An example of natural selection in a tropical butterfly species has been seen in the species bolina. The male population of bolina has developed a way to fight against a highly invasive, male-killing bacteria. The bacteria kills the males before they hatched from the egg, and was so successful, the male population of the butterfly dropped to 1% at its' lowest point. In than five years, after the adaptation of the male, the male population of butterflies has increased to 39%. Researchers believe this may be the fastest response and recovery to an environmental pressure that has been observed. How could the male butterflies manage such a fast response to the male-killing bacteria?

Female butterflies in the population that survived had a genetic adaptation that allowed them to transform into male butterflies.

Female butterflies in the population that survived were able to protect the male eggs from the bacteria and provide extra care for the male offspring.

Female butterflies can reproduce quickly so the males that survive are able to pass their favorable trait to their offspring.

Male butterflies in the population that survived were able to prey on the bacteria that was in the egg cells of the butterflies.
