Which of these is NOT an assumption made by HWE? Group of answer choices Mating is random No adaptation Infinitely large population No natural selection No mutation
Charles Darwin, brn in England,postulated natural selection, he assorted that only the strongest and fittest will survive and this he called natural selection . His theory was that the weaker species will eventually die and the strongest species will survive. Relate this theory to one from the 19th or 20th century.
Which of the following is not true of natural selection?(a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traitsacquired during an individual’s lifetime (d) natural selection Test Your Understanding acts on a population’s genetic variability, which arisesthrough mutation (e) natural selection may result in changes in allele frequencies in a population
Alfred Russel Wallace and Charles Darwin argued that evolution by means of natural selection involves all of the following steps except: a. variation is present in all species b. species can produce more offspring than the environment can sustain c. all individuals within a species have equal chances to improve their fitness d. those individuals that are more fit will survive and reproduce in the greatest numbers e. over time, the species will evolve as the more fit individuals replace the less fit individuals
Which statement is true? Explain your answer. A. Natural selection acts on populations, not on individuals. B. Mutations care the raw material for natural selection. C. Evolutionary change occurs at the level of the individual. D. Developmental change is a population-level process. E. Species are simply those organisms that share similar phenotypes.
Which of the following statements is NOT an observation or inference on which natural selection is based? Group of answer choices Only a fraction of an individual’s offspring may survive. Species produce more offspring than the environment can support. There is heritable variation among individuals. Modifications of an organism acquires during its lifetime can be passed to its offspring.
You find an isolated, natural pond (call it pond #1) with a population of 400 Danio kerri. Evolution in this isolated population of 400 blue danio could be due to _______. Group of answer choices natural selection (only) genetic drift (only) mutation (only) Natural selection and genetic drift, but not mutation. natural selection, genetic drift and/or mutation
Which evolutionary process is most responsible for the increased occurrence of tusklessness in female elephants in Gorongosa National Park? a)Sexual selection b)Mutation c)Natural selection d)Genetic drift Im thinking either b or c but im not sure mabye c but im not really sure about the whole thing
How can Darwin's finches explain natural selection and descent with modification? What is another example of natural selection and descent with modification? In both of your answers, you should describe the trait that was selected for/against and why this trait was an advantage/disadvantage. Plus, state how natural selection changed the population over time.
For natural selection to occur, there must be competition for resources, competition for survival, or 15) different reproductive success. Why is this so? A) Without competition, there is no pressure to mutate.B) The struggle of competition makes individuals stronger.C) Natural selection acts on the different abilities of individuals to survive and pass on their genes to the next generation.D) Populations evolve to preserve the species and don't change unless they must. Then explain why the answer is correct and why the others one are inccorect.
Which aspect(s) of natural selection is(are) illustrated by the figure below? Check ALL answers that apply. A. Variation among individuals must be genetically transmissible to the next generation. B. Variation must exist in a population. C. Variation among individuals leads to differences in lifetime reproductive success. D. More individuals are produced each generation than the environment can support, resulting in competition for survival.
