evolution test questions | latest 2023/2024 Evolution is the process of (1) development of once-celled organisms from mammals (2) change in species over long periods of time (3) embryonic development of modern humans (4) changing energy flow in food webs - 2 Which phrase best defines evolution? (1) an adaptation of an organism to its environment (2) a sudden replacement of one community by another (3) the isolation of organisms from each other for many years (4) a process of change in species over a period of time - 4 The study of fossils has allowed scientists to (1) describe past environments and the history of life (2) study present ocean temperatures at different depths (3) analyze the chemical composition of sedimentary rocks and minerals (4) describe the details of the process by which life first began on Earth - 1 The evolution of species is often represented as a branching tree similar to the one shown in the diagram below. The names shown below represent different groups of organisms alive today; the lines represent their evolutionary histories. The statement that is best supported by the diagram is that 1. Annelida and Arthropoda have an ancestor in common 2. Echinodermata are more closely related to Mollusca than they are to Chordata 3. Mollusca and Arthropoda evolved before Porifera 4. Annelida and Arthropoda evolved from Echinodermata - 1 What inference can best be made based on the diagram? 1. adaptations for living in trees are inherited by all primates 2. humans and apes have a common ancestor 3. the embryos of monkeys and apes are identical 4. the period of development is similar in most pronates - 2 The process of natural selection is based on the assumption that (1) environmental changes will cause changes in body structure in individuals (2) most changes from generation to generation are the result of mutations (3) part of the population of organisms always remains stable (4) different traits inherited by offspring have different survival value - 4 the loss of flying ability by the beetle is most probably the result of 1. predators eating the beetles wings 2. beetles not using their wings 3. genetic changes in the beetles 4. lack of vegetation for the beetles to feed on - 3 the graph indicates that the non-flying beetles probably 1. were better adapted to the environment 2. arrived from other islands 5000 years ago 3. mutated and produced flying beetles 4. became extinct about 1.5 thousand years ago - 1 When lions prey on a herd of antelope, some of the antelope are eliminated. Which part of the theory of evolution can be used to describe this situation? (1) asexual reproduction of the fittest (2) isolation of the species (3) survival of the best adapted (4) new species development due to mutation - 3 Every spring, each mature female fish of a particular species produces several million eggs. However, the total population of this species remains at around 10,000 from one year to the next. State two reasons why the fish population remains approximately the same from one generation to the next. - Predators can eat the fish. and not all eggs are fertile. Over many years, the climate on the west side of the island has undergone drastic changes while the climate on the east side has remained the same. it is most likely that population b will 1. migrate and intermix with population a 2. become extinct 3. have evolved more than population a 4. have evolved less than population a - 4 The organisms of population a and population b are now incapable of interbreeding and producing offspring. which biological process most likely caused this situation to occur? 1. artificial selection 2. cloning 3. natural selection 4. asexual reproduction - 3 which graph shows the most probable results that would occur in the distribution of wing color in this moth population after a long period of time? 1. b has the most. g and w have a little 2. b and g have the most. w has the least. 3. w has the most. b and g have the least. 4. g has the most. then the white. the b has the least. - 4 As a result of the fungus infection, the change in moth wing color distribution would most probably occur by the 1. production of sex cells by mitosis 2. natural selection of favorable variations 3. eating of pigments in fungus spores 4. production of mutations as a result of eating the fungus - 2 Which statement is basic to the theory of evolution by natural selection? (1) In general, living organisms maintain a constant population from generation to generation (2) Changes in living organism are almost completely the result of mutations (3) Natural variations are inherited (4) There is little competition between species - 1 Which statement is not included as a part of or modern understanding of evolution? (1) Sexual reproduction and mutations provide variations among offspring (2) Traits are transmitted by genes and chromosomes (3) More offspring are produced than can possibly survive (4) New organs are formed when organisms need them - 4 The modern theory of evolution states that a basis for variation within a species is provided by (1) mutations (2) asexual reproduction (3) cloning (4) overproduction - 1 Sexual reproduction is relation to evolution because sexual reproduction (1) occurs only in more recently evolved forms of ani
