Step 1
Relates the general principles of Darwin/Wallace’s theory of evolution to survival and recovery of rabbits
Answer
Darwin/Wallace’s theory of evolution emphasizes the importance of variation within a population and the concept of natural selection. Initially, the virus significantly reduced the rabbit population, leaving only a few that had genetic traits allowing them to survive. Over time, these surviving rabbits reproduced, passing their resistant traits to their offspring. As a result, the population began to recover, increasing the proportion of rabbits that were resistant to the virus.
