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 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.
Although Charles Darwin is best known for developing his theories of evolution during his trip on the HMS Beagle, his later life also provided evidence for evolution. Explain how Darwin’s later life added to his evolution theory.

- Of the 500 eggs produced by a particular frog, only 10% developed into adult frogs. Which part of Darwin’s theory does this best illustrate? favorable mutations are not inherited. mutations occur by chance. there is a struggle for survival among organisms. populations are not stable.arrow_forwardWhen Darwin wrote On the Origin of Species, he spent a significant amount of time on a topic he considered to be (in his words) “one special difficulty” to his theory: eusociality. Explain why eusociality constitutes a “difficulty” to the theory of evolution by natural selection, and how evolutionary biologists have been able to explain its evolutionarrow_forwardAlfred Russel Wallace and Charles Darwin accepted all of the following claims about evolution by means of natural selection, with the exception of: over time, the species will evolve as the more fit individuals replace the less fit individuals species can produce more offspring than the environment can sustain those individuals that are more fit will survive and reproduce in the greatest numbers variation is present among individuals of all species E. all individuals within a species have equal chances to improve their fitnessarrow_forward
