Quiz · Common Misconceptions About Natural Selection

Question 1What is the main aim of the lecture?

To prove that evolution follows a fixed plan To introduce new evidence about genetic drift To describe the life cycle of the peppered moth To correct common misconceptions about natural selection

Question 2According to the lecture, what actually happened to the peppered moth?

The moths deliberately turned dark to hide Darker variants survived better on polluted trees Pollution directly changed the colour of wings Lighter moths adapted faster than dark ones

Question 3What does the phrase survival of the fittest really refer to?

The physical strength of each individual The speed at which organisms can evolve Reproductive success in a given environment The ability to survive natural disasters

Question 4According to the speaker, what actually changes across generations?

Populations, as certain traits become more common Individuals, as they adapt during their lifetimes Textbooks, as new examples are discovered Environments, as pollution slowly disappears

Question 5What can genetic drift do when populations become dangerously small?

Eliminate beneficial traits by random chance Create new traits through deliberate selection Guarantee the survival of the strongest members Speed up adaptation to a new environment

Question 6What happened to the early interpretations of the peppered moth study?

They were questioned, then broadly confirmed They were accepted without any criticism They were replaced by entirely new data They were quietly removed from textbooks

Question 7Which individuals tend to prevail in natural selection, according to the speaker?

Those with the greatest physical strength Those best suited to their particular circumstances Those that live the longest and healthiest lives Those that are able to change colour quickly

Question 8Which idea is closest in meaning to saying evolution does not strive towards perfection?

Evolution produces flawless organisms over time Evolution stops once a species is well adapted Evolution has no goal of creating perfect beings Evolution works only under perfect conditions

Question 9What does the lecture say about evolution at the level of the individual?

Individuals evolve whenever environments shift Individuals evolve faster in small populations Individuals pass evolved traits to their parents Individuals do not evolve during their lifetimes

Question 10How does the speaker describe evolution in the conclusion?

A steady march towards higher complexity A plan that favours the strongest species A process that has recently come to an end An ongoing response to shifting environments
