is believed to be the only remaining example of a wild horsei. , the last remaining modern horse to have evolved by natural selection. Another example of convergent evolution is the overall body structure of the shark and the dolphin. A shark is a fish and a dolphin is a mammal. However, their body shape and how they move through the ocean is very similar. Chapter 13: Evolution of Continents and Oceans The theory of plate tectonics is nowadays more or less universally accepted by geologists, and I have mentioned the basic idea briefly at. The theory of evolution by natural selection, first formulated in Darwin's book On the Origin of Species in 1859, is the process by which organisms change over time as a result of changes in. a type of evolution in which organisms are thought to have the same ancestor, but separated over time. convergent evolution a type of evolution in which organisms are of. This article describes an example of convergent evolution in humans. Research a different example of convergent evolution in another organism. Explain, in general terms, how that trait evolved in the different organisms. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Example of Vestigal structures. Snakes having vestiges of the pelvis and leg bones. Explain convergent evolution and describe how analogous structures can rise. PETERSONECHS Define, discuss, and given an example of how each of the following isolating mechanisms contributes to speciation in organisms. Ecological (including seasonal) isolation C. Polyploidy STANDARDS: The concept of speciation was worthy of points, but a student could achieve a score of 15 without. What is convergent evolution and what are some examples of convergent evolution between marsupial and placental mammals? Convergent evolution is the appearance of similar traits in distantly. The term coevolution is used to describe cases where two (or more) species reciprocally affect each other's evolution. So for example, an evolutionary change in the morphology of a plant, might affect the morphology of an herbivore that eats the plant. Convergent evolution is natural selection that favors the same type of structure in different ancestors. The similarity between convergent evolutionaffected species is called homoplasy, which. Then, we looked at the real example of Darwin's finches, which underwent adaptive radiation, or divergent evolution that occurs rapidly and causes a species to 'radiate' into many new species. The Difference Between Analogy and Homology in Evolution. Evolution Evidence Convergent evolution is when two unrelated species undergo several changes and adaptations to become more similar. Another example is the fins on a shark and a dolphin. Sharks are classified within the fish family while. What's interesting about the evolution of cetaceans is that their adoption of more fishy characteristics represents not just an example of divergent evolution, but convergent evolution as well. Convergent evolution takes place when species of different ancestry begin to share analogous traits because of a shared environment or other selection pressure. For example, whales and fish have some similar characteristics since both had to evolve methods of moving through the same medium: water. This quiz covers the basics of evolution by natural selection, including concepts such as comparative anatomy, DNA evidence, and observations made by Darwin on the Galapagos Islands. Evolution is the process of an organism changing to better ensure survival. Coevolution is the process of two organisms evolving at similar times and speeds, and where their r elationship is. What are 2 examples of convergent evolution? One of the most famous examples of convergent evolution is the camera eye of cephalopods (e. [5 What is divergent evolution and convergent evolution and give an example of each one. For example, convergent evolution can cause unrelated sequences to be highly similar. Although the occurrence of convergent evolution is generally accepted at the level of morphology, it is frequently ignored at the molecular level even though its occurrence at this level is well established. Examples of convergent evolution are wings of insects, birds, bats, streamlined body of dolphins and shark, whereas that of Darwin finches (kind of birds) is the example of divergent evolution. In convergent evolution, species evolve from the different species but develops similar characteristics, like wings of birds and insects. quizlet evolution unit test study guide directions o answer the following questions on a separate loose guide key 1 explain how domestic dogs are an example of articial selection dogs are selected for answer key unrelated species can evolve similar traits through convergent evolution study guide b Homology and homoplasy: : features and relationships 10 Feb 2005. To test phylogenetic hypotheses, scientists must be able to find out which similarities indicate a close relationship between species and which do not. As a rule, convergent evolution occurs when two groups of largely unrelated organisms are exposed to very similar environments and develop similar adaptations to survive. According to Princeton University, the evolution of the wing among bats and birds is convergent, as their last common ancestor. Several interactives and videos teach students about adaptive traits, convergent evolution, and the formation of new species. All the materials are based on real. An example of convergent evolution is the similar overall body structure of sharks and dolphins. The shark is a fish while the dolphin is a mammal, but their bodies have evolved to become similar. Another example is the adaptations for gliding found in both sugar gliders and flying squirrels. An example of convergent evolution is the similar nature of the flightwings of insects, birds, pterosaurs, and bats. All four serve the same function and are similar in structure, but each. Convergent evolution demonstrates evolutionary relationships. Homologous structures are the same body parts that are modified in different ways in different lines of descent from a common ancestor. When people hear the word evolution they most commonly think of divergent evolution, the evolutionary pattern in which (for example) two species gradually become increasingly different. Divergent evolution occurs when a group from a specific population develops into a. Homology, in biology, similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor. Homology is contrasted with analogy, which is a functional similarity of structure based not upon common evolutionary origins but upon mere similarity of use.
