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

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
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.
Darwin and Lamarck had very different ideas on how life on earth got to be the way it is now. However they had some similar beliefs as well. What four ideas did they agree on? Explain Lamarck’s Theory of Inheritance of Acquired Characteristics. Explain Darwin’s Theory of Natural Selection. Describe how Darwin’s theory was supported and Lamark’s theory was disproved.
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.
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
Vhy was natural selection controversial to biologists in Darwin's time? It was a cruel and unfair principle as to why species change. B) It went against the religious beliefs of the time. There was no evidence that descent with modification during Darwin's time. He had no explanation for how advantageous traits were passed from parent to offspring.
Which of the following best describes natural selection? O It is a guess made by scientists about how life develops, but it has no hard evidence to support it. It is the idea that the strong survive and the weak die off. It is the idea that organisms with genetic traits that improve their ability to reproduce are more likely to pass those traits on to future generations. It is the idea that organisms naturally increase in complexity and intelligence with time.
While hiking in the andes mountain in south america, darwin found a glyptodon fossil that resembled the modern armadillo. This evidence was used by Darwin to support his theory of natural selection by showing how species have..
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 False
Darwin believed that natural selection worked in a way that was similar to the selective breeding of farm animals. O True O False
Four of the five factors below support the mechanism of natural selection. In contrast, the fifth factor blocks natural selection from occurring. Which one of the factors listed below does NOT lead to natural selection, but instead stops it from occurring? O Characteristics are inherited - passed from parent to offspring. O Organisms in a population are identical to each other. O There is competition among organisms in a population. O More offspring are born than can survive. O Organisms in a population vary in characteristics that affect how well they survive and reproduce. o o oO
What is the difference between artificial selection and natural selection? How did Darwin's studies and experiments with artificial selection help him articulate how natural selection works?
