Final answer:
The data suggests that selection pressure may be operating on the population of bats in the cave. The number of bald bats has increased over time, indicating a possible shift in allele frequencies.
Step-by-step explanation:
The data provided in the table suggests that selection pressure may be operating on the population of bats in the cave. In 2005, the majority of the bats were hairy (carrying the dominant H allele), and only a small number were bald (carrying the recessive h allele).
However, in 2015, the number of hairy bats decreased significantly, while the number of bald bats increased. This change in allele frequencies indicates that natural selection is favoring the bald phenotype, possibly due to environmental factors or other selective pressures.
