Darwin put together several pieces of information when formulating his theory of evolution. Which of the following is/are not part of that information? Choose All That Apply Natural populations of organisms display variable phenotypes Natural populations tend to produce more offspring then the environment can support Individuals within a population can pass on traits acquired during their lives to their offspring Organisms tend to be uniquely adapted to the environments in which they are found Each individual in a population is equally likely to survive and produce offspring

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 generation
The process of natural selection can be described as Group of answer choices 1. an organism changing during its life to be better suited for its environment 2. a cell dividing 3. traits that cause individuals to live longer or reproduce more are seen more often in the next generation 4. none of the above
Which of the following are important ideas used by Darwin were based on views expressed by Lamarck? (Choose all that apply) Hint: review slide presentation which provides more detail than textbook O Changes that an organism acquires during its lifetime are passed to its offspring "acquired traits". D all species change through time Organisms change in response to their environment. New characteristics are passed from one generation to the next.
Which 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.
Naturalists who have accepted evolutionary theory now propose that: all of the items listed extinction occurs when the food supply becomes nutritionally unbalanced O populations of plants and animals in nature most often consist of individuals that are clones of each other populations of a species that become isolated from others by adapting to different environmental niches quickly become extinct those individuals whose variation gives them an advantage in staying alive long enough to reproduce are more likely to pass their traits on to the next generation
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
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 traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
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 successful
Natural Selection Fill in the blanks to explain Darwin's theory of Natural Selection using these words: DNA, survive, variation, DNA, reproduce 1. Individuals in a species show 2. This is because of differences in their 3. Individuals with characteristics which suit the environment are more likely to and 4. So the from these individuals is passed onto the next generation.
Which the following statements about Darwin's theory of natural selection is true? O In order to reproduce more successfully, an individual must evolve so that it adapts to its environment. The natural environment consistently causes variation of certain traits in the population. O Individuals with inherited traits that are better suited to the local environment are more likely to survive and reproduce than less well-suited individuals. Natural selection, by its cumulative effects over long periods of time, could have caused random changes in ancestral species, thus giving rise to two or more descendant species.
With 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.
Which is an example of an evolutionary adaptation? Group of answer choices constancy in the rate of accumulation of genetic changes in a molecule over time the loss of an allele in a population due to a population bottleneck fixation in a population of a selectively advantageous allele a change in frequency of a neutral allele by genetic drift
