- According to Darwin, which of the following would limit an individuals' reproductive success? Question 16 options: They display strong mate selection. They produce few and infrequent offspring. They are more likely to survive environmental changes than others in their species. They have many inheritable traits.Darwin believed that natural selection worked in a way that was similar to the selective breeding of farm animals. O True O Falsea statement of how sexual selection differs from natural selection has to be a statement that is wrrtien in a essay
- Which of the following is NOT one of Darwin's postulates? Individuals in a population will have different versions of phenotypic traits Individuals in a population will vary in how successful they are with respect to survival and reproduction Some phenotypic traits can be passed from parent to offspring Individuals change in response to the environment, and pass those changes on to the next generationAnother way to say "Natural Selection" is: differential success in reproduction mutation selective breeding differential access to mating partners variation O preferential sex choicesWhich statement does NOT represent one of Darwin's observations? Some characteristics are heritable and passed on to offspring. Changes in populations are gradual and take place over long periods of timme. Members of the same species may exhibit considerable variation. Some characteristics afford their possessor a better chance of survival All individuals have an equal chance to survive and reproduce.
- Why is the following observation by Darwin important to the theory of evolution? "All species can produce more offspring than their environment can support, and many of these offspring fail to survive and reproduce" Organisms have evolved to produce as many offspring as possible Many organisms die for reasons having nothing to do with their evolutionary fitness Competition for resources creates the selection that drives evolution O Over time, organisms that have larger litters will be more evolutionarily successfulNatural selection can lead to adaptations over time. O True O FalseWhich of these is needed for natural selection to occur? O genetic variation asexual reproduction environmental stability genetic engineering
- Darwin's theory of natural selection forms the basis of our understanding of evolution, but it was incomplete. He did not know the mechanism that produces variation. Group of answer choices True FalseWith which statement would Darwin most likely have agreed? * Competition among individual species causes heritable variations Variations are caused by Natural selection Organisms best adapted to a particular environment are the most likely to reproduce. No answer Survival of any species is proportional to the inheritance acquired characteristics.What was the most important idea of Lamarck's theory of evolution that contributed to Darwin's theory? Organisms could be grouped according to similarity. Selection could operate on individuals, instead of on species as a whole. O Within a species, there was lot of variation between individuals. Individuals could change in response to the environment, and this acquired trait was passed on. Indoor Playgrow W
