Which of the following is a true statement about Charles Darwin?Group of answer choicesHe based his theory on the inheritance of acquired characteristics.He was the first to discover that living things can change, or evolve.He proposed natural selection as the mechanism of evolution.He worked out the principles of population genetics.

In his book On the Origin of the Species, Charles Darwin described how species change over time. Which of the following is NOT part of his observations that describes the mechanisms of natural selection? Group of answer choicesDisease and natural disaster will limit population growth.Species today descended with modifications from ancestral species.Organisms produce more offspring than can survive.Organisms with advantages will survive and reproduce.

Darwin and Wallace's theory of evolution by natural selection was revolutionary because it ________.Question 3Select one:a.was the first theory to refute the ideas of special creationb.proved that individuals acclimated to their environment over timec.dismissed the idea that species are constant and emphasised the importance of variation and change in populationsd.was the first time a biologist had proposed that species changed through time

What were the three key observations made by Darwin that allowed him to deduce that natural selection is a primary driver of evolution?Group of answer choicesSpecies change due to the next generation inheriting genes based on their parent's behaviors.Gene flow and mutations provide the right changes for future generations to thrive.Organisms produce more offspring than survive, variation exists among individuals, and advantageous variations increase in relative frequency over time.The number of adults tends to remain the same over time, individuals vary little over time, and natural selection works on only the best of those adults in each generation.

Because he was well aware of the effect his theory of evolution would have on the public and on the Church of England, Darwin delayed publishing his work for several decades while he gathered additional evidence. After invoking selective breeding of domesticated species as evidence that groups of organisms are capable of change, he then proposed that natural populations can change as well. On which two lines of evidence did he base this proposal?Group of answer choicesOrganisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.Organisms produce more offspring than can be supported by their environment, and adaptations to specific environments increase an organism's ability to survive and reproduce.Some individuals leave more descendants than other individuals, but the individuals in a population are essentially identical to each other.Some individuals within a population have greater survivability and reproductive success than others, and favorable traits within a population will accumulate over generations.
