- Compare Darwin’s description of natural selection asquoted on page 765 with Wallace’s description of the tendency of varieties to depart from the original type quotedbelow it, on the same page. What ideas do they have incommon?Evolution _______ natural selection. a. is the same as c. is the goal of b. can oc d. explains the origin of life byOffically speaking, did Charles Darwin develop the theory of "evolution" or the theory of "descent with modification?" I know he coined the second term but I can't find if that's all he's historically creditited with.
- State which mechanism of evolution is occurring. For the scenario(s) involving natural selection, state which type of natural selection is involved.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 FalseWhich 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
- Darwin’s idea on evolution by natural selection has been disproven when it comes to the origin of life because Pasteur discredited spontaneous generation.A) True.B) True, with regards to origin of life only; natural selection applies to later lifeC) False. Pasteur’s experiment discredited ideas that complex organisms (e.g., mice) could arise in weeks or months later from inanimate matter (e.g., cloth) or from other organisms (e.g., grain). Pasteur’s experiment does not discredit the possibility of simple life evolving over billions of year. Some scientists vigorously rejected Darwin’sideas when On the Origin of Species was published. Richard Owen (1860), perhaps the mostrespected biologist in England, wrote (amongmany other objections): “Are all the recognisedorganic forms of the present date, so differentiated, so complex, so superior to conceivableprimordial simplicity of form and structure,as to testify to the effects of Natural Selectioncontinuously operating through untold time?Unquestionably not. The most numerous livingbeings … are precisely those which offer suchsimplicity of form and structure, as best agrees…with that ideal prototype from which…vegetableand animal life might have diverged.” Howmight Darwin, or you, argue against Owen’slogic?The theory of evolution is most accurately described as Group of answer choices A. Nn opinion that some scientists hold about how life originated on Earth. B. An overarching explanation, supported by much evidence, for how populations change over time and new species arise from ancestral species. C. One possible explanation, among several scientific alternatives, about how species have come into existence. D. An educated guess about how species originate. E. An idea about how acquired characteristics are passed on to subsequent generations.
- Which must exist in a population before natural selection can act upon that population? A. Genetic variation among individuals B. Variation among individuals caused by environmental factors C. Sexual reproduction D. Three of the responses are correctDefi ne what is meant by the term evolution.State 5 facts and 3 inferences Darwin used to construct the theory of Natural Selection. I'm confused I've listed overproduction, variation, and adaptation as the three inferences, but I do not know what to put for facts because what I've listed might belong under the facts category. Thanks!
